related APIs now take a device pointer instead of an index.
All functions that take a CPU device are prefixed with cpu_*
All functions that are globally related to cpu execution
are prefixed with cpuexec_*. Below is a list of some of the
mappings:
cpu_boost_interleave -> cpuexec_boost_interleave
cpunum_suspend -> cpu_suspend
cpunum_resume -> cpu_resume
cpunum_is_suspended -> cpu_is_suspended
cpunum_get_clock -> cpu_get_clock
cpunum_set_clock -> cpu_set_clock
cpunum_get_clockscale -> cpu_get_clockscale
cpunum_set_clockscale -> cpu_set_clockscale
cpunum_get_localtime -> cpu_get_local_time
cpunum_gettotalcycles -> cpu_get_total_cycles
activecpu_eat_cycles -> cpu_eat_cycles
activecpu_adjust_icount -> cpu_adjust_icount
cpu_trigger -> cpuexec_trigger
cpu_triggertime -> cpuexec_triggertime
cpunum_set_input_line -> cpu_set_input_line
cpunum_set_irq_callback -> cpu_set_irq_callback
In addition, a number of functions retain the same name but
now require a specific CPU parameter to be passed in:
cpu_yield
cpu_spin
cpu_spinuntil_time
cpu_spinuntil_int
cpu_spinuntil_trigger
cpu_triggerint
Merged cpuint.c into cpuexec.c. One side-effect of this
change is that driver reset callbacks are called AFTER the
CPUs and devices are reset. This means that if you make
changes to the CPU state and expect the reset vectors to
recognize the changes in your reset routine, you will need
to manually reset the CPU after making the change (since it
has already been reset).
Added a number of inline helper functions to cpuintrf.h for
managing addresses
Removed cpu_gettotalcpu(). This information is rarely needed
outside of the core and can be obtained by looking at the
machine->cpu[] array.
Changed CPU interrupt acknowledge callbacks to pass a CPU
device instead of machine/cpunum pair.
Changed VBLANK and periodic timer callbacks to pass a CPU
device instead of machine/cpunum pair.
Renamed all information getters from cpu_* to cpu_get_* and
from cputype_* to cputype_get_*.
* sndindex now considered as well in state save
* expose discrete_sound_n_r(void *chip, ...) to enable accessing multiple discrete sound cores
Curt Coder, is this sufficient?
* implemented support for phi1/phi2 transparent addressing
* added callback to communicate address back to driver
Implementation is not and can not be "clock" accurate since the timing is totally up to the hardware implementation. It is the main cpu and hardware which determines phi clocking and when data is written to video ram. The only support in the 6545 is that the update address is latched out to the ma lines during phi2.

have no dependencies on the live CPU), and the validity check.

these are now the preferred means of manipulating a CPU
* removed the cpunum_* calls; added an array of cpu[] to the
running_machine object; converted all existing cpunum_* calls
to cpu_* calls, pulling the CPU device object from the new
array in the running_machine
* removed the activecpu_* calls; added an activecpu member to
the running_machine object; converted all existing activecpu_*
calls to cpu_* calls, pulling the active CPU device object
from the running_machine
* changed cpuintrf_push_context() to cpu_push_context(), taking
a CPU object pointer; changed cpuintrf_pop_context() to
cpu_pop_context(); eventually these will go away
* many other similar changes moving toward a model where all CPU
references are done by the CPU object and not by index
* cpu/i8x41 should be renamed to UPI-4x, since UPI-41/42 was an intel chip family
postponed for now until core moved to pointers.
* removed I8041 definition from mcs48
* removed I8x41 cpu definition and config struct
* added I8041, I8741, I8042, I8242 and I8742 cpus to i8x41.c
* added internal memory maps
* internal ram now uses DATA memory space
* updated drivers
* increased interleave to 70 in decocass. This fixes decocass hanging in countdown around 13

Subject: [patch] Add ADDRESS_MAP_NAME macro
Hi mamedev,
In theory, MAME's interface macros should completely hide the naming
conventions from the drivers and sound/cpu cores. So as an
experiment, I renamed all the core apis and looked to see what broke.
The most common api coupling was with address maps in the CPU cores,
which this patch addresses by introducing a new macro,
ADDRESS_MAP_NAME (mimicing what is done in devintrf.h). There were a
handful of related problems in some drivers which this patch also
fixes. Some remaining issues I left alone (laserdisk apis reference
rom, video_update, machine_config, ksys573 use of nvram_handler,
megadriv use of ipt), in principle all the apis need _NAME variants to
encode the conventions.

Defined macros for core CPU functions: CPU_INIT, CPU_RESET, CPU_EXIT,

Changed init, reset, exit, and execute interfaces to be passed a
const device_config * object. This is a fake object for the moment,
but encapsulates the machine pointer and token. Eventually this will
be a real device.
Changed the CPU IRQ callbacks to a proper type, and added a device
parameter to them.

Subject: Z80 CPU change
Hello Aaron,
For a long time there was undiscovered internal register (MEMPTR) inside Z80 CPU which was visible by using BIT n,(HL) instruction in undocumented bits of flag, in
last few months lot of things have been discovered by team of Russian programmers. There was a test on real machine which showed status of flags after each instruction.
I am sending you now patch for Z80 with MEMPTR implemented, there is also one more bug fixed (BIT 6,(XY+o) was not implemented good it used BIT 4,(XY+o) code).
As a proof that things are now valid, I am sending screens before patch on Z80 cpu core, and after with compare of results on real machine.
I am also sending you a TZX file (for ZX Spectrum) since tests are done inside that driver.
Please inform me about status. Hope this could fix some issues in drivers using Z80, since some games used this flags.

Subject: fix for Cube Quest Line CPU emulation
I found a bug in the emulation of the Cube Quest Line CPU.
Proof of bug:
After looking at .diff,
Assume 'ci' is 1, and assume 'r' and 's' are both 0xFFF
(0xFFF equals -1, as these numbers are 12-bit signed).
The result should be mathematically equivalent to -1 - (-1)
which is 0.
~0xFFF is 0xF000, so you'd have 0xF000 + 0x0FFF + 1 which equals
0x10000 but since 'res' is 16-bits this is truncated to 0x0.
'C' then becomes 0 and 'V' becomes 1 (as I recall). The result of
0 is correct, but the flags are wrong; V should be 0 and C should
be 1.
Under my proposed fix, you'd have 0x000 + 0x0FFF + 1, which equals
0x1000, so the lower 12 bits are 0 (correct) and C is 1 and V is 0
(correct).
I discovered this bug while disassembling the line CPU's ROM.
means that multiple changes without any execution will be seen as
atomic. It also means that PULSE_LINE no longer works for signalling
IRQs.
Added checks in the debug build to catch people who try to use
PULSE_LINE for non-NMI and non-RESET input lines on CPUs that no
longer support direct interrupt generation. Over time expect this
list to increase.
machine/device handlers. Unfortunately, the implementation relies on
sentinel values to distinguish a port tag versus a pointer to function
code. However, since this is a very common situation, it will hopefully
be worth the slight grossness. New macros are defined in inptport.h:
DEVICE8_PORT(name) - use this to specify the name of a port to read
wherever a read8_device_func would normally be used
MACHINE8_PORT(name) - same as DEVICE8_PORT except it can be used
wherever a read8_machine_func would normally be used
IS_HANDLER_PORT(ptr) - accepts a read8_device_func or read8_machine_func
and determines if it is an actual function or a reference to a port;
intended for use by devices that accept DEVICE8_PORT-style functions
CALL_DEVICE8_READ(ptr,device,offset) - either calls through the given
read8_device_func, or calls input_port_read with the appropriate
tag, depending on the result of IS_HANDLER_PORT; intended for use
by devices that accept DEVICE8_PORT-style functions
CALL_MACHINE8_READ(ptr,machine,offset) - same as CALL_DEVICE8_READ
except for read8_machine_func
Note that in order for these to be useful, the consumer of the function
pointer must be enhanced to use the CALL_* macros above instead of directly
calling through the function. So far, only the 8255 PPI is set up to do
this, as part of the cleanup below. Also note that the sentinel value is
currently 4 consecutive 0 bytes; this may need to change in the future, in
either length or value, so it is important to stick to the macros above.
8255 PPI interface cleanup:
- added MDRV_PPI8255_ADD, MDRV_PPI8255_RECONFIG and
MDRV_PPI8255_REMOVE macros; updated all drivers to use them
- changed callbacks to device read/write handlers intead of
machine read/write handlers; updated all drivers accordingly

Changed Z80 daisy chain interface to simply be a list of
devices in the chain. Interrupt callback functions are now
fetched via the standard device interface and referenced by
the daisy chain code.
Changed Z80 PIO interrupt callback to pass a device instead
of the machine. All device callbacks should provide the
device.

specified, these palettes specify a 32-entry (RGB15) or 256-entry
(others) lookup for applying additional brightness/contrast/gamma
on a per-texture basis.

violated proper layering.
Renamed palette_set_brightness() to palette_set_pen_contrast() for

Modified the laserdisc core to leverage the pre-decoded frame
metadata, which is now required. This improves seek times when
searching and allows the player-specific emulation access to the
VBI data as soon as it would really be available. Changed update
callback timing to fire just before the first line of VBI data

Converted PR-8210 emulation over to using the actual MCU from the

Converted Simutrek-hacked laserdisc emulation to using the actual

for this new support to work.
Clickable input support. Mostly by Nathan. A few changes from the
proposal:
* as far as the layout is concerned, states are 0 (off) or 1 (on) and
aren't impacted by the port's ACTIVE_HIGH or ACTIVE_LOW
* instead of checking each individual field for a hit, we look to see
what is hit once per frame and then just check against that; this
is faster, but does limit us to a single hit item
* added function input_field_by_tag_and_mask() to look up a particular
input_field_config by tag and mask; this makes it possible to easily
get the port default value or other information as necessary
is either DEVICE_START_OK or DEVICE_START_MISSING_DEPENDENCY. The latter
should be returned by a device if there is another device it depends on
which hasn't been started yet. Added new flag in the device interface to
indicate whether a device has been started.
Changed laserdisc interface to explicitly specify the screen and sound
devices it should route to. Drivers no longer have to manually call
laserdisc_vsync(). Instead, the laserdisc code connects up to the routed
screen device and works based on that screen's VBLANK timing. Removed
all existing calls to laserdisc_vsync().
Changed laserdisc behavior so that it completes the previous video read
and initiates the next read at the end of VBLANK instead of the beginning.
This gives player logic time during VBLANK to alter the slider position
prior to fetching the next frame.
Added new laserdisc callback for vsync begin and changed the update
callback to be called at the end of VBLANK. Also added functions to set
the slider speed, advance the slider, and directly control the video/
audio squelch. In addition, there is a new status function to get the
slider position in general terms.
Added parameter to the VBLANK callbacks supported in emu/video.c. Updated
all callers to provide a callback value.
Fixed bug that would cause watchpoints to trigger if you had a memory
window open to the watchpoint address.
Further updates to the PR-8210 ROM simulation. Still not quite there but
the system is much better understood now. Added layout to the PR-8210
which displays the state of the front-panel LEDs.
now have their tags auto-prefixed with the device's tag. This allows for
multiple instances to be present. For example, the PR-8210 laserdisc player
has a CPU with a tag of "pr8210". When it is included as a device by a
driver, the driver may tag the device "laserdisc". The resulting final
CPU tag name will be "laserdisc:pr8210". Also updated the debugger
expression engine to support names with embedded colons.
Added warnings to ensure that tags used for CPUs, sound chips, regions, and
devices follow some basic rules: they should be less than 12 characters long,
be all lower-case, and only contain letters, numbers, underscores, or dots
(no spaces). This is to ensure that they can be used properly in debugger
expressions and don't get too long or unwieldy to type (even 12 chars is a
bit long).
also the default state, obviating the need for a default value. Removed
the "default" attribute as a result. Switching from "Off" to another
state first executes the "on" script followed by the "change" script.
Switching to "Off" from another state executes the "off" script. While
not off, the "run" script is executed each frame.
device to provide a set of ROM regions to be loaded along with the game
ROMs. It is expected that most regions defined for devices will use the
ROMREGION_LOADBYNAME flag to enable the ROMs to live in a central location.
Added new device interface selector: DEVINFO_PTR_MACHINE_CONFIG. This allows
a device to specify a partial machine driver which is appended to the end of
the machine driver for any game using that device. The intention for this is
to allow devices which have their own BIOS logic to specify CPUs and other
characteristics common to all systems using the device.
Added new ROMREGION flag: ROMREGION_LOADBYNAME, which means that if the ROMs
in that region are not found in the usual driver files, then the name of the
region will be used as a driver filename for loading.
Extended the ldcore interface structure to allow each player type to provide
its own ROM region and partial machine driver.
Moved preliminary PR-8210 emulation code from ldplayer.c to ldpr8210.c. It
is currently disabled behind the EMULATE_PR8210_ROM compile time flag.

CPC clone) BIOS, which periodically (about 7 or 8 times a second) checks
the flag to see if the date and time display on the BIOS setup screen
needs to be updated. Without the flag implemented, the date and time
are static on the setup screen, or if the time hasn't been initialised
(blank NVRAM) it is blank.
The BIOS function that does this basically checks bit 4 of register
0x0c, and if 0, ends there, otherwise it will read register 0x0b, sets
bit 7 of the result and writes it back to register 0x0b (presumably,
this resets the interrupt flags). Then it continues on to the display
refresh function.

Subject: a few patches
Hi,
enclosed please find a few patches that finally conclude my
input_port cleanups. I will still probably change some bit
here and there, but there will be no more massive changes
which could collide with current developments.
Notice that, after applying these patches, indexed input reads
remain only present in CPU interfaces (e.g. all the yamaha
interfaces when the sound cpu is used to read inputs) and no
more 16bit/32bit indexed read are present at all in MAME or
MESS source. Therefore, you may consider the removal of
input_port_N_word_r & input_port_N_dword_r, if you think you
don't need them anymore.
More in detail:
* patch01.diff & patch02.diff: conclude the cleanup for
drivers W -> Z
* primrage.diff: changes the start buttons with input buttons
in primrage, as per the test mode (no start button is reported)
and the control panel (see
http://www.mameworld.info/ubbthreads/showthreaded.php?Cat=&Number=161107 )
* drivedge.diff: makes drivedge ports fully 32bit and removes
the protection bit (which seems not to be used in this game, or
at least not in the port where it was tested since at least MAME
0.100)
* duplicate.diff: introduces a PORT_CUSTOM which returns a tagged
input (like a input_port_read). this could be useful for those
games which require to read the same 8bit (resp. 16bit) input in
both the upper and lower half of a 16bit (resp. 32bit) port. you
can see its use for this purpose in the modified drivers (fuukifg3,
dreamwld, cojag etc.)

fixed palette decoding of early SNK games (from marvins to athena + fitegolf). The least significan bits were assigned incorrectly.
merged marvins.c into snk.c, with all resulting fixes (removed hacks, correct shadows, scroll offsets etc)
This contains three different patches:
20080829.patch
Introducing the running_machine* parameter in a few more places. Next
step would be to make the execute_* function aware of it, if that's
OK. Also used the machine parameter in memory.c were it's available.
20080829_1.patch
The already discussed and probably being rejected removal of
dreprecat.h from debugger.h. I think this is a low-risk patch (we had
worse cleanups) and it lowers the risk of new code using deprecated
function beign introduced in MAME/MESS, because there is no invisible
inclusion of deprecat.h anymore (I think one driver - kofball.c - got
it with deprecated code).
20080829_2.patch
The last Machine -> machine conversion I had sitting in my local
tree. I know the proper way is to turn them into devices, but I still
haven't looked into that.
Each player now gets its own source file, along with new hooks
which enable more precise control over the behavior. Updated the
PR-8210 and LD-V1000 implementations to the new spec. Other
players will come online shortly.
Changed scan behavior so that it requires a constant stream of
signals to continue scanning. Updated ldplayer accordingly.
* Adds MCS48_INTERNAL_ROMBANK define to header
* Drivers which need to control the ea line have to initialize banking for internal/external rom
This is not yet optimal but works as expected with existing drivers and modified mario.c
* MB8884 is a I8035 ==> 12 addr, no internal rom map
* EA line high: external access - this is "default"
The whole EA implementation is as Aaron named it, cheeky. EA=1 external rom access, EA=0 internal rom access.
But all variants are treated the same, i.e. for i8035, MB8884, I8039, the external rom is used in the same
way as the internal.
These ports are actually ports which sink current on logical 0. With a logical 1, they are in high impedance mode and may be read. The high impedance is treated as logical 1 by TTL gates connected to them.
Fixed bug in my recent DISCRETE_MIXER update.
Note: the DISCRETE_MIXER bug caused most of the speed increase of its optimization and caused some games to crash. Donkey Kong is now at 14% faster on my machine then when I started. Better then nothing.
For those keeping score dkong was at 268% on my computer before I started optimizing. It now runs at 342%. The 555 and mixer changes also speed up just about every current discrete game.

Subject: [patch] Remove useless backslashes
Hi mamedev,
I've been using pmd 4.2.2 to analyze the MAME codebase for duplicate
code, and it's C parser complains about useless backslashes and
dangling defines in #if...#endif sections. Here's a patch that fixes
this, and additionally fixes one real bug, a string in djmain.c was
malformed, it's curious it compiled.

Subject: Profiler related #2 (v2)
Hi, this a revised version of a patch I sent yesterday.
This one is much more cleaner, and the speed improvement is now significant
enough to come out of the profiling noise.
More over, this one compiles correctly... ;-)

mechanism; instead, you must access the sliders via the main menu. While in
the menu, you can use the ~ key to turn off the menu display and leave only
the bar display, in order to see more of the screen.
* removed redundant and unused definitions from header file
* renamed constants and functions to be MCS48* prefixed
* re-verified all opcode behaviors and timing
* changed illegal opcodes to count 1 cycle to avoid infinite loops
* changed EA behavior so that it is a push from the driver instead of a pull on each opcode fetch
(this may change further in the future).
* reimplemented IRQ generation and timer behavior according to documentation
* updated all drivers accordingly
* fixed several uses of PULSE_LINE, which no longer works
While this isn't 'free' as tilemap_set_palette_offset() is (when the offset changes, the pixmap cache needs to be invalidated), it helps removing some redundant code from drivers.
Updated snk.c and snk68.c to take advantage of the new function.
Register access is still performed using direct memory accesses,
but the pointers are fetched through the memory system. Now you can
see i8039 RAM in the debugger. Added internal memory maps of the
appropriate size so that drivers don't need to declare this RAM.
Added a number of variants from the MCS-48 family as it was not
clear which variants had what capabilities. All documented variants
now have internal memory maps for internal ROM and RAM. Removed
memory maps from drivers using embedded ROM/EPROM/OTPROM since
they are defined by the core now.
Added some initial logic to boot and run the PR-8210 ROM (i8049)
in ldplayer.c. Currently this is disabled behind a compile-time
switch. Once this is working, the plan is to incorporate this into
the existing PR-8210 emulation, but we're not there yet.
array is involved, it seems to think it is not a constant expression.
Added MDRV_DEVICE_CONFIG_DATA32_EXPLICIT() macro which takes an explicit
size and offset. Changed MDRV_DEVICE_CONFIG_DATA32() to be built off of
this macro. Added MDRV_DEVICE_CONFIG_DATA32_ARRAY() and
MDRV_DEVICE_CONFIG_DATA32_ARRAY_MEMBER() which do explicit computations
of the offset to work around MSVC's problems.
Replicated these changes for DATA64 and DATAPTR macros. Updated latch8.h
to use the new macros.
Added gun emulation for judge dredd.
Fixed judge dredd ide emulation when building with visual studio.
Mapped primal rage 2 inputs
Mapped player 3 & 4 inputs for 1 on 1 government, these are now the default with the 6 button inputs only mapped for games that need them.
Converted AT28C16 to a device.
Added preliminary support for devices to load/save nvram.
New games added or promoted from NOT_WORKING status

* renamed MDRV_LATCH8_MASK to MDRV_LATCH8_MASKOUT to clarify meaning
* Added MDRV_LATCH8_NOSYNC to specify which lines do not reed a cpu sync
* Updated drivers
The MDRV_LATCH8_NOSYNC is not used in dkong.c. All latches need synchronization
because at least one line does need a cpu synchronization.
8 bit latch interface and emulation
Generic emulation of 74LS174/175, 74LS259 and other latches.
Apart from providing synched latch operation, these
latches can be configured to read their input bitwise from other
devices as well and individual bits can be connected to
discrete nodes.
Please see audio/dkong.c for examples.

Before this patch a:
cpunum_set_input_line(5, ASSERT_LINE);
cpunum_set_input_line(3, ASSERT_LINE);
cpunum_set_input_line(3, CLEAR_LINE);
loses the state of line 5. This patch fixes it by adding an explicit
but optional "virtual irq line" support to the 68k interface.
Fix m68k interrupt handling by some drivers.
Clearing the NMI line to clear all the IRQ lines worked, but it just
doesn't make sense. Now that the irq lines are really independant,
the handling can be simplified.
Subject: Profiler related
Hi,
here is a smalll patch that :
- remove include "profiler.h" to files that do not use profiling function
* emu/machine/laserdsc.c
* osd/windows/video.c
- use PROFILER_USER2 instead of PROFILER_USER1 in mame/video/tx1.c
USER1 was used twice, USER3 once. I guess that USER1 should be used
only once and USER2 used in the 2nd place
- remove unused MACRO in emu/memory.c
Best regards,
Christophe JAILLET
Subject: Various cleanups
A couple of minor cleanups sitting on my disk for a while:
- removed obsolete ENABLE_DEBUGGER occurance
- removed more unprintable characters in SH-2 disassembler
- memset() usage cleanups
- removed duplicated TMS5110 entry in sound.mak
- use machine in uigfx.c where it's already available
This handler works for both disc-only games and those with overlays.
For disc-only games, the base macro is sufficient. For games with
overlays, an additional set of configuration macros are provided:
MDRV_LASERDISC_OVERLAY - specifies update function, width, height,
and bitmap format of the overlay
MDRV_LASERDISC_OVERLAY_CLIP - specifies the visible area of the
overlay bitmap
MDRV_LASERDISC_OVERLAY_POSITION - specifies default x,y position
MDRV_LASERDISC_OVERLAY_SCALE - specifies default x,y scale factors
The update function provided to MDRV_LASERDISC_OVERLAY is identical to
a normal VIDEO_UPDATE callback, so a standard one can be used. All
existing laserdisc drivers have been updated to support this new
rendering mechanism, removing much duplicated code.
Added the ability to configure the overlay position and scale
parameters at runtime. Added OSD menus to control them. Added logic
to save/restore the data in the game's configuration file.
Added new macros MDRV_LASERDISC_SCREEN_ADD_NTSC and _PAL, which
defines a standard screen with the correct video timing characteristics
and update function for laserdiscs. Updated all drivers to use these
macros instead of defining their own screens.
Added DISK_REGIONS to all laserdisc drivers.
Added DISK_IMAGE_READONLY_OPTIONAL to support games (like Cube Quest)
where the disk is non-essential to the game's operation.
Fixed bug in identifying the custom sound driver for the laserdisc.
Updated ldverify to identify blank regions of the disc for post-
processing.
Fixed rendering 16bpp with alpha using bilinear filters (fixes
screenshots of laserdisc games with overlays).
Included support for parsing .gdi files in chdman. [ElSemi]
Added new driver for Cube Quest. This includes CPU cores for the three
bitslice processors, as well as laserdisc support for the hacked
laserdisc that was used to drive the games.
[Philip Bennett, Joe Magiera, Warren Ondras]
Note that the SHA1/MD5 for the laserdisc will likely undergo at least
one more change before being finalized.
- Moved IRQ handling front-end into recompiled code
- Added TSTM/ANDM/XORM instructions
- Added SH-1 CPU support, including lower precision on MAC.W and locking out SH-2 only instructions
Subject: [patch] Collapse timer callbacks
Hi mamedev,
The following patch collapses timer callbacks in some cases to avoid
duplicating code. In the case of crystal.c, it also refactors two DMA
handlers and shuffles the init/reset code around a bit. I noticed
while doing this that h8_itu_read8 is missing cases 0x96,0x97 which is
almost certainly a bug, but I left it alone.

Subject: [patch] Fix i386 bsr implementation
Hi mamedev,
The i386 cpu emulator will return the wrong result for bsr when the
highest bit is set (0 instead of 15 or 31). The attached patch fixes
this.

ridgerac, ridgerab, ridgeraj, acedrvrw, victlapw: No sound in games
after reloading via the MAME UI
Hi mamedev,
The problem with namcos22 games losing sound when running multisession
is actually an m37710 cpu initialization bug. The attached patch
fixes it, and also collapses all the timer callbacks together as an
unrelated code cleanup.
Note: namcos22 has a lot of uninitialized state, so I wouldn't be
surprised if there are other multisession issues.
included by generic components in emu/ and thus should have no
dependencies on the MAME code.
Added new target ldplayer, which is based on MAME but serves as
a standalone laserdisc player for CHDs. Right now only the
Pioneer LD-V1000 is connected, and limited commands are available.
Each player type is a driver, so you specify the player type on
the command-line. The driver then opens the first CHD it finds
in your ROM path and uses that as the laserdisc. The intention is
that you specify the -rompath each time on the command-line, so
a typical approach might be:
ldplayer ldv1000 -rompath j:\mach3
where it will pick up the mach3.chd lurking in your j:\mach3
folder. Several basic commands are supported:
Space = play/pause
Alt = toggle frame display
Left = scan forward (when playing) or step forward (when paused)
Right = scan backward (when playing) or step backward (when paused)
0-9 = enter numbers for search
Enter = execute search to frame
item will be visible but not selectable.
Fixed bug that prevented the cheat engine from working when the
debugger was disabled.
Modified xmlfile.c to accept integer values in decimal or hex. The
default is decimal. Numbers may be prefixed by '#' for decimal
values, or by '$' or '0x' to indicate hexadecimal values. Also
added function xml_get_attribute_int_format() to return the format
of the attribute, so that it can be later replicated.
Updated cheat parser to preserve the format of attribute values
used for cheat parameters and items.
Added support for information-only cheat items, which will be
displayed in the menu but which are not selectable and have no
action associated with them. Empty information-only items are
automatically converted to menu separators.
The structures/names were getting too complex for my macros to handle. They would require hand editing and my computer is too slow to keep re-compiling.
Passes a clean compile.
Removed channels parameter from avcomp decode configuration.
Fixed incorrect test in winwork that led to spinning instead
of using the nicely allocated events we had on hand.
Forced a sound synchronization on each vsync in the laserdisc
playback. This prevents overwriting the tail end of the
buffer which was fouling up the MACH 3 audio decoding.
Removed obsolete size check for uncompressable audio data.
streams and a delta-RLE pre-encoding. Added optimized
case for the Y/Cb/Y/Cr video encoding case. Cleaned up
the code.
Updated avcomp.c to use the new huffman.c functions.
Reworked configuration options to allow for both input
and output of naturally aligned data streams. Updated
chdman and laserdsc to use the new interfaces. New
compression gives an additional 3-7% over previous
attempt and compresses the dummy CHDs down significantly.
I did not do much to the following files because I did not know the best way to name them.
aicadsp.h
sid.h
sidenvel.h
sidvoice.h
ymdeltat.h
I did not update structures only used in the src\emu\sound\*.c files. They are only used locally in the file so they were not worth the effort.
- Pass chip type around and restore Jarek's original behavior for YM2203/YM2610
- Always recalculate attack rate in set_ar_ksr, fixes Megadrive/Genesis "Batman & Robin"
What a PITA. :) I'll have to go back and do A-J to lower case the handlers to match the new structure names I already did.
Sorry Mess and other port developers, but the code should match what is stated on the official WIKI. But don't worry, I don't plan on updating anything but the sound cores.

memory regions. Extended error codes to report incorrect memory
spaces, memory names, or memory sizes. Added verification callback
to the debugger to validate CPU and memory region names, as well
as verifying that a requested address space exists for a given
CPU.
Added support for oneshot cheats (those with only an "on" script).
They are activated via UI_SELECT in the cheat menu, and pop up a
message when activated. Also added a "Reset All" item in the cheat
menu to reset all cheats back to their default state, and added
support for UI_SELECT on a non-oneshot cheat so that it resets that
cheat to its default value.
Restored previous behavior that allowed popmessage() messages to
overlay menus and other UI.

Subject: to simplify cischeat inputs
Hi,
the enclosed diff has a twofold effect on cischeat.c:
on one side: it adds diplocations to bigrun, scudhamm,
cischeat & f1gpstar
on the other side: it removes the current hacky handling of
f1gpstar coinage dips (check video/cischeat.c to see what I
mean with hacky!) to use conditional ports instead. BUT in
order to do this, I had to add more possible values for the
PORTCOND in iptport.c. The problem is that f1gpstar has a set
of coinage settings when you set the region to JPN or USA and
another one when you set the region to EUR or FRA. To implement
this I added the following self-explanatory new PORTCOND:
ISLARGER (>), ISNOTLARGER (<=), ISSMALLER (<), ISNOTSMALLER (<=).
Only two were really needed to implement f1gpstar dips, but
the other two seemed costless to me while offering even more
flexibility to the PORT_CONDITION macro.
Also notice that the handling of conditional ports in 'TAB>Dip
Switches' menu doesn't work well (in the current source, not
affected by my patch) with contracted expressions like
PORT_DIPUNKNOWN_DIPLOC: the wrong items remain listed in the
UI menu even when you change the condition! If you leave the
DEF_STR( Unknown ) with ON/OFF cases, everything is displayed
correctly in the menu. However, I was not able to track down
what part of code is responsible for this bug.

Subject: let's say goodbye to untagged input ports ;)
Hi,
enclosed please find a few patches against 126u3 source
* port01.diff -> port09.diff : these patches continues the
cleanup of inputs in drivers starting with C (the remaining ones),
D and E. No ambiguous situations this time, so I guess there should
be no problem with the changes. Improvements include conditional dips
added to dynduke and diplocations for chinagat, chqflag, circus,
citycon, cloak, contra and dynduke
* tag01.diff -> tag09.diff : these patches add tag to EVERY input port
in drivers starting with F->Z. Notice that only tags are added, no
AM_READ_PORT, nor PORT_INCLUDE (and I saw a lot of drivers would need
it ;) ), nor other cleanups contained in the patches above. I'll keep
cleaning input next week, probably, but at least we can definitely
remove the untagged version of PORT_START :) Notice I was able to
compile the source commenting out the definition of PORT_START, so
I guess every occurrence is covered...
- new tag <comment> (within <cheat>) is read and preserved
when saved
- removed variable attribute from <parameter>; it is now
assumed to be 'param'
- added default attribute for <parameter>
Added new variable 'frame' accessible from cheat scripts. This
can be used in the conditional to prevent execution on every
frame, or for other effects (like displaying temporary messages).
Added new variable 'argindex' which is the index when processing
an <argument> with a count attribute greater than 1. Can be used
in expressions like:
<argument count="3">main.pb@(1000+argindex)</argument>
Reinstated the cheat menu. It now displays all loaded cheats and
allows for them to be activated. All known cheat behaviors should
be working now.

tool which walks through either an AVI or CHD capture from a
laserdisc and ensures that there are no anomalies lurking in
the VBI data.
Added new option to chdman, where if you use -createav with
a special filename (either 2:2 or 3:2) it will create a fake
laserdisc files with the equivalent cadence. This can be used
for testing until full captures are available. Most games used
2:2 apart from Dragon's Lair and Space Ace, which were 3:2.
Note that even though these files are essentially blank, they
are Huffman-compressed, meaning that the maximum compression
ratio you will get is 8:1, so they still end up ~5GB.
Moved error strings from chdman.c to chd.c, where they can be
fetched from any caller via the new chd_error_string()
function.
Updated vbiparse to improve Manchester code decoding. It now
assigns a confidence level per bit based on how solid the
data is. Also added a new function vbi_parse_all which parses
the white flag and all three lines of metadata from a
laserdisc frame. It then compares line 17 and 18 against each
other and selects the most likely candidate based on per-bit
confidence and other factors.
Added frame number display to laserdsc.c. It is off by
default, though most players can be configured to turn it on
(not sure if any actually do). It can be manually toggled via
the backslash key during playback.
Commander (MACH 3 hardware). Old laserdisc hacks are now removed.
The code now talks to the standard Pioneer PR-8210 interface. Also
removed hacky "target list" from the MACH 3 ROMs; this information
is now decoded on the fly from the right channel laserdisc audio.
Other Gottlieb cleanups:
- moved sound inputs to audio/gottlieb and included them in
all relevant drivers
- ordered input ports and ROM definitions consistently
Other laserdisc changes:
- changed PR-8210 interface to work consistently for both Gottlieb
and Stern games
- added audio callback mechanism to allow drivers to peek at the
raw audio streams
- extended the VBI parser to be even more lenient
Instead, they are identified by the region they were loaded in. This
generally means one disk per region. get_disk_handle() now takes a
region name in place of an index. Updated all callers to do this.
The SCSI modules in particular posed a challenge to make this work,
so watch out for potential bugs there.
Changed the IDE interfaces to default to choosing the region with the
same tag as the device for its master disk (assuming no slave). Added
support for specifying explicit master/slave disk regions as part of
the configuration, though slave disks are still not supported yet.
Change the laserdisc interface to no longer require a disk number or
a custom sound device. Both are now assumed to be tagged the same as
the laserdisc device. Updated all drivers accordingly.
maps and behaviors according to the schematics. Hooked up coin
counters.
Added new functions cputag_set_input_line() to assert input lines
via CPU tag instead of index.
now simply requires an AVI file input.
Relaxed VBI Manchester code clocking to allow for a little bit
of wiggle when finding the clock.
Changed laserdisc support to parse white flags and other data
from the VBI data directly, rather than relying on the textual
metadata. Expanded video frame cache to 3. Changed the way
frames are assembled to decrease the likelihood of getting an
interlaced weave. Fixed sound creation so that it is done at
reset time instead of device start, when the sound devices aren't
yet live.
Fixed bug in winwork that caused the creation of single work
items to return NULL, and thus lead to massive memory leaks when
using A/V CHDs.
Removed the Enable line from the DISCRETE_ADJUSTMENT modules. They should never be disabled.
Some before/after speed tests:
dkong - from 203% to 204%
firetrk - from 418% to 429%
phoenix - from 253% to 257%
polaris - from 448% to 476%
to whole functions. The other one I'm not so sure about. Commented
code is usually hilighted differently, making it very easy to spot.)
Hi mamedev,
This set of patches has one aim only, to identify chunks of code that
have been disabled by the use of C/C++ comments, and to disable them
instead by using the preprocessor. The C comment approach to
disabling code isn't safe (embedded comments will trip it up), and the
C++ comment approach isn't elegant (you shouldn't need to touch every
line to disable a chunk of code). Using #if...#endif is preferable
always, excepting perhaps if (0) { ... }.
The patch has three parts. The first only handles cases where full
functions were disabled. The second handles cases where parts of
functions were disabled. The third then tries to restore the
whitespace that the use of comments converted from tabs to spaces via
srcclean.exe. It also cleans up the whitespace in a handful of the
files in areas outside of the original two patches.

- a few unnecessary checks after malloc_ort_die() calls
- changes two romload.c warnings to use GAMENOUN instead
- adds "deprecat.h" in a few src/mame/drivers files (would be

- cleans up the mame.mak by adding all missing defines and grouping
them based on cpu.mak
- renamed video_exit() to winvideo_exit() for consistency in function

accurate error reporting.
Removed old cheat.c/.h and replaced them with code that will read and
write the new XML-based cheat format using the new cheatpath option
(cheats still need to be enabled in order to load at all). Note that
the cheats are not implemented yet, but they are fully parsed. To test
saving, whenever a cheat file is successfully loaded, it is immediately
written back out as 'output.xml' to the cheat directory for validation.
The ROL/ROR/SHL/SHR opcodes provide the carry flags typically generated by
almost all CPUs. The RORC/ROLC opcdes map directly to the rotate through
carry of most CPUs as well.
auto-filled by the device manager before starting the device. This

Added new selector for device-specific ROM regions. Not yet wired
up in the ROM loader.

Subject: [patch] Stricter ADDRESS_MAP checks
Hi mamedev,
The current implementation of address maps is lacking some useful
checks of the initial tokens. In particular, it doesn't validate that
a particular entry doesn't try to define the same handler multiple
times.
The attached patch adds this and some other validations as fatalerrors
in address_map_detokenize, and fixes the affected maps. The errors
generally fall into the following categories.
1. AM_RAM AM_WRITE(...). Should have been AM_RAM_WRITE(...)
2. AM_RAM AM_READWRITE(...). The AM_RAM is a NOP.
3. AM_RAM AM_RAMBANK(...). The AM_RAM is a NOP.
4. AM_ROM AM_ROMBANK(...). The AM_ROM is a NOP.
5. AM_ROM AM_READ(...). The AM_ROM is a NOP.
One peculiar error was in equites.c, where there were two AM_BASE
entries.

second SH2 for ST-V games.
Fixed buffer overrun in latest SCSP code. Not sure how that ever
worked.
colmns97 still asserts in SCSPDSP, but this happened before the
region change.
integer value, regions are now referred to by a region class and
a region tag. The class specifies the type of region (one of CPU,
gfx, sound, user, disk, prom, pld) while the tag uniquely specifies
the region. This change required updating all the ROM region
definitions in the project to specify the class/tag instead of
region number.
Updated the core memory_region_* functions to accept a class/tag
pair. Added new memory_region_next() function to allow for iteration
over all memory regions of a given class. Added new function
memory_region_class_name() to return the name for a given CPU
memory region class.
Changed the auto-binding behavior of CPU regions. Previously, the
first CPU would auto-bind to REGION_CPU1 (that is, any ROM references
would automatically assume that they lived in the corresponding
region). Now, each CPU automatically binds to the RGNCLASS_CPU region
with the same tag as the CPU itself. This behavior required ensuring
that all previous REGION_CPU* regions were changed to RGNCLASS_CPU
with the same tag as the CPU.
Introduced a new auto-binding mechanism for sound cores. This works
similarly to the CPU binding. Each sound core that requires a memory
region now auto-binds to the RGNCLASS_SOUND with the same tag as the
sound core. In almost all cases, this allowed for the removal of the
explicit region item in the sound configuration, which in turn
allowed for many sound configurations to removed altogether.
Updated the expression engine's memory reference behavior. A recent
update expanded the scope of memory references to allow for referencing
data in non-active CPU spaces, in memory regions, and in EEPROMs.
However, this previous update required an index, which is no longer
appropriate for regions and will become increasingly less appropriate
for CPUs over time. Instead, a new syntax is supported, of the form:
"[tag.][space]size@addr", where 'tag' is an optional tag for the CPU
or memory region you wish to access, followed by a period as a
separator; 'space' is the memory address space or region class you
wish to access (p/d/i for program/data/I/O spaces; o for opcode space;
r for direct RAM; c/u/g/s for CPU/user/gfx/sound regions; e for
EEPROMs); and 'size' is the usual b/w/d/q for byte/word/dword/qword.
Cleaned up ROM definition flags and removed some ugly hacks that had
existed previously. Expanded to support up to 256 BIOSes. Updated
ROM_COPY to support specifying class/tag for the source region.
Updated the address map AM_REGION macro to support specifying a
class/tag for the region.
Updated debugger windows to display the CPU and region tags where
appropriate.
Updated -listxml to output region class and tag for each ROM entry.
- Fixed ADPCM decoder to remove bad optimization and match YMZ280B. DC offset is fixed and output quality is higher
- Improved handling of slot monitor and timers B and C
- Simplified interpolation code
- Rewrote core logic, communications, and interfaces.
- Added three parallel memory moves to the disassembler.
- Initial interrupt logic in place.
Plygonet.c updates.
- All communication hacks have been removed.
- Memory maps have been temporarily reverted while new DSP56k cpu core catches up.
Subject: [patch] Conditional code cleanup resubmit
Hi mamedev,
This is a resubmit of a previous patch. The earlier version would not
compile with 32-bit MSVC, due to the fact that its linker required
external dependencies in dead code to be met before dead code
elimination was done, causing linker errors. The proper fix for this
would be to add the necessary dependencies, so I instead simply left
the conditional code in place in winalloc.c and chd.c.
~aa
Original submission email below:
----
Conditionally compiled code tends to bitrot, so MAME should try to
avoid it as much as possible. I sent a patch six months ago to
eliminate conditional code associated with logging, here's another
patch that does more of this. Some notes:
1. drc_ops.c: I couldn't find a LOG_CODE anywhere, so I used if (0).
2. romload.c: I converted all the users of debugload to use
LOG((...)) instead, following the traditional conditional logging
pattern.
3. windows/sound.c: I eliminated the separate sound log and directed
the few outputs to the error log.

Subject: [patch] .data removals to fix reset/multisession bugs
Hi mamedev,
One nice artifact of properly constifying data structures in MAME is
that it makes it relatively easy to spot a class of reset/multisession
bugs, namely that almost any object in .data is probably in error.
Unless the value is properly initialized in a reset routine the
initial non-zero value can't be relied upon, so there's no need to
have a non-zero value to begin with.
With that in mind, here's a patch to move more items out of .data by
either applying const, removing the non-zero initializer (if its
overwritten by init/reset) or by adding appropriate initialization
code. In most cases I tried to add initialization code to a reset
routine, but in some cases I chose an init routine, possibly leaving a
reset bug intact.
Some interesting bits:
1. tms9900 core. The use of .data to initialize the irq_level wasn't
correct in some cases as the layout of the structure was core
dependent.
2. bfcobra.c. By introducing a VIDEO_START routine a hack in
VIDEO_UPDATE could be removed.

convert between attotimes and a clock tick at an integral frequency.
Changed the 6532 RIOT device into a proper device. Rewrote the
logic to be simpler and leverage the new attotime functions. Changed
the I/O port setters to specify a mask, and changed the I/O port
callbacks to pass in the previous value. Updated tourtabl and
gameplan drivers to use the new device interface.
Converted audio/starwars.c, audio/exidy.c, and audio/gottlieb.c to
use the new RIOT implementation instead of rolling their own.
Began gottlieb.c cleanup. Converted palette calculations to resistor
weights. Corrected video timing. Reduced the number of separate
machine drivers. Fixed incorrect spriteram sizes. Populated full
memory maps for the main CPU and the rev 1 sound board. More to
come.
- Rearranged decoding behavior.
- Updated code style to MAME standards.
- Tested each single-word opcode with custom ROMs.
(This is a precursor to other major dsp56k changes I have made. I just gotta' get plygonet commanders up and running to do some tests)
- TGP now correctly uses table roms (model1/2 updated accordingly)
- removed FIFO hack on srallyc (game now runs)
- added analog ports reading for model 2A/B/C
- fixed some loading instructions in the TGP. that fixes srallyc automatic transmission bug
Added validity checks to ensure no duplicate sound or CPU tags.
Fixed several duplicate sound tags from the last checkin.
-listxml now outputs the tag names for CPUs and sound chips.
well, the fix is not that but changing them this way:
program_write_dword_32le(i960.r[I960_FP]-16, i960.PC);
program_write_dword_32le(i960.r[I960_FP]-12, i960.AC);
in take_interrupt.
It seems it came from a partial fix in the ret instruction. the manual says that PC is saved at FP-16 and AC at FP-12
it was reversed in mame, so when trying to fix it, i suppose Ernesto forgot to change the push too.
I've tested this fix and apart from having daytona working, pilot kids 2A works too (that I think has been broken for ages).
MDRV_SOUND_ADD. All sound chips must now include a tag.
Laboriously changed all existing drivers to define a
unique tag for each sound chip.
CPUs are next, but will require a more hands-on manual
process to produce reasonable tags.
properly ignore the "break into debugger" keypress and not allow
related characters to filter through. Removed some hacks related to
making that work in the past.
Changed osd_wait_for_debugger() to take a machine parameter and a
"firsttime" parameter, which is set to 1 the first time the function
is called after a break. The Windows debugger uses this to ensure
that the debugger has focus when you break into it.
EEPROM data, and the size is in terms of units, not bytes. Updated all
drivers accordingly.
Changed the ROM loading code to actually alter the region flags based
on the CPU endianness and bus width when creating the region, rather
than fixing them up on the fly. This means that callers to
memory_region_flags() will get the correct results.
Changed the expression engine to use two callbacks for read/write rather
than relying on externally defined functions.
Expanded memory access support in the expression engine. Memory accesses
can now be specified as [space][num]<size>@<address>. 'space' can be
one of the following:
p = program address space of CPU #num (default)
d = data address space of CPU #num
i = I/O address space of CPU #num
o = opcode address space of CPU #num (R/W access to decrypted opcodes)
r = direct RAM space of CPU #num (always allows writes, even for ROM)
e = EEPROM index #num
c = direct REGION_CPU#num access
u = direct REGION_USER#num access
g = direct REGION_GFX#num access
s = direct REGION_SOUND#num access
The 'num' field is optional for p/d/i/o/r, where is defaults to the
current CPU, and for e, where it defaults to EEPROM #0. 'num' is required
for all region-related prefixes. Some examples:
w@curpc = word at 'curpc' in the active CPU's program address space
dd@0 = dword at 0x0 in the active CPU's data address space
r2b@100 = byte at 0x100 from a RAM/ROM region in CPU #2's program space
ew@7f = word from EEPROM address 0x7f
u2q@40 = qword from REGION_USER2, offset 0x40
The 'size' field is always required, and can be b/w/d/q for byte, word,
dword, and qword accesses.
- All games on all drivers should work as before except "colmns97" and "stress" which crash due to sound system trouble.
- All idle skips are still included. They are quite a bit less effective than they were on the interpreter, but they still give a boost.
- Fast RAM bypass is not included yet so this does not represent final performance. That said, it's consistently faster than the interpreter even now. Example: sfiii3 on 0.126 gets 609% on the interpreter and 961% on the DRC.
Major thanks to Aaron for his assistance with several sticky core bugs and other issues encountered writing this.

Added new module uiinput.c which manages input for the user interface.
The OSD is responsible for pushing mouse events and character events
to this interface in order to support mouse movement and text-based
input (currently only used for the select game menu). Added support
for navigating through the menus using the mouse.
[Nathan Woods, Aaron Giles]
Redesigned the UI menus so that they can maintain a richer state. Now
the menus can be generated once and reused, rather than requiring them
to be regenerated on each frame. All menus also share a comment eventing
system and navigation through them is managed centrally. Rewrote all the
menus to use the new system, apart from the cheat menus, which are now
disabled. Reorganized the video menu to make it easier to understand.

- Roll back older periodic function
Now standard/old format work in this function
Otherwords, several operations which doesn't exist in older

And added new cheat options, "Load New/Standard/Old Format Code"
(Default : load all format codes)
NOTE : delete all cheat options in the database before start
or reload default options (Shift + Reload key)

- Added format strings structure to accept huge size strings
in loading a database to prevent from breaking other strings
- Changed Link in new format
Label code is now "Link-Label" and sub-label is "Label-Sub-Link"
"Standard-Link" is no longer label
- Added choose_label_index() to manage label selection
- Fixed build_label_index_table() to prevent from crashing

* fixed swxc1, sdxc1 to use the correct source register (fixes many Gauntlet problems)
* fixed CCR31 display in debugger
* fixes assert: src/emu/video.c:664: visarea->min_x < width

macro from the source code. All MAME builds now include
the debugger, and it is enabled/disabled exclusively by
the runtime command-line/ini settings. This is a minor
speed hit for now, but will be further optimized going
forward.
Changed the 'd' suffix in the makefile to apply to DEBUG
builds (versus DEBUGGER builds as it did before).
Changed machine->debug_mode to machine->debug_flags.
These flags now indicate several things, such as whether
debugging is enabled, whether CPU cores should call the
debugger on each instruction, and whether there are live
watchpoints on each address space.
Redesigned a significant portion of debugcpu.c around
the concept of maintaining these flags globally and a
similar, more complete set of flags internally for each
CPU. All previous functionality should work as designed
but should be more robust and faster to work with.
Added new debugger hooks for starting/stopping CPU
execution. This allows the debugger to decide whether
or not a given CPU needs to call the debugger on each
instruction during the coming timeslice.
Added new debugger hook for reporting exceptions.
Proper exception breakpoints are not yet implemented.
Added new module debugger.c which is where global
debugger functions live.

- Added new cheat options, "Vertical/Horizontal Key Repeat Speed"
NOTE : delete all cheat options in the database before start
or reload default options (Shift + Reload key)

Subject: [patch] memory_region madness reloaded
Hi mamedev,
The memory_region and memory_region_length functions are probably the
two most common functions in MAME that don't take a machine parameter
but should given the syntax of the related apis memory_region_type and
memory_region_flags. Clearly they didn't get the parameter because of
the sheer number of changes needed to change the apis. This pair of
patches makes the change, and deals with the consequences.
The second patch then changes the api for memory_region and
memory_region_length, and fixes the fallout. It generally plumbs
through machine parameters where needed, except for the case of sound
apis which I deferred doing so till later. This increased the number
of deprecat.h includes by ~50. Given it is a massive patch, there are
bound to be a few mistakes in it (I had to make ~20% of the changes by
hand), but I exercised care and reviewed the patch several times to
minimize the problems.

input ports.
- reactivated back-end validation mechanism
- added back-end validation for ADD/SUB/MUL/DIV/CMP forms
- fixed several errors in dealing with more obscure flag combinations
on a command-line parameter and the configuration. Changed Windows OSD
code to use this instead of its own logic. Changed -snapview to share the
logic as well, enabling 'auto' as a -snapview option.
Enabled by default for snapshots and movie rendering.
Added new option: -snapsize, which lets you specify the target
resolution for snapshots and movies. The existing behavior is still
the default: create snapshots and movies at native pixel
resolutions.
Added new option: -snapview, which lets you specify a particular
view to use for rendering snapshots and movies. The existing
behavior is still the default: use a special internal view and
render each screen to its own snapshot in its own file. When using
this option to specify a view other than 'internal', only a single
snapshot file will be produced regardless of how many screens the
game has.
Improved AVI and MNG recording to properly duplicate/skip frames
as appropriate to keep the correct framerate.

* Added CBit (Condition Bit). This checks bit in read data then
set or clear bit in case of true.
* Rearranged cheat code viwer based on newest cheat format
- Fixed unworking Load Old Format option. If you want to load old or
older format code, set it (default is OFF)
- Renamed functions/structures based on coding guidlines
All structures and included parameters are completed
- Merged resize_*_no_dispose() into resize_*()
- Removed the hack of search region for SH-2 CPU because required
region is now set as expected without this hack
Subject: [patch] memory_region madness
The memory_region and memory_region_length functions are probably the
two most common functions in MAME that don't take a machine parameter
but probably should given the direction MAME has been going in
removing global variable references. Attached are massive patches to
accomplish this. I wish they could be smaller, but sadly, this is
butchery, not brain surgery.
The first patch makes some simplifications to help the second patch
along. It is a general improvement as well, and hopefully can be
applied even if the second patch is rejected. Specifically:
1. Introduced/updated some include files for files that export
functions whose apis will need to be changed (cps1.h, decocrpt.h,
ms32.h, pgm.h, fd1089.h, konami1.h). In the case of konami.c, I
renamed the file konami1.c and changed the api and callers to only
require one function export.
2. Pulled memory_region*() calls out of for loops and folded the
occasional duplicated call. The compiler can't likely infer that the
results are constant, so this should be a minor performance win as
well.
- rewrote PowerPC implementation as a dynamic recompiler on top
of the universal recompiler engine
- wrote a front-end to analyze PowerPC code paths and register usage
- wrote a common shared module with C implementations of tricky
CPU behaviors
- added separate CPU types for the variants supported, instead of
relying on a hidden model enum
- rewrote the serial port emulation for the 4xx series to be more
accurate and not rely on separate DMA handlers
- rewrote the MMU handling to implement a software TLB that faults
in pages and handles changed bits appropriately
- implemented emulation of the PowerPC 603's software TLB, which
allows the model 3 games to run without a hack to disable the MMU
Updated the PowerPC disassembler to share constants with the rest of
the core, and to more aggressively use simplified mnemonics, especially
for branches. [Aaron Giles]

1. In the MIPS core:
- renamed struct mips3_config -> mips3_config
- updated all drivers to the new names
- removed MIPS3DRC_STRICT_COP0 flag, which is no longer used
- a few minor cleanups
2. In the CPU interface:

duplicate bits. There are a lot of these!
Updated initialization code to print errors and fatal only if the input
ports were unable to be constructed at all.
Typedef'ed a real eeprom_interface structure.
Added a PORT_CUSTOM for the eeprom bit reading. Updated several
drivers to use that by specifying it in their input ports instead
of having a custom read handler that inserted the bit forcefully.
Added a PORT_CUSTOM for the ticket dispenser callback as well.
Updated the dcheese driver to use it.
Many more drivers can be updated to use these new PORT_CUSTOMs
in the future, eliminating hacky input port read handlers.
mode DIPs on the top of the menu
Fixed behavior of toggle switches so that they don't lose their value
when the UI is up. They also can now be used for multibit DIP switch
settings in which case they toggle through all the options.
New functions input_field_select_next_setting() and
input_field_select_previous_setting() which can be used to iterate
properly through DIP switches. Fixed the behavior for cases where
conditional ports are in play (you could get stuck). Changed uimenu.c
to call these instead of implementing its own.
Changed uimenu.c so that hitting ENTER on a DIP switch resets it to
its default value. This is analagous to how the OSD sliders behave.
- Reworked the color routines switching to resnet system.
- Added a resistor network diagram.
- Switch to pre-defined crystal value.
- Changed the WATCHDOG_TIME_INIT to be based on miliseconds instead of hertz.
- Other minor cleanup/fixes.
- Updated technical notes.
Subject: [patch] Missed Machine->machine changes
Hi mamedev,
A short incremental to my last deprecat.h patches. This one is the
result of a slightly improved fixup script, which finds more cases
where Machine can be replaced with machine. Six more files lose
deprecat.h.
~aa
Subject: [patch] More Machine->machine changes, add machine to irq
callbacks
Hi mamedev,
Here are two more patches to eliminate Machine globals. The first
patch was autogenerated by the attached fixup script. That script has
been updated to catch additional cases which it previously missed
(when Machine is the last parameter to a function or Machine is used
in an assignment). This makes ~50 more files deprecat.h free.
A sizable chunk (~20%) of the remaining uses of the Machine global in
the drivers are due to irq callbacks for sound and machine updates.
Typically such callbacks need to call cpunum_set_input_line, which
requires a machine parameter, so if the callbacks don't pass the
machine parameter, these routines have no choice but to reference the
global variable.
The second patch attempts to address most cases of this by adding the
machine parameter to the callback interfaces. This allows us to
remove #include "deprecat.h" from ~150 files, at the cost of having to
fix up hundreds of callbacks.
In total, these patches reduced the number of files with deprecat.h
from 783 to 575.

Subject: saturn CPU patch
Dear MAMEDev,
The attached patch corrects several bugs in the emulation of the saturn
CPU. These corrections are needed to make new HP48 drivers (to be
submitted to MESS imminently) work.
AFAIK, MESS is the only place where this CPU is used, so, the patch
should
not cause any regression in MAME.
The patch is against 0125u1.
Best regards,

Antoine Mine
* Added new opcode LZCNT which returns the number of leading zeros in
a parameter.
* Added new opcode XTRACT which is a combined rotate/mask (basically
rlwinm from PowerPC)
* Added new opcode INSERT which is a combined rotate/mask/blend
(basically rlwimi from PowerPC). Best. Opcode. Ever.
* Updated all back-ends to support these new opcodes.
* Fixed several bugs relating to shifts/rotates and optimizing out
cases incorrectly.
MIPS3 DRC changes:
* Updated to use INSERT and XTRACT where appropriate
* Cleaned up register usage to enable an additional direct mapping;
this means Linux gets 1 now and Windows gets 3
machine registers if the machine supports it. Currently only x64 on
Windows has enough free registers to do so, though PowerPC will almost
certainly be able to take advantage of this. Gives a minor speedup.
* Fixed front-end so that virtual no-op instructions are still targeted
as branch targets.
* Fixed front-end to mark the beginning of each sequence as needing TLB
validation, since any sequence can be jumped to from anywhere.
* Redid the MIPS3 TLB implementation. Fixed the exception vector and
type handling. Changed the bitfields to directly map from the MIPS TLB
format. Added distinction between TLB fill and TLB valid/modified
exceptions.
* Added separate modes for user, supervisor, and kernel modes. Each mode
does proper verification of addresses now and generates address errors
for invalid accesses.
* Fixed several bugs in the TLB implementation; not everything works
yet but it's a lot closer.
* Made COP0 access checking mandatory in non-kernel modes.
* Fixed several crashes when recompiling virtual no-ops.
* Fixed TLB bug where entries for virtual address 0 were present by
default.
* Fixed bug in the map variable implementation that would sometimes
result in incorrectly recovered values.
This will be expanded in the future.
Added two new opcodes: SAVE and RESTORE to save and restore the entire
virtual machine state for examination/setup.
Added new back-end function get_info() which returns information from
the back-end about how many actual registers will be mapped.
Fixed a bug that mapped the high a low parts of registers to the same
address. This should help the C back-end run better on big-endian
architectures.
* Input ports are now maintained hierarchically. At the top
level are input ports, which contain a list of fields. Each
field represents one or more bits of the port. Certain fields
such as DIP switches and configuration switches contain a
list of settings, which can be selected. DIP switch fields
can also contain a list of DIP switch locations.
* Normalized behavior of port overrides (via PORT_INCLUDE or
by defining multiple overlapping bits). All fields within a
port are kept in strict increasing bit order, so altered DIP
switches are now kept in the appropriate order. This addresses
MAMETesters bug 01671.
* Live port state is now fully separate from configured
state. This is manifested in a similar way to devices, where
a const list of ports can be managed either offline or live.
Each port has a pointer to an opaque set of live state which
is NULL when offline or valid when live. Each port also has
a running_machine * which is also NULL when offline.
* Because of this new arrangement, the conversion from tokens
to a list of ports now requires reasonably complex memory
allocation, so these port lists must be explicitly allocated
and freed (they are not mantained by automatic resource
allocation).
* Custom and changed callbacks now take a pointer to a field
config instead of a running machine. This provides more
information about what field triggered the change notification.
The machine can be found by referenced field->port->machine.
* The inptport.c module has been cleaned up and many
ambiguities resolved. Most of this is internal, though it did
result in osd_customize_inputport_list() being changed to
osd_customize_input_type_list(). The parameter to this function
is now a linked list instead of an array, and the structures
referenced have been reorganized somewhat.
* Updated config.c to pass machine parameters to its callbacks.
* Updated validity checks, XML output, and UI system to handle
the new structures.
* Moved large table of default input settings to a separate
include file inpttype.h.
* Removed gross hacks in trackfld and hyperspt NVRAM. These
may be broken as a result.
Subject: [patch] Remove opbase globals from the public interface
Hi mamedev,
There are several variables associated with opbase handling which are
global and documented in memory.h and thus their use is not well
controlled. This patch attempts to remedy this. Because they are
used in various inline memory functions, they can't yet be made local
to memory.c, but by rescoping their declaration they can be hidden,
much like we hide totalcpu.
Most of the uses are in OPBASE_HANDLER() macros, so by encapsulating
the opbase state into a struct and adding that to the handler
interface those can be converted to local variable manipulation. There
is one use in missile.c in a MACHINE_START that I simply removed, it
shouldn't be needed.
One side effect of this patch is that the various unsafe memory macros
can't be used directly, they will be a compiler error now. That is
probably for the best.

to write RGB bitmaps. Unfortunately, the only option is fully
uncompressed, which means the resulting AVIs are *HUGE* and
may not play correctly in realtime due to high data rate. The
intention is that these uncompressed AVIs are post-processed
by other utilities to compress the video and produce a
realtime playable result.
Added new command-line option -aviwrite which works just like
-mngwrite, except it produces AVIs and streams sound to them.
Updated documentation accordingly.
Shift+F12 still produces MNGs for now, though this might change
in the future.
Modified fileio.c to retain the full pathname to the file so
that it can be queried while the file is open.
is drcuml.c, which defines a universal machine language
syntax that can be generated by a frontend recompiler and
then retargeted via a generic backend interface to any of
a number of different architectures. A disassembler for the
UML is also included to allow examination of the generated
UML code.
Currently supported backend architectures include 32-bit x86,
64-bit x86, and a platform-neutral interpreted C backend that
can be used as a fallback for platforms without native
support. The C backend also performs additional validation
to ensure assumptions are met.
Along with the new architecture is a new MIPS III/IV
recompiler frontend. This frontend has been rewritten from
the old x64-specific recompiler to generate UML opcodes
instead. This means that the single recompiler can be used
to target multiple backend architectures and should in
theory produce identical results across all of them.
The old 32-bit and 64-bit MIPS recompilers are now officially
retired. The new system provides similar performance (within
5% generally) to the old system and has similar compatibility.
The only currently known issues are some problems with the
two Gauntlet 3D games.

Subject: [patch] Small deprecat.h related cleanup
Hi mamedev,
While doing some work on eliminating some uses of deprecat.h, I came
across a few files that didn't have it that used deprecated features.
A little investigation revealed they were getting it through
debugger.h, typically by referencing m68000.h. Since deprecat.h is
intended to document the files that need updating (otherwise it would
just be included in a common header), I reworked debugger.h to not
import it when the debugger is not enabled, and fixed the files that
broke as a result.
~aa
Subject: [patch] Remove more Machine globals, #include "deprecat.h"
Hi mamedev,
The attached patch goes through and converts a number of Machine
globals to machine locals, and then removes #include "deprecat.h" if
appropriate. The script that generated it is included, since the
patch itself is rather large and would have been time consuming to
produce otherwise.
The script doesn't convert cases of Machine that aren't in common
macros. I'll try to tackle those later if someone doesn't beat me to
it.

Subject: [patch] Eliminate assignments in conditionals
Hi mamedev,
Assignments in conditionals are never really needed in C and are
occasionally just plain bugs (== gets typed as =). As such, it would
be good to remove these from MAME so that compilers that warn on this
construct can flag the likely bugs (MSVC does this for example). The
attached patch does just that. In addition, it refactors some
repeated code which had this in taito_f3.c into a couple macros. Using
inline functions would unfortunately have required more significant
changes, perhaps I'll tackle that another day.

Hi mamedev,
This small patch makes specifying an invalid bios a fatalerror and
removes the need to expose system_bios to the drivers by reworking the

words, it removes an ugly hack). This should resolve bug 00149,
although I did not implement the popmessage as suggested.

IMPORTANT: masks that are passed to the _masked_* functions are

Added ability to test the instruction/data cache ram. The scratchpad and BIU register are now handled internally to the CPU.
All writes are performed with masks. SWL/SWR used to be implemented with two writes ( one byte and one word ) when writing three bytes, now it only ever performs one. Byte and Word writes use masks as they leave the rest of the register on the bus, which can be picked up by larger registers.
The read/write functions to use are cached when the SR bits are updated, as are the bad address masks.
Added coprocessor 1 & 3 support, though they don't do anything useful.
All loads now go through the delay pipeline, a lwl/lwr will grab the value out of the pipeline if it's updating the same register.
Added undocumented behaviour of BLEZ/BGTZ. The comparison for zero can be changed by specifying an alternate register in the RT field ( the documentation says you should always use register 0 ).
Restricted to 16 COP0 registers & generate an exception if any of the 5 for the MMU are used.
Added BCF/BCT instructions, although I have found no conditions that affect them yet.
Generates an exception if any MMU instructions are executed.
Sets the CE instruction for all exceptions, not just those involving a coprocessor. The bits of the opcode that specify the coprocessor are grabbed no matter what the instruction.
Added TAR register and BT bit in SR. When an exception occurs during a branch, BT determines whether it was taken or not. The TAR register gets set to the destination of the branch.
Fixed the BD bit when you are in a branch delay slot and you didn't take the branch, this shows up in the pipeline as !pc.
Fixed branches within a branch delay slot.
Multiply & divide instructions can be aborted if you write to HI/LO before reading the result.
Added data breakpoints, you don't appear to be able to set breakpoints on any of the addresses internal to the CPU.
Multiply/divide/GTE instructions can execute when an exception is taken, although the EPC indicates that it hasn't. The BIOS avoids rerunning GTE instructions as they are destructive, so you have to make sure they run.
Added bus error handling, PSXCPU is limited to 8mb of ram & any access outside this range will trigger an exception. I believe this is to be an internal limit.
Added CXD8611R as a specific CPU type, System 12 appears to allow more than 8mb of ram & it's possible that this is different.
Mapped out all instructions to either generate an exception or ignore bits.
Updated the disassembler to match the decoding.
Fixed disassembling of branch instructions in a branch delay slot.
Lui checks for a ori/addiu following and will show you the result.
Added step over/out support.
Fixed standalone disassembler.
Rewrote INP recording from scratch, since all old INPs are broken anyways.
Header now includes timestamp, which overrides the default time base for MAME's system time.
Each frame recorded now gets a timestamp.
Analog ports are recorded once per frame and interpolated.
Analog port calculations are all done in fixed point for consistent results.
A bunch of other minor tweaks in the input port code.
There may still be a few changes to the final INP format (considering adding
NVRAM data directly in the INP file, for example....) but this at least seems
to work for the games I've tried.
All custom itemids were mapped to class SWITCH. With the recent modification, this implicitly changed to ABSOLUTE.
This fix will use the passed itemid to determine the class.

easier to use I've also created a src/emu/devconv.h in the same style
as src/emu/memconv.h.
I do not have all roms/disk images to test all drivers. I have only
been able to test pf2012, filetto, and topgunnr.
Subject: Further ACIA changes
Added dynamic control of RX and TX pins to 6850 ACIA emulation - this is
needed for correct operation of the MPU4 Video communications system,
and may be handy for some MESS systems. To use, set the rx and tx clocks
to 0 in the acia interface, then use acia_tx_clock_in() and
acia_rx_clock_in() respectively.
Subject: small change for MESS cleanup
This adds the "Machine" parameter to a MESS function call in MAME
code to go along with Machine -> machine ckeanups in MESS
Subject: Machine -> machine cleanups
This patch changes "Machine" to "machine", when the runnin-machine
parameter is already available. In some cases I could even remove the
dprecat.h.
I will look for some occurances where it can be easily changed and
afterward take a step at adding the running_machine parameter in a
few places.
* Fix timing of stream_update in discrete_sound_w
All sound cores update before processing changed data
* Add streeam_update to discrete_sound_r
* Now supports multiple output nodes per module.
There is the possibility to support multiple outputs per module.
In this case, NODE_XXX is the default output. Alternative outputs may
be accessed by using NODE_XXX_YY where 00<Y<08.
You may also access nodes with macros:
NODE_XXX = NODE_SUB(XXX, 0)
NODE_XXX = NODE(XXX)
NODE_XXX_YY = NODE_SUB(XXX, YY) with YY != 00
This should e.g. make discrete sound emulation easier
when dealing with e.g. flip flops (Q & QQ) and binary counters
* added sanity checks to check consistency issues introduced by this change
* modules specify number of outputs ==> Certain special modules (WAVELOG)
may no longer be used as input nodes
* removed explicit (NODE_XX + expr) from a couple of drivers
All occurrences of ACCESSING_LSB, ACCESSING_MSB, ACCESSING_LSB16, ACCESSING_MSB16, ACCESSING_LSB32, ACCESSING_MSB32, ACCESSING_LSW32, ACCESSING_MSW32 & simple mem_mask checks have been replace with the new macros.
The old macros are gone.
* Give us a Break [2 sets]
* Ten Up [2 sets]
Neither are playable; they don't register coins for some reason.
2. Fixed interrupt handling and 16-bit memory accessors in 6840ptm.c
Also cleaned up code for the sake of readability.
3. JPM games now have their own object archive file.
- implemented serial input/output
- fixed XAD/LDD, XIS1, RMB3 opcodes
- fixed clock divider
- fixed internal memory map size
- added some cpu variants
As a result, Draco at least initializes the AY-8910 now.
* itemclass now part of token if item is not found
Settings for joysticks which use a custom item id will still be lost. A fallback has to be provided here since those will use a token generated from the input item name.
Subject: Unnecessary assert in video.c
The assert
assert(machine->config->devicelist != NULL);
in video.c causes the MESS mk1 driver to fail because it doesn't have
any devices - no screens and no sound devices. It works fine when the
assert is removed.

Subject: SH-4 debugger output fix
This patch fixes "garbage" (newlines) in the debugger window when
debugging the SH-4 CPU.
It also conatins a small comment fix in video/playch10.c and the
removal of some yet unused or just obsolete macros in emu/cpuint.h.
a NULL list head (in which case you have an empty device list). All the
code works fine with a NULL head and returns appropriate values. Removed
changes to video_screen_count() and video_screen_first() which were added
to work around this behavior.
or not the VIDEO_UPDATE was called as a result.
Modified amiga.c to use this information so that we guarantee a call
to amiga_render_scanline() regardless of the video state.
Fixes 01521: ar_sdwr: Game hangs on title screen
This is still WIP bug I've been working on it for sveral weeks and I want to get it out before leaving for holidays.

- major cleanup of the mess in equites.c:
- many thanks to Corrado Tomaselli for precious hardware info.
- implemented bg perspective scrolling using PROMs
- fixed sprite flip & disable
- fixed bg color
- converted bg to tilemaps

- mametesters bugs fixed:
- 00217 splndrbt: On boot the pcb displays a clean light blu screen while in mame there is a black road.
- 00220 splndrbt: Concerning the gfx, on the pcb the background is not linear as shown in mame.
- 00223 splndrbt: On the first level when you pass the asteroid belt the star road should be light blue instead of black like mam
- fixed champbas inputs
- merged talbot with champbas, some driver clenaup
- fixed shougi inputs
- switched exctsccb to use the correct gfx ROMs (matches screenshot found in 01058 exctsccb: Exciting soccer bootleg should be placed in champbas.c.)
- fixed sprite bpp in exctscrr, removed the horrible hacks that were used to fix colors and transparency.
- fixed sound clipping in exctsccr
refresh information from the device's inline_config, since this is
done before the screen devices are start. Fixes 01491: switchres
causes Exception at EIP=009413BF: ACCESS VIOLATION.
Also, fixed render_target_get_minimum_size() to return nominal values
if no screens are found.
Added DEVINFO_INT_TOKEN_BYTES, which is queried before device
startup. It should return the size of the structure that will
be hung off of device->token. It must not return 0.
Changed the core device interface to allocate and zero a block
of memory the size of DEVINFO_INT_TOKEN_BYTES before calling
device_start. The pointer to this memory is already attached
to device->token at the time device_start is called.
The primary motivation for this is to allow the device_start
function to make internal calls and pass the device_config *
around as if the object were fully constructed. Since the token
is used to indicate whether or not a device is live, this makes
the device "live" at the time device_start is called rather
than after it completes.
I applied the same fix to verifyroms. Now a status message is printed for every sample/ROM set regardless if an individual or all the sets are audited.
My fix is a bit heavy handed. The real access violation happens in update_digital_joysticks() after the comment "read all the associated ports" and before the next comment
Converted Centipede, as an example.
To define a scanline timer, use something like this:
MDRV_TIMER_ADD("32V", SCANLINE, generate_interrupt)
MDRV_TIMER_SCANLINE("main", 0, 16)
The first number is the first scanline the timer will fire on, the 2nd number is the increment.
So in this case, the timer will fire on 0, 16, 32, ..., 224, 240, then wrap around
because the screen is defined as 256 lines high.
The current scanline is passed to the callback in its 'param' argument
Subject: small fix to cpu.mak
Attached please find a small patch to include M68000 CPU only when you're
compiling a build with the M68K. this is needed to e.g. compile tiny
builds .
Subject: patch for SVP (Sega Virtua Processor) emulation
hello,
this patch adds support for Sega Virtua Processor, to run
Genesis/MegaDrive version of Virtua Racing, intended to be used by
MESS. It consists of a CPU core SSP1601, and updates in megadriv.c:
* SSP1601 replaces SSP1610, as it has been confirmed by Stiletto and
other sources that SVP actually contains SSP1601. The current SSP1610
is placeholder only (nearly completely unimplemented) anyway.
* Changes in megadriv.c add a new driver for Genesis/MegaDrive+SVP
combination, also add SVP memory controller logic and memory map.
The diff has already been reviewed by Reip and SSP1610 removal was one
of his suggestions (SSP1610 is not used by any drivers).
Attached is update for Merit hardware based on V9938 (CRT-250 and CRT-260 - meritm.c).
New playable games:
Pit Boss II
Super Pit Boss
Pit Boss Megastar
Megatouch IV
Megatouch IV Tournament Edition
Megatouch 6
Changed slapstic management to always install an opbase handler to more
aggressively catch code executing in the slapstic region. Updated all
drivers to separate the slapstic region of ROM into a different ROM
section from the fixed ROM.
Changed input ports to register a frame callback, which is
called immediately after throttling and updating. This is the
proper "sync point" between emulated time and real time. Moved
all analog and digital port processing into a central place
here. Added tracking of time since the previous frame update
and use that as an estimate for the time of the current frame.
This is used to scale analog ports without the use of
cpu_scalebyfcount(). This is not perfect in the case where
frame rates are dynamic (vector games), but works well for
other cases.
Further cleanup of memory header and code.
- Added video_screen_auto_bitmap_alloc(screen) -- it is just a shorthand for
auto_bitmap_alloc(video_screen_get_width(screen), video_screen_get_height(screen), video_screen_get_format(screen))
which is a common operation
- The Dynax/Don Den Lover games now do their updating in VIDEO_UPDATE instead of VIDEO_EOF. This semmed to
have fixed the palette problems
- Went through some of these drivers and changed Machine to machine
