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,
CPU_EXECUTE, along with macros for the name and for calling, in the
spirit of the devintrf.h macros. More will come later.
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.
Updated all CPU cores to the new macros and parameters.
Note that this changes the way we "pointer"-ify cores. I'll send an
update shortly.
Began the process of pruning options from the 68000 core, hard-coding it
for MAME's needs. We've hacked on it sufficiently that it is no longer
generic, so this is a good opportunity to simplify the code so that it
can actually be followed.
means of setting the minimum useful scheduling quantum, and clamping
all quanta to that value.
Changed interleave/boost handling to use scheduling quanta instead
of timers.
Added machine parameter to cpu_boost_interleave.
Updated cpuexec to compute the "perfect" interleave value taking into
account the minimum number of cycles per instruction specified by the
CPU core. Updated Z80 core to indicate that the minimum cpi is 2. Fixed
incorrect minimum cpi in the 68020+ cores.
Simplified a bit of logic in cpuexec_timeslice.

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.

* prefetch timing now also used by V20 and V33
* moved some static variables into cpu context
* nec_reset now explicitly clears context variables
* all cpus now share nec_execute

* The whole startup cycle now works. No more timeouts and erratic behavior.
* lohtb2 will however not display the "Warning" screen due to a priority issue. With color/attribute of 0x80 in videoram at 0xd0000 and 0xd8000, videoram at 0xd80000 will be displayed. Some tilemap guru has to look into this.

Subject: Small SNES changes
Hi,
enclosed please find a patch which changes a bit the way SNES
carts (NSS & bootlegs) are loaded at init time. Currently, data
are loaded once at start and then the read handlers perform various
mirroring tricks. With the attached patch, the cart is loaded at
init and mirrored as many times as it is necessary, while handlers
simply read from the plain offset. Also, blocks of data are mirrored
until they fill all the available banks. Implementing this behavior
both simplifies the handlers code and is more faithful to the hardware
(see mirroring note included in the DRIVER_INIT).
I also slightly changed some handlers to take into account the new
mirroring system. OTOH sram_handlers haven't been updated (they will
be eventually) because with carts as small as the ones in nss.c and
snesb.c, they basically have no overlapping with the new mirroring
approach... as soon as I come up with a satisfactory implementation
that works in MESS (which has to deal with much larger carts), I will
also submit the MAME side.
No regressions appear with the patch, as far as I could test.

Subject: further snes changes
Hi,
enclosed please find a patch which rewrites memory handlers in
machine/snes.c to take into account the additional cart/memory layouts
(mode 22 & 25) which were available for the home console (almost no
impact on nss.c & snesb.c, which only use mode 20 & 21). rather than
only add a bunch of if(snes_cart.mode == XXXX), I preferred to slightly
rewrite the handlers. main changes on the MAME side are:
* merged regions 0x700000 up to 0x7dffff in snes_map (this allows to
make memory maps in nss.c and snesb.c identical: the zone previously
NOPed in nss.c is now handled by snes_r_bank5, because it was not
reserved for all cart types)
* split region 0x800000-0xbfffff from 0xc00000-0xffffff in snes_map.
This simplifies a bit handlers used by MAME and it will be necessary
when MESS supports special chips like SDD-1 (which dynamically changes
the part of cart loaded in the latter region)
* slightly enlarged SRAM regions (in this case, it only affects what
happens inside the handler, NOT snes_map) to support carts with 512kbits
of SRAM (e.g. Thoroughbred Breeder III for MESS). I'm still not 100%
satisfied with SRAM mirroring, but this is closer to the real thing
than the previous way to handle it
No regressions are present, neither in MAME nor in MESS, as far as I
could test (well, for MAME weren't expected, since most changes affected
mode 22 & 25).

Fabio

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
- normalized function and variable names to be lower_under
- removed a number of redundant interfaces from the galaxian/
scamble line of games

Changed render_texture_set_bitmap() to accept a palette object
instead of a palette index. The renderer remains optimized for the
system palette but will work if objects have their own palette as
well.
Changed renderer to permit palettes for RGB and YUY textures. If
specified, these palettes specify a 32-entry (RGB15) or 256-entry
(others) lookup for applying additional brightness/contrast/gamma

palette.c to preserve the alpha when transforming palette values.
These changes should be transparent to almost all drivers and rendering
(ha-ha), but there may be an occasional instance where a driver relied
on the alpha being 0 in the system palette. This also means that the
palette_set_color() function preserves any alpha value that is set.
Changed Firefox to RGB32 to allow for mid-screen palette changes. Because
of the above change, the hacky alpha manipulation that was previously
required is no longer necessary; the alpha is set directly in the palette
entry.

---------------------------------------------------------
I was wondering why functions like 'astring_cmpc' and 'memory_region' where
in the top 5 of the most time consuming functions.
The answer is found in the function 'draw_sprites' from
'mame/video/neogeo.c' where 'memory_region' is called for each sprites for
each VIDEO_UPDATE.
I patched mame in order to keep track of this 'memory_region'. This is done
in VIDEO_START via a global variable (region_zoomy) just like in some other
drivers.

Subject: Speed up fillbitmap
Hi,
there are many places in mame which make use of "fill_bitmap" or the
equivalent "fillbitmap"
An optimisation is done when the depth of the bitmap is 16 or 32 bpp and
when the UINT16 or UINT32 corresponding to the color is composed of same
bytes (i.e 0xffff for example). This is usefull because most of the calls
are for color 0 (black).
In all other cases, the bitmap is filled one pixel at a time using a loop
with a code like :
================
for (y = fill.min_y; y <= fill.max_y; y++)
{
UINT16 *destrow = BITMAP_ADDR16(dest, y, 0);
for (x = fill.min_x; x <= fill.max_x; x++)
destrow[x] = (UINT16)color;
}
================
However, each rows of the final bitmap will be the same. So I modified this
simple assigned to work as follow :
1) fill the first row one pixel at a time
2) fill all the other rows by copying the first one.
This makes us use memcpy instead of a hard coded loop for most of the
filling process.

able to understand how to do this and reworked the DIPs to what is output in the

Modified the laserdisc core to leverage the pre-decoded frame

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

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

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.
- Some corrections to the memory map.
- Added proper working RAM.
- Added Dallas DS1220Y NVRAM.
- Added output port.
- Added lamps layout.
- Added complete inputs.
- Changed description to "Scacco Matto / Space Win" since the default game is Scacco Matto.
You must enter the service mode and change graphics in order to switch the game.

Scacco Matto / Space Win [David Haywood, Roberto Fresca]
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).
* Because twinadv (snowbros.c) had a crash introduced in 127u1, I wasn't able to test the results of the automated IO_MAP merge operation. It's a simple map though, so I don't expect any difficulties. I apologize for not having the time to fix the bug myself (mantis : 02184).
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.
- Better structure and organization.
- Added Super Gran Safari.
- Added improved lamps layout to Super Gran Safari and Magic's 10.

Super Gran Safari [Roberto Fresca]
removed snkwave since it doesn't seem to be used and might not be present on the pcb at all
general driver cleanup, bringing it in line with snk.c but not merging it since somthing doesn't quite fit

The Great Ragtime Show (Japan v1.3, 92.11.26) [Stefan Lindberg]
Renamed the roms for the Japanese v1.5 from kh_0x-1 to kh_0x-2 like the other v1.5 sets. This new earlier version is the "true" kh_0x-1
Slight update to info... the PAL "VF-00" wasn't mentioned. PCB picture is at http://arcade.ym2149.com/
This rom set is not working. Bad dump??? Slightly different encryption??? Emulation issue???
Subject: Update to MC146818 RTC
Hi,
Here's a small patch to the MC146818 code, which gives a basic
implementation of the "update ended" interrupt flag.
The code is based on the behaviour of the Aleste 520EX (Russian Amstrad
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.
(Disassembly attached)
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.
- Added irqs ack
- Implemented raster irq
- Fixed coin2 and service input not working during the game
- Added watchdog
- Fixed visible area
- Added video enable and irqs enable flags
renamed ikaria to ikarinc (for Ikari No Continues)
ikari is the JAMMA board, with conitnues
ikaria is the non-JAMMA board, with continues
ikarinc is the non-JAMMA board, without continues
New clones added

Ikari Warriors (US) [Nicola Salmoria]
Since I touch up a couple of things and test each driver after the automated merge, it still takes a few minutes for each file. More IO_MAP merges will trickle in over the next few days.
It's likely not worth writing every driver in the whatsnew.txt, since there will be ~100.
