* Added logic to simplify opcodes as much as possible at the UML layer.
* Removed similar logic in the x86 and x64 back-ends.
* Added stricter parameter validation for registers and mapvars
* Removed explicit flag requests from the shorthand opcodes
* Added optimization function to drcuml which is called at block end
* Added logic to compute the necessary flags based on upcoming opcodes
and only select those flags which are required
* Updated the PPC and MIPS3 DRCs to no longer explicitly specify flags
* Wrote new disassembler based on enhanced opcode info structure.
* Moved disassembler into drcuml.c and removed old code.
* Extended disassembler buffer sizes to at least 256 bytes.
* Added more extensive per-opcode information in preparation for UML
optimization step.
* Made validation more thorough using the extended information.
* Disabled back-end validation for now until it can be revisited
using the new tables.
* Changed GETFLGS encoding so that the mask is in parameter 2 instead
of the flags field.

- 01845: [Core] all games: cheats are broken
- 01846: [Misc.] -CHEAT trigger causes MAME crash with PSX-type CPU drivers
Source Changes
--------------
Updated cheat system
- Locked search region when malloc fails to allocate gigantic memory
instead of fatal error. Also locked zero malloc error in case of
search speed = all memory in 32-bit CPU. And added search region
range checker to lock a search region with a big risk
- Fixed a bug that old code is always converted to specified
separator in enable/disable menu
- Refined new cheat format.
* Rewritten cheat format again. newest format is
":gamename::type::address::data::extend_data:(description:comment)"
Expanded type field now requires 10 bytes (not 8 bytes) and
it divides internal cpu (2 bytes) and type (8 bytes) parameters
* Removed VWrite, VRWrite. The flag of Value Selection is merged
into expanded type field now.
* 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]

- Renamed many functions/structures/constants
But not complete due to too many items
- Converted small but often used functions to INLINE
- Fixed a comparison in case of 0 or NULL
- Added missing function prototype for several functions

Added new astring functions astring_del, astring_replace, and astring_replacec
to help perform simple search/replace substitution.
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:
- added new 'intention' parameter to the translate callback to
indicate read/write/fetch access, user/supervisor mode, and
a flag for debugging
- updated all call sites to pass an appropriate value
- updated all CPU cores to the new prototype
3. In the UML:

4. In the DRC frontend:
- fixed bug in handling edge case with the PC near the 0 or ~0
Changed error reporting during input port detokenization to fill a buffer
rather than fatalerror-ing immediately. Should now properly skip over
any invalid tokens.
Enhanced error detection during input port detokenization to catch
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.
~aa
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.

* Added discrete sound for filtering ("konami"-style) and mixing.
Hello Aaron,
I have found few more things not ok in T11, this time I have fixed it myself.
1. HALT - should call interrupt vector
2. ILLEGAL - had PC=0 at the end which makes code not run fine
3. MARK - now it is implemented
Can you please check if your drivers are working fine with these cahanges.
After adjustments I have some things working finaly.
Please inform me,

Subject: [patch] Fix 00149: No error report for invalid BIOS setting.
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
code in playch10.c to determine its bios more directly (in other
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

represent the bits you want.
Updated the various MIPS cores that use these functions to invert

Updated all drivers and CPU/sound cores to use the new macros

the machine parameter through a few initialization stacks.
Removed unnecessary postload callbacks which only marked all tiles

Created a complete set of functions for all databus sizes (8,16,32,64) and

which functions to use in which scenarios. It is also now possible to rely
on being able to access values of 8, 16, 32 or 64 bits via the built-in
accessors without fear of crashing.
Updated all cores using 8-bit handlers to explicitly call the 8-bit handlers

Fixed a few games which were calling n-bit handlers directly to use the
generic forms. In the future, this is all the access drivers will have.

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.
Subject: pit8253 device
I have converted the pit8253 implementation into a device. To make it
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

Modified amiga.c to use this information so that we guarantee a call

- 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: 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
Made address versus byte offsets explicit throughout.
Removed some unused parameters.
Consolidated initialization process.
Removed maximum memory block count.
Centralized bank management.
Added masked handlers and change_pc to the accessors.
Added memory_get_accessors() to return a pointer to the accessors
for a given address space/databus width/endian configuration.
More to come.
MRA*_BANK*/MRA*_BANK* -> SMH_BANK*
MRA*_RAM/MRA*_ROM -> SMH_RAM
MRA*_ROM/MWA*_ROM -> SMH_ROM
MRA*_NOP/MWA*_NOP -> SMH_NOP
MRA*_UNMAP/MWA*_UNMAP -> SMH_UNMAP
This removes the silly need for a bunch of redundant constants
with faux type definitions that didn't buy anything.
Moved some memory system constants into memory.c.
Converted address maps to tokens. Changed the address_map structure
to house global map-wide information and hung a list of entries off
of it corresponding to each address range. Introduced new functions
address_map_alloc() and address_map_free() to build/destroy these
structures. Updated all code as necessary.
Fixed several instances of porttagtohandler*() in the address maps.
Drivers should use AM_READ_PORT() macros instead.
ADDRESS_MAP_EXTERN() now is required to specify the number of
databits, just like ADDRESS_MAP_START.
Removed ADDRESS_MAP_FLAGS() grossness. There are now three new macros
which replace its former usage. ADDRESS_MAP_GLOBAL_MASK(mask)
specifies a global address-space-wide mask on all addresses. Useful
for cases where one or more address lines simply are not used at
all. And ADDRESS_MAP_UNMAP_LOW/HIGH specifies the behavior of
unmapped reads (do they come back as 0 or ~0).
Changed internal memory mapping behavior to keep only a single
address map and store the byte-adjusted values next in the address
map entries rather than maintaining two separate maps. Many other
small internal changes/cleanups.
All callers that used 0 for the screen number now use machine->primary_screen
As a gap meassure, Where necessary, create a parallel set of video_screen_*_scrnum functions that take scrnum
All callers that specified a specific screen number now call the *_scrnum versions
Changed game info screen and overlay UI to display the screen tag instead of screen number
- Private state screen information now hangs off the public one, instead of the other way around
- Combines video_global and video_private into a single structure
The following shook out from this that are applicable to other devices as well:
- running_machine is no longer taken, passed or stored
- mc6845_t is now private
- since passing device_config's is not device type safe, I added a
get_safe_token() to mc6845.c to check the device passed in for the valid type.
I think something like this should be added to the core.
- As a side note, I really don't think that device_config is a good name,
naming it simply device_t or something like that might be better.
than tokens and individual bits to the device callbacks. Updated
all existing devices accordingly.
Removed machine from the parameters of some of the device_get_info
and device_set_info calls because that information is stored
with the device now.
* Change "Machine->" to "machine->" in AM_BASE_MEMBER, AM_SIZE_MEMBER
* Pass Machine in construct_address_map
This is not perfect yet, but there is no need any longer to include deprecat.h in drivers using AM_*_MEMBER.

Hi.
In 0.123u3 the bug "multiscreeninfo0123u2gre" was fixed, however it changed
its behaviour as it now shows the "default" resolution the driver uses
rather than the resolution the screen(s) actually use at the moment.

which specify device read/write handlers in address maps, along
with the type/tag of the device they reference.
Converted MC6845 read/write handlers to READ/WRITE8_DEVICE_HANDLERs.
Updated all MC6845-using drivers to use the new macros and call
the updated functions. Removed the many little helper functions
that used to do this work.
Added validity checks to ensure that the devices referenced
actually exist.
Updated all call-through handlers appropriately. Renamed read8_handler to
read8_machine_func, replicating this pattern throughout.
Defined new set of memory handler functions which are similar but which
pass a const device_config * in place of the running_machine *. These are
called read8_device_func, etc. Added macros READ8_DEVICE_HANDLER() for
specifying functions of this type. Note that some plumbing still needs to
happen in memory.c before this will work.
This check-in should remove the need for the global Machine and in turn
"deprecat.h" for a lot of drivers, but that work has not been done. On
the flip side, some new accesses to the global Machine were added in the
emu/ files. These should be addressed over time, but are smaller in
number than the references in the driver.
Usage is very similar to PORT_CUSTOM. See the Astro Invader driver for an example
- Removed input_port_set_changed_callback and converted all users to PORT_CHANGED
The only difference between the old callback and the ones supplied by PORT_CHANGED is
that values passed by PORT_CHANGED are normalized to start at bit 0, just like
PORT_CUSTOM.
suffixed with _func. Did this throughout the core and
drivers I was familiar with.
Fixed gcc compiler error with recent render.c changes.
gcc does not like explicit (int) casts on float or
double functions. This is fracking annoying and stupid,
but there you have it.
video_screen_get_time_until_update().
Fixed CCPU and QB3 to no longer rely on cpu_scalebyfcount().
Fixed busted timing in the CCPU core. Changed watchdog to
count internally rather than using external watchdog support.
Altered CCPU to accept interrupt signals from the driver.
Updated clocks in the cinemat driver to be derived from the
clock crystal.
* Illustrates how to keep existing memory read/write handlers
This is slower than caching the device interface, but does not have an impact on
devices accessed at a low frequency like in this case.
* added ATTR_FORCE_INLINE to osdcomm.h

- Added a video_screen_register_vbl_cb() function for registering VBLANK callbanks
- Changed inptport.c and debugcpu.c to make use the VBLANK callbacks
- Added video_screen_get_time_until_vblank_start()
- CCPU and anything using cpu_scalebyfcount() are currently broken
- I did some fairly extensive testing, but this is a very signficant internal change,
so some things may have broke
to use the macros.
Added the concept of device classes. Devices specify their class
in their get_info function. Classes can be used to walk through
devices at a more general level than their type. Functions have
been added to iterate through devices by class just as you can
by type.
Removed some unused fields from device_config.
- Since the Commodore 40xx computers program an HSYNC width that extends past the end of
the scanline, I am clamping it in lack of anything better to do.
- Define a new MDRV_CPU_VBLANK_INT_HACK() (ZV: defined in deprecat.h) which is a copy of the current MDRV_CPU_VBLANK_INT()
- Find all the places where VBLANK_INT is used with something other than 1 interrupt per frame and change it to the new macro
- Remove the "# per frame" parameter from the MDRV_SCREEN_VBLANK_INT() and add a screen tag in its place; updated all callers appropriately.
- ZV: Added some validation of the interrupt setup to validate.c
The idea behind this is that using a VBLANK interrupt with more than one interrupt per frame in conceptually wrong.
The screen tag will allow us to move the interrupt timing code from cpuexec.c to video.c, where it really belongs.
Subject: A fix for the z80pio
Hi there,
Here is a one-line fix for the z80pio.
At the moment when the interrupt control word is sent (with interrupts
enabled), an interrupt occurs. In reality, interrupts are disabled until
the interrupt mask byte is sent.
Subject: MPU4 Changes part 2
Right, I've added a bit of CTS pin checking logic, so that the status
flag is actually set when the pin changes state.
I've also simplified the MPU4 ACIA clock logic, but it's still not ideal
(Ideally, the ACIA should only run one transmit or receive event each
time the PTM O1 pin goes high, but that's not possible right now, so I
just set the clocks as close to off as I can when the pin is low, and to
something that approximates the distance between output state changes
when it's on). There's also a few more little cleanups based on
schematics and flyers from TAFA, and an emulation of the master reset
behaviour. Incidentally, if anyone wants to see just why this isn't
kicking into life now, by all means do, since there's nothing left that
I can see that it can get hung up on, other than the video chip, and the
aforementioned ACIA logic.

uPD78C06 cpus to the uPD7810 cpu core.
This fixes the ape sprite positioning in Crazy Kong -- no more gap between feet and platform
- Merged Yamato driver with Crazy Climber
- XX Mission tilemap conversion
- Removes VIDEO_START(generic) -- no longer used
constructors to tokenized lists. For the most part
this is a non-invasive change, except for those drivers
using MDRV_WATCHDOG_TIME_INIT. In order to allow for
tokenization of attotimes, a set of new macros is
provided called UINT64_ATTOTIME_IN_x() which follows the
same pattern as ATTOTIME_IN_x() but packs the attotime
down into a single 64-bit value for easier tokenization.
Separated MDRV_DEVICE_CONFIG_DATA into 32-bit and 64-bit
versions. Added floating-point versions with configurable
resolutions.
Fixed several errors in the machine drivers which were
caught by the additional checks now done in the machine
config detokenization code.
Converted speakers into devices. Machine->config no
longer houses an array of speakers; instead they are
iterated through using the new macros (defined in sound.h)
speaker_output_first() and speaker_output_next(). Updated
all relevant code to do this.
Improved game info display with multiple screens. Fixed
bug which caused all screens to display equally.
Added typedefs for all the machine config callback
functions at the top of driver.h.

- I still left drawgfx.c as is, the only piece of code that used any of the functions in drawgfx
was s2636.c -- everything else uses 8-bit bitmaps as a replacement for a two dimensional array
- Moved some variable declerations so that they are only visible where they are actually used
Note that the diff is large only because I removed a level of indentation from a huge chunk of code.
I could do that because the case it was checking for was already caught by one of the asserts added.

verinfo now uses the following syntax: verinfo.exe -b windows|winui|mess.
Does not depend on compile time defines any longer.

ALL DRIVERS MUST NOW EXPLICITLY DECLARE THEIR SCREENS.
Read on for more detail....
Added device tag as a parameter to the start function for devices.
Updated MC6845 to accept this tag.
Added new functions for iterating through the device list and
counting devices of a given type. Updated search and iteration
functions to accept DEVICE_TYPE_WILDCARD to work across all
devices.
Added new macro MDRV_DEVICE_CONFIG_DATA() which is used to set a
single item in an inline data structure.
Removed the per-screen palette_base. This was an idea that never
really worked out, nor have we really needed it.
Defined a new device type VIDEO_SCREEN. Currently this has no
live functionality, but merely serves as a placeholder/identifier
for video screens. Eventually some of the screen management code
may move into the start/stop/reset functions.
Changed MDRV_SCREEN_* macros to build up VIDEO_SCREEN devices
rather than storing values in the screen[] array.
Changed MDRV_SCREEN_ADD to specify a screen type (RASTER, VECTOR,
LCD for the moment).
Removed the older VIDEO_TYPE_RASTER and VIDEO_TYPE_VECTOR; this
information is now determined by walking the screen list.
Removed the screen[] array from machine_config. Modified all code
referencing Machine->config->screen[] and changed it to iterate
over the devices using the new video_screen_first() and
video_screen_next() functions.
(The next step will be to add video_* functions that accept a tag
instead of screen index, and then move systems over to always
referencing screens by tag instead of index.)
Removed implicit screen #0. This means that ALL DRIVERS MUST
EXPLICITLY DECLARE THEIR SCREENS. Updated all drivers to do
so. While there, grouped all MDRV_SCREEN_* parameters together.
Also removed unnecessary VIDEO_TYPE_RASTER and VIDEO_TYPE_VECTOR.
Also removed VBLANK and bitmap format information from vector
games. This was painful and very tedious.
Changed game information to display info about all screens.
* PALETTE_INIT no longer has a colortable parameter
* removed game_colortable and remapped_colortable from machine_config
* updated a few stragglers that still referenced these fields
* removed tile_draw_colortable from tilemap.c
(From Zsolt): Added support for the new colortable object in the palette viewer
Changed the input port tokens to use a union instead of casting everything to FPTR.
In the future, C99-enabled compilers will be able to achieve type safety with
designated initializers.
Subject: _mul_32x32_hi() and _mulu_32x32_hi() patch
Hi/2.
I've attached patches to fix validation fail of '_mul_32x32_hi()' and
'_mulu_32x32_hi()' inline function when compiled GCC v3.3.5 with I686
optimization in according to advice of 'Vas Crabb'
Subject: Various little changes from the last month
I've been meaning to send these in for ages, but the day job has been
insane for a while now, so it's been hard to keep these up to date.
Firstly, I've fixed a few corner cases I've noticed in the 6840
emulation based on running the MPU4 test ROMs, and added the ability to
dynamically alter the external clock frequencies in game (since these
pins can be connected to other timing devices in a daisy chain, this may
well prove handy for speech chips and the like).
The 6850 core has also been changed to allow dynamic RX and TX clock
alteration, to at least try to remove a few of the MPU4 timing problems
(the ACIA clocks are triggered by the output pin of one of the 6840
timers, so the clock rate will vary according to what has been
programmed into the counter, rather than a fixed value).
MPU4 has been changed to document the Video board a bit better, and to
change a game name to match what is actually on the marquee. Other names
have changed, to better describe the program nature (AMLD versions are
legally speaking not SWPs, as there is no capacity for payout, so AMLD
SWP is an oxymoron).
Lastly, since I was smoketesting 6840ptm using cchasm anyway, I've added
some documentation of the Cosmic Chasm crystals, and merged the memory
maps.
to the sound and CPU interfaces. This is still a bit WIP, but works at
a fundamental level. Currently the only example of usage is in qix.c for
the MC6845 CRTC.
New module: mconfig.c/.h. Moved all machine_config and MDRV_* macros here,
out of driver.c/.h. Added MDRV macros for adding/removing/configuring
devices.
qix.c: Moved video part of machine driver to video/qix.c. Added MC6845
as a device in the machine driver. Removed explicit MC6845 initialization
from VIDEO_START in favor of simply retrieving the token from the device
interface code.
mc6845.c: Updated all callbacks to pass the mc6845_t * object. Updated
all drivers accordingly. Added a minimal device interface.
Deprecated the following constants because global constants that pretend
to document things but which are only guesses are dumb:
- DEFAULT_60HZ_VBLANK_DURATION
- DEFAULT_30HZ_VBLANK_DURATION
- DEFAULT_REAL_60HZ_VBLANK_DURATION
- DEFAULT_REAL_30HZ_VBLANK_DURATION
- DEFAULT_60HZ_3S_VBLANK_WATCHDOG
- DEFAULT_30HZ_3S_VBLANK_WATCHDOG
Updated all drivers to explicitly specify the equivalent bogus times.
Added comments for the "REAL" VBLANK durations to indicate that they are
not accurate.
Hi mamedev,
Here's my periodic batch of code cleanups. The usual batch of adding static/const plus some include fixes. In addition, I reverted some of the changes to build.mak from u1 which made some MSVC builds fail, and adjusted/optimized an m10.c gfx_layout. I also added some missing cores to cpuintrf.c, sndintrf.c and added some missing #if's to 5220intf.c.

Since it's an SCSPx2 with ADPCM instead of FM it's already feature-complete except filter envelopes.
A bug in the ARM7 core causes incorrect pan/level values to be computed in e.g. the Naomi SOUND TEST menu (I've also been seeing this in DSF playback). This is not a defect in the AICA.
Please credit ElSemi, Deunan Knute, kingshriek, and myself.
moved decryption table setup to 'config' struct for the CPU.
added latest tables from robiza, making Risky Challenge playable, promoted it to working
told CPU core to not decrypt code after brkn instruction, enabling it again on iret, allowing me to remove several 'don't decrypt range' hacks in robiza's code.
updated all drivers accordingly.
currently the disassembly is a bit weird now, this will need looking at.
Samuele Zannoli:
- Add SH4 I/O ports
- Connected the 93C46 of the naomi and the x76f100 of the rom board and filled them with dummy data to satisfy the BIOS
- Implemented some of the JVS transfers that will be needed to use the controls
- Implemented ROM board DMA
- Set proper NAOMI RAM sizes (32 MB main, 8 MB for AICA)
- Improved PVR-TA graphics emulation
Deunan Knute:
- Set proper ARM7 clock. (Yes, it's really that slow!)
Subject: [patch] CPU/SOUND independence fixes
Hi mamedev,
Here's some updates to the CPU/SOUND cores to improve build
independence. While I was at it, I rescued the M65CE02 core from
bitrot hell (perhaps m65ce02.[ch] should just be deleted), and fixed
some MESS cores that were broken by the deprecat.h changes.
Subject: Frequencies verifications
I corrected the clocks on the following pcbs: Formation Z, MagMax,
SlapFight and Tiger Heli
Changed Oki m6295 pin 7 to "high" on Toki and Blood Bros
