Subject: small submission
Hi,
enclosed please find a tiny diff which makes megadriv_vdp_r & megadriv_vdp_w
handlers in megadriv.c non-static (and includes them in megadriv.h).
This small change, while making essentially no difference for MAME, would make
life easier to maintain pico emulation in MESS.

Hi,
enclosed please find a patch which fixes the red/blue inversion for eolith.c

Hi there,
Astro Wars (Zaccaria 1980) can be added to the galaxia.c.
The attract mode works and it uses the same hardware and
the rom names/lacations are identical.
The picture shows three screenshots of Astro Wars, the left and middle uses
only one of the gfx roms and the right both.
M*A*S*H
New game NOT WORKING: Astro Wars
* Added roms/unemulated/Irem/iremM10_incomplete.zip as ipminva1 to m10.c
* Marked as GAME_NOT_WORKING
* The roms are all different from ipminvad, one is missing. The game does
enough to see that it is some sort of invaders type game.
* Added roms/unemulated/Irem/ww3_roms.zip as ww3 to redalert.c
* Dumped by Stefan Lindberg
* Please credit Stefan Lindberg as well
* Either redalert is the clone or ww3 is the clone. Redalert has a speech board in addition
to the m37b audio board.

New games added or promoted from NOT_WORKING status
---------------------------------------------------
WW III [Stefan Lindberg, Couriersud]
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
- Simulated the co-processor to pass the initial test.
- All Inputs worked from the scratch.
- Fixed position of tilemap layers.
- Added scroll register preliminary support.
- Fixed Super Pool graphics.

Subject: two more patches
Hi,
enclosed please find the following patches
* portM.diff which completes the basic port cleanup in
drivers starting with M. It's mostly conversion of 8bit
-> 16/32bit inputs and usage of AM_READ_PORT in memory maps
(plus a couple of eeprom_bit_r replaced with PORT_CUSTOM
and daitorid_soundstatus_r in metro.c converted to a
CUSTOM_INPUT as well)
* avgdvg.diff converts most of the games checking avgdvg_done()
in inputs to use a CUSTOM_INPUT (which I added to video/avgdvg.c).
avgdvg_done() is still in use in mhavoc.c (which requires some
more changes, so I'll take a look later) and in omegrace.c (which
reads it directly and not through inputs). While at it, I've
also done a small cleanup of inputs in starwars.c and tempest.c.
Regards,
Fabio
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.
~aa
Subject: few more patches
Hi,
enclosed please find a few patches to continue the input port
clean up (and to fix a mistake in the previous submission). In
detail:
* hal21.diff: with my last submission I made a mistake in hal21.c
(I converted it only partially to custom inputs, still returning
1<<5 instead of 1 from the handler). please revert that change
(it was in u4_custom04.diff) and apply this one, to fix the
communication with sound cpu
* clean_new.diff: introduce AM_READ_PORT & c. in drivers starting
with M (only few of them updated, more to come)
* custom_new.diff: improves input handling in mainsnk.c and marvins.c
by using CUSTOM_INPUTs and AM_READ_PORTs
* gaelco3d.diff: converts radilkalb inputs to 32bit inputs (as
they are), removing the need of AM_READ16 for those
* itech32.diff: converts inputs of later games to 32bit inputs and
updates all the occurrences as needed. It also simplifies input
handling by removing special_port_r from most of the maps (replaced
by a CUSTOM_INPUT). Now only drivedge still uses 16bit inputs and
special_port_r, but I'll investigate it later.
* arkanoid.diff: changes mcu reads to CUSTOM_INPUTS (and muxed
inputs as well). Bootleg inputs has been slightly changed as well
to cope with the new implementation of the protection
* irem.diff: this patch changes a lot of input related things in
m10->m107 irem boards. First of all, it moves input definitions from
drivers/m92.h to include/iremipt.h (which was already there, just
a bit unused ;) ) and it removes completely drivers/m92.h (which
only contained those definitions). Moreover, it adds more common
inputs to iremipt.h and starts to use that file in m62->m107 instead
of local #defines. Finally, it adds diplocations to all the games in
m62->m107 which were missing and it implements coinage mode 2 through
dipconditions in the drivers which didn't support it.
I tested as much as I could these changes and I can see no regressions.

Fabio
Subject: [patch] Fix 1802 cybrcomm, raveracw, raveracj, raveraja,
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.
Subject: some more input clean-ups
Hi,
attached please find a few patches against u4. These diffs improve
input ports for drivers starting with F->L. In particular: they add
AM_READ_PORT whenever suitable, they make inputs fully 32bit where
needed, they remove indexed input read handlers from INITs, they
replace many read handlers with appropriate CUSTOM_INPUTs.
Additional improvements:
* added dip switches and locations to go2000 (even if they were
partially documented in the source)
* fixed artmagic protection (it used a wrong tag, which probably
I added somewhere in 0.125uX); even if I haven't experienced any
problems due to the bug since the regression now it's fixed
More details on the patches:
* u4_clean01 -> u4_clean07: these are standard changes like the
one I submitted previously (no custom inputs involved)
* u4_custom01 -> u4_custom04: here there are also changes involving
custom inputs (they mainly deal with eeprom reads, but a few were a
bit more interesting); I separated these from the other ones in
case you want to check them more in detail
* itech8.diff: this patch improves ports & their handling in itech8.c.
In particular, it replaces the 'special' handlers with a single
custom input and I would like a confirmation that it was the right
choice in this case.
Patches are independent one from the other and should apply with
no problems. Let me know if this is not the case.
Regards,
Fabio
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.
1) convert framebuffer's ram from 8 bit to 16 bit
2) convert dma command from 8 bit to 16 bit
3) convert gfx command from 8 bit to 16 bit
4) implemented all gfx mode: 1,2,4,8,16 bpp
for now the rendering is only 8 bpp
now we can use this gfx chip for adp driver that use 4bpp
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.
Marked madalien and madalina as Imperfect Graphics. They are missing an effect. When you shoot an enemy in the dark, the whole screen lights up. Basically the headlights fill the whole screen.

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.

(This completes adding all of Guru's readmes to the MAME source. There remain ~20 readmes that I still need to compare to what's in MAME to see if they have any additional information, but beyond that, this little project is done!)

Added a new Japanese version of Ghouls'n Ghosts.
This could be a hack since, running on a 91634B board, it must have been made at least three years after the initial release of the game. However, if if it's a hack, it's exceptionally well made since all ROM stickers look original and the B-board DAM63B PAL label is printed on the chip.
Also, hack or not, the code alignment of none of the already supported versions matches this one so it appears to at least be based on a new version.
The dip switches need to be checked. The Lives dips, and the two unused dips after those, also change the starting level. This could be further evidence that the game is a hack.

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

cheat to its default value.

Subject: New russian game
Dear Aaron,
thanks to the very kind and good guys at the "Soviet Arcade Games Museum"
(www.15kop.ru), namely Alex and Max; and thanks to Antro (a good friend of
mine), we have a new dump for a previously unknown Russian game: S.O.S. by Terminal.
It works on the same hardware as Konek (already in MAME), it's a simple rom
swap. I still have to chek about PROMs.
A diff file is included, together with roms.
All the best

Subject: some diplocations
Hi, enclosed please find a patch to add diplocations to the some
drivers which still missed them. The patch assumes my changes to
drivers starting with C,D,E have been applied (port01.diff -
>port09.diff I sent on Aug 1st... there is at least crshrace.c w
hich could fail to correctly patch, due to possibly different tags,
and probably 1 or 2 more... not many, but maybe annoying anyway).
It adds diplocations to the following drivers: combatsc.c, copsnrob.c,
cosmic.c, crgolf.c, crimfght.c, crospang.c (here I also added service
dips to heuksun and bestri, which allowed me to verify locations),
crshrace.c, dambustr.c, darkseal.c, dassault.c, dblewing.c, ddrible.c,
deadang.c
It also adds locations to the following games: ddragon & ddragon2 on
ddragon.c and docastle, dorunrun & dowild in docastle.c

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: another small fix
Hi,
with this last patch I hope to have fixed all regressions I could

PORT_START_TAG to PORT_START.
From: Fabio Priuli [mailto:doge.fabio@gmail.com]
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.

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%

Jingle Bell [Luca Elia]
Like some other Space games (mosaic.c), it is protected by an MCU
that supplies the addresses to jump to.
I've done some basic simulation that at least shows the service mode.
This is a candidate for decapping / trojaning, or for Nicola to examine
like he did with Mosaic ;-)

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.

Subject: a few cleanups
This patch contains:
- removal of unprintable chars (newlines) in SH-2 disassembler (I
submitted this in the past nd it wasn't included)
- 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
necessary, if the debugger.h one would be removed)
- 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
names
files. Removed old option 'cheat_file'.
Updated xmlfile.c to specify the line number for each node, for more
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.
Game is NOT WORKING because it uses an H8/3644 MCU plus an IDE HDD to emulate the home PS1 version's redbook audio tracks. Cross your fingers for decapping.

Hi,
enclosed please find a few more patches based on 126u2. It's just a few
minor bugfixes because I'm quite busy and I still have to test the other
changes to tagged inputs (I will send them in the next few days)
In misc2.zip you'll find a few corrections to my previous patches and a
few new bugfixes:
* cachat.diff: It fixes bug 2046. This is a bug I introduced misreading
the default value of the flip dip when updating taito_l.c to use
taitoipt.h definitions. My bad, sorry.
* witch.diff: It fixes another small 'mistake' I introduced when tagging
the ports in witch.c. I searched and replaced a few too many 'port'
occurrences, making some comments unreadable. Again, sorry for the
inconvenience.
* btime.diff: It's an updated version of my previous patch, following
your suggestions. 'Off' comes always first now and manual settings which
do not work on the emulated game are commented out
* skyfox.diff: It fixes bug 2050. Being at it, I also added dip
locations to the driver and updated memory maps to use AM_READ_PORT
* combatsc.diff: It fixes bug 456, solving both the regression which
made disappear all sprites (they were covered by the non-transparent
text layer since 118u1) and the corruption of the graphics in title
screen (due to the wrong drawing order). Mind that bug 400 (scrolling
problems present since 0.79) is not fixed yet, unfortunately.

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.

Fixed buffer overrun in latest SCSP code. Not sure how that ever

colmns97 still asserts in SCSPDSP, but this happened before the

- Pre-defined CPU and SND clocks.
- Switched the color system to RESNET calculations.
- Completed the remaining DIP switches.
- Added lamps support. Created a layout to show them.
- Changes on the interrupt system (need to be verified on the PCB).
- Renamed the graphics regions to more descriptive names.
- Corrected the manufacturer's name.
- Splitted the driver to driver + video.
- Updated technical notes.
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.

Subject: more tags and AM_READ_PORT
Hi,
with the following patches I added tags to all ports (and used AM_READ_PORT
in the memory maps of all the drivers which didn't) in drivers starting with
B. I also added diplocations and factory settings for the games which had
either a manual or a dips listing at crazykong (and to squaitsa, thanks to
a scan from f205v) [1]. A couple of patches are separated from the main ones
because they contain changes which could need additional review
In details:
* diffB01->diffB07 contains standard addition of tags and AM_READ_PORTS to
driver starting with B (a diff each 4/5 drivers).
* bsktball.diff adds diplocations to the driver, but also removes the fake
handling of P1 Start/P1 Button1. Since other games have no separate P1 Start
in MAME (e.g bagman, or joust2 as noticed in the invalid bug 1734), I
personally see no reason to duplicate inputs in this game.
[1] In details, I added locations to: bwidow.c & bzone.c games, bestleag,
blackt96, bogeyman, bombjack, boogwing, bottom9, brkthru, darwin, buggychl,
squaitsa, btime, bnj, lnc, zoar and disco

Subject: last batch of misc. diffs
Hi,
attached please find a few patches to fix some (trivial) mametesters' bug
and a patch to use whenever possible AM_PORT_READ in drivers starting with
# or A. More in detail
* hypreact.diff 'fixes' bug 1572 on MT (not really a bug, in fact), adding
a better description to inputs only used in Joystick Mode
* alleymas.diff 'fixes' bug 1565 on MT. In this case I'd like some dev to
review the patch: the two duplicate inputs in alleymas are properly detected
also in service mode, so MAME is not wrong as is. Nevertheless, inspired to
the common habit of commenting out duplicate coinage inputs, I decided to
comment them out but leaving them in the source for documentation purpose
* bishi.diff fixes bug 1718 on MT. Duplicate inputs did nothing and the new
inputs are now correct both during the game and in Service Mode
* Finally, portA.diff is a bit more interesting and converts a few driver to
use AM_READ_PORTs and tags. Here and there, I also changed a few tags to e.g. s
tress similarities in the handling which were hidden by anonymous "INn" tags
(see atarifb & atarifb4 for instance)

Subject: a few bugfixes (or at least proposals of fix)
Hi,
enclosed please find the following patches for bugs currently
in MAME (sorry for the verbose explanations, but I hope it makes
faster the verification and not to steal too much time to the
reviewer)
correct fixes (IMHO)
* harddriv.diff : Fixes a bug introduced in u7 which broke racedrvc,
hdrivair and their clones (due to some tags not being renamed).
Strange no one has noticed this (not even Firevawe when he ran its
regtest before 0.126!), anyway now it's fixed...
* gstrik2.diff : This patch fixes bug 1568. One of the two service
mode keys doesn't give access to the service mode (and in fact it's
not read at all in the input test in service mode). I changed it to
an unknown dipswitch
* atarijsa.diff : This changes the ports #defined in
src/mame/audio/atarijsa.h to be EXTERNAL_INPUTS (and modifies
accordingly the drivers using them). It allows to remove the SWAPPED
version (modified locally in xybots.c) and it allowed me to fix half
of bug 818 (duplicated coins in stunrun). Indeed, stunrun and steeltal
use their own coin input and the jsa ones are not recognized in
Service Mode. Therefore, I removed them through PORT_MODIFY. @Aaron: I
left in COIN3, even if those games do not use it, maybe it can be made
UNUSED as well
proposals:
* leland.diff : I noticed that the SERVICE MODE key in leland.c games
doesn't do anything service related, but it simply adds a coin. This
patch changes them to IPT_COIN3 (because this is the mapping of the same
inputs for offroad and pigout). Actually, it could be an IPT_SERVICE1
(but I don't have currently access to any manual to verify it) or there
could be a different bug in the driver causing the input to be read as a
coin... If one of the latter options sounds more correct to you, please
change the IPT or ignore this patch.
[Note: this was changed to IPT_SERVICE1]
* pc10.diff: This one fixes bug 595, i.e. Start button in playch10.c is
currently mapped to key "2". This could be by design, but it's a bit
confusing since it works the other way around in vsnes.c. If it was by
design and you don't plan to change it, please post at MameTesters so
that we can close the report as Not-a-bug.
* twotiger.diff : This addresses bug 1448. The wheel is completely
centered for any value in the (closed) interval [0x64, 0x69] (goes to
left for 0x63 and to right for 0x70). I've chosen 0x67 because it's in
between, but I'm not sure 100% about the way analog inputs are managed
in the core, so feel free to use another value in that range if it m
akes more sense than 0x67.
That's all. Thanks for the atention

Hi mamedev,
The attached patch makes the initialization of various Konami PPC

Subject: a last bunch of patches
Hi,
attached please find a last block of diffs which completely removes
every explicit use of input_port_read_indexed from src/mame/ (it
remains in the various input_port_N_r, but I'll move to those later
:) ) and fixes a small input bug
Namely:
nbmj_fix.diff: fixes bug MT 479. livegal turns out to use in a
slightly different way the nichibutsu mahjong panel and inputs in
test mode confirms that my change is correct ;)
patch01.diff -> patch03.diff: convert to use tagged inputs and
handlers the remaining drivers (U to Z and a few others)
taito.diff: converts taitoic.c handlers to use tags (this required
some more re-tagging in a few taito drivers, which I overlooked previously)
namcos22.diff: converts namcos22 read handlers to use tags. I have
been very carefully about where each read handler is used (and adopted
read_safe where necessary), so there shall be no problem with this
(despite the complexity of the driver)
mediagx.diff: finally, I re-submit this patch about mediagx.c. Much more
work would be needed to correctly map inputs for this driver, but I fear
is still a bit beyond my current skills. However, from inspection through
the debugger and from error.log, you can notice that the variable
parallel_latched (used to read inputs) takes values 0,...,23 so this diff
does no harm to the driver and allows to remove also the last occurrence
of input_port_read_indexed!
As usual, I tested as much as I could the changes and I expect no
regressions is introduced
