Source Changes
--------------
Added deprecat.h that contains some deprecated/discouraged contructs.
The idea is to create extra work if a driver wants to use these and
hopefully gives an incentive to look for an alternate solution. Added
#include of deprecat.h that rely on these contructs. Removed a bunch
of unneccassary #include's from these files. [Zsolt Vasvari]

Simplified Star Fire driver. [Zsolt Vasvari]

drawgfx changes: [Zsolt Vasvari]
- Removed copybitmap_remap and copyscrollbitmap_remap, neither which
was used by anybody
- Removed some obsolete commented out code
- Fixed up some comments
- Removed TRANSPARENCY_NONE case from copybitmap_core, which can
never happen
- Removed TRANSPARENCY_BLEND completely and TRANSPARENCY_BLEND_RAW
as an option to copybitmap. Source tree needs to be recompiled
as the transparancy mode enum has changed.
- Removed TRANSPARENCY_NONE_RAW, TRANSPARENCY_PENS_RAW and
TRANSPARENCY_PEN_TABLE_RAW as they were no longer used.
- Changed copybitmap and copyscrollbitmap. There are now 2 versions
of each, one without and with transparency.

Fixed crash in masao. [couriersud]

Corrected previous i0851 timer fix to use more accurate IE SFRs.
[Jim Stolis]

jedi.c updates: [Zsolt Vasvari]
- Changed video code to directly manipulate the game bitmap
- Background smoothing now happens at the same time as the background
is drawn

Fixed the CPS driver to at least display the correct clock in the
driver info, by degrading the clock through alternate means.
[David Haywood]

m62.c changes: [couriersud]
* fixed wrong resistor value (22K to 2.2K) - verified on spelunkr
and kidniki hires pcb pictures
* Changed resistor network calculation based on assumption that cs
line is active either on tiles or sprites color prom.

Simplified the video code for crgolf. [Zsolt Vasvari]

Added PCB layouts for Penguin Bros & Puzzle De Bowling based on
Hi-res pics. Corrected the seta2.c 68301 base clock as 50MHz / 3
(16.66666MHz) as all the Seta2 hardware has a 50MHz OSC. Secondary OSC
are for other chips (28MHz and or 32.53047MHz). [Brian Troha]

Simplified video code and adjusted some set names in the leland
driver. [Zsolt Vasvari]

Replaced tables with equations in the Sega C2 driver.
[Nicola Salmoria]

Added checks for CROSS_BUILD=1 to omit building m68kmake.exe,
verinfo.exe, png2bdc.exe and file2str. Enables building mame using
mingw on linux. [couriersud]

Various Irem driver updates: [Aaron Giles]
* Properly tagged m52 and m62 sound boards, plus variants.
* Updated all connected drivers.
* Merged memory maps.
* Proper video timing in 10 yard fight.

* Moved definitions to header files.
* Updated mpatrol, yard to use resnet for colors.
* Renamed mpatrol -> m52
* Renamed troangel -> m57
* Renamed yard -> m58

Cleaned up 20pacgal driver, including driver state. Tried improving
on the ROM mirroring, without any success. [Zsolt Vasvari]

Removed colortables from a number of drivers, as part of a larger
move to phase out old-style colortables: gotya, gyruss, ampoker,
circusc, clshroad, champbas, 1943, lucky8, olibochu, yamato,
appoooh, bking, bladestl, blueprnt, carpolo, centiped, cop01,
cosmic, ddrible, irobot, ace, alpha68k, arabian, bfm_sc2, carjmbre,
cclimber, cherrym2, combatsc, contra, fastlane, hcastle, labyrunr,
cham24, multigam. [Zsolt Vasvari]

Removed non-existent, second M6295 from Hit the Ice. Fixes missing
sounds (e.g. team select screen). Hit the Ice/Violence Fight now
share the same sound CPU memory maps. [Philip Bennett]

Improved DIP switches according to manuals for the following drivers:
wboy, chplft, extdwnhl, zingzip, zaxxon, congo, vanguard, zarzon,
nibbler, segag80r.c, yard, kaneko16.c. [RansAckeR]

Verified the sound roms for Rock'n 3 and added proper names. Added
PCB layout for sound rom board only. [Brian Troha]

Cleaned up Time Pilot sound board implementation: [Aaron Giles]
* full memory maps
* partial machine driver removes need for replicating filtering logic
* updated all relevant drivers

Cleaned up Time Pilot and Tutankham drivers: [Aaron Giles]
* correct clocks where possible
* merged memory maps
* fully decoded memory maps
* replaced hacky sprite rendering in Time Pilot with partial updates
* save state support
* removed Power Surge kludge, replaced with unmapped handler control
* Tutankham runs at 60fps, with IRQs every other frame
* Proper IRQ ack in Tutankham
* Proper NMI generation in Time Pilot

Cleaned up pooyan driver. Save states, full memory maps, proper NMI
generation, etc. Flipped video to align better with Time Pilot.
[Aaron Giles]

Changed 6840 interrupt handling to work like the recent 6821 changes.
Updated MPU4 driver accordingly. Updated Scorpion 2 driver to match
MPU4 coding style. [James Wallace]

Resolved all unknown dips in the galpani2 driver according to kaneko's
docs, unified memory maps of both CPUs and repositioned a pair of
graphic ROMS. [Luis Faria]

Made some minor improvements to 1942.c & 1943.c DIPs. Improved
segas16a.c, segas16b.c & system16.c DIPs and added DIP locations
from manuals. [RansAckeR]

Removed distinction between *_gettotalcycles() and
*_gettotalcycles64(). All functions now return 64-bit results. Updated
all call sites appropriately. [Aaron Giles]

Further improvements to SCSP FM. [kingshriek]

Moved cpu_getiloops() and cpu_scalebyfcount() to deprecat.h. Added
#include "deprecat.h" where necessary to make this happen. Cleaned up
cpuexec.c/.h to latest core style. Cleaned up implementation of
extended INP header in inptport.c. Removed external access to
cycles_currently_ran(). Replaced use of cycles_currently_ran() in
v9938 code with mame_rand(), since that is effectively the same thing.
[Aaron Giles]

Added dip locations to about half the games in seta.c. [Brian Troha]

Removed champbas color PROM. Now uses TRANSPARENCY_PENS instead of
TRANSPARENCY_COLOR. Hooked up palette bank selector from schematics,
though I am not sure if it is actually used by the code. Changed set
names to match title screen, which is why baseball is spelt as
"Base Ball". [Zsolt Vasvari]

Some minor cleanup to the equites driver, including memory map
merging. [Aaron Giles]

Added new option VIDEO_UPDATE_SCANLINE, which cases VIDEO_UPDATE to
be called for every visible scanline. Removed manual implementation
of this in timeplt, in favor of using the new flag. There are
probably many more drivers that can leverage this. [Aaron Giles]

Added stream_get_sample_rate(), stream_get_time(), and
stream_get_sample_period(). These functions are not really tested yet
-- make sure they give reasonable results when first used! Updated
streams.h header to latest core style. [Aaron Giles]

Fixed reset crashes in all Z180 games. Removed the various busy loop
and non-exact optimzations from the Z180 core. [Zsolt Vasvari]

Correct colors in Birdie King 3 -- just needed a new dump. Fixed
incorrect ROM names. Switched color decoding to use the resnet code.
[Zsolt Vasvari]

Cleaned up the rockola.c driver. Fixed dip switches for all games.
Added notes about the games. [stephh]

Reorganized exidy440 audio code to make it easier to eventually use
the MC3417/18 emulation directly. Added MC3418 variant support to the
HC55516 audio code. [Zsolt Vasvari]

Updated williams driver to use VIDEO_UPDATE_SCANLINE (most bitmap-
based drivers should.) Converted to 32bpp to catch mid-screen palette
tweaks. Removed some unnecessary read/write handlers. [Aaron Giles]

Improved colors in circusc, gyruss, gotya with the resnet code.
[Zsolt Vasvari]

Significant improvements to Lock-On. Added POLL input handling to the
NEC V20/V30 core. [Philip Bennett]

Changed debugger-related code to be based off a new makefile define
(DEBUGGER) which sets a new compile-time define (ENABLE_DEBUGGER).
This means that MAME_DEBUG no longer means "enable debugger", it
simply enables debugging features such as assertions and debug code
in drivers. Also removed the various levels of opbase protection in
memory.h and always just turned on full bounds checking. [Aaron Giles]

Added some instructions to the H8/30xx CPU: [Luca Elia]
or.l ERs, ERd
rotl/shal.l ERd
not.l/neg.l ERd
exts.w Rd
sub/or/xor.l #Imm:32, ERd
bset/bnot/bclr.b Rn, @ERd
bst/bist.b #Imm:3, @ERd
bnot.b #Imm:3, @ERd

Added H8/3007 & H8/3044 variants with their memory maps. Preliminary
implementation of the H8/3007 timers. [Luca Elia]

Added AM_WRITEONLY as a shortcut for AM_WRITE(MWAx_RAM). [Aaron Giles]

Cleaned up Kangaroo driver: [Aaron Giles]
* documented MB8841 (needs to be decapped to get code)
* proper video timing
* full memory maps
* simplified and more accurate video logic

More opcode improvements to Risky Challenge. [robiza]

Added DIP locations to bking.c [RansAckeR]

Source Changes
--------------
Added internal divider on m680* series CPUs (except the original
m6800). Updated clocks on all games using them to remove the explicit
divider. [Aaron Giles]

Reverted experimental D3D fix, since it breaks switchres.
[Aaron Giles]

dkong updates: [couriersud]
* fix dkong sound following Clock Divider update
* updated to use XTAL_*
* revert a change after sound regression in dkong.

i8085.c updates: [couriersud]
* 8085 has an internal clock divider by 2. Changed i8085.c to reflect
this for I8085. I8080 still at 1.
* Changed driver clocks to reflect internal clock divider
* Added some FIXME: comments where clocks for I8085 are outside specs

Space Fighter Mark II: [Zsolt Vasvari]
- Changed year to 1979 as per Guru's contact
- Renamed set 2 ROMs to allow merging
- Removed experimental code left in there

phoenix.c updates: [couriersud]

* no more colortable

survival updates: [couriersud]
* palette from schematics (resnet.h)

Removed bogus (bad) dump of Heated Barrel US set 2. [Brian Troha]

RSP Changes: [SGINut, Nicola Salmoria, Ville Linde]
- Initialize RSP registers to 0 in lieu of mame_rand
- Re-fix RSP single-stepping mode when set by another CPU
- Reading the RSP PC returns only the least significant 12 bits
- Fixed flag behavior when read out via CFC2
- Fixed RSP VRCP instruction to match the real hardware results
- Corrected VRCP element lookup
- Corrected unaligned DMA behavior

Removed all palette_X_r functions in favor of direct RAM reads.
[Zsolt Vasvari]

Removed no longer applicable assert from VIDEO_START(generic). Removed
VIDEO_START(generic) from drivers that didn't need it. Removed
MDRV_VIDEO_START(generic_bitmapped) from drivers that don't need it.
[Zsolt Vasvari]

Made detection of dynamic attempts to install ROM/RAM handlers more
aggressive. Previous checks would not catch modifications in
DRIVER_INIT or MACHINE_START calls. Fixed a number of cases of
incorrect usage throughout the drivers. [Aaron Giles]

Changed one of the cheat calls back to using more generic switch
detection so they can be triggered via joysticks. [Aaron Giles]

Renamed sauro.c sp0256 internal rom to "sp0256-al2.bin".
Removed BAD_DUMP flag from it as well. [couriersud]

Marked HD6309 as divide-by-4 internally. Updated drivers accordingly.
[Aaron Giles]

* input ports were tagged
* all reads use input port tags
* added dip switch locations from Romstar manual

Added all known variants of the tms5110 as proper chips. Updated
dkong, cvs and scramble to use new chips. [couriersud]

Converted atarifb.c to tilemaps. [Zsolt Vasvari]

- merged memory maps
- complete memory map
- correct video timing
- correct CPU clocks
- replaced protection hack with actual implementation
- cleaned up inputs

Added tilemap_get_scrollx / tilemap_get_scrolly. [Nicola Salmoria]

Preserve fractional part of sample offset when looping in SCSP. Fixes
remaining pitch stability problems. Fixed minor issue with timers
B&C expiring. [kingshriek, R. Belmont]

auto_malloc() once again actually fails when out of memory.
[Aaron Giles]

Switched zn.c to use MDRV_IMPORT_FROM. [smf]

mario.c changes: [couriersud]
* removed all traces to video/generic.h
* fix flipscreen issue with autosave
* on a hires pcb picture, verified resistor and capacitor values

Added dip locations to Real Break. Filled in a couple of dips for the
Pachinko Gindama Shoubu games. [Brian Troha]

Fixed invalid memory_install_*_handler calls in drivers/williams.c.
Emulated external OR circuit for all drivers using the PIA chip. This
used to be internal to the PIA emulation, but, in fact, this is
external logic. The PIA has two seperate INTA and INTB out lines.
This fixes at least PlayBall. [Zsolt Vasvari]

Added the ability to the HC55516 emulator to take an external
osciallator. Updated Mouse Trap to use the new interface.
[Zsolt Vasvari]

Cleaned up and merged ninjakd2, mnight and omegaf drivers into a
single driver. Additionally: [Nicola Salmoria]
- added flip screen support to all games
- fixed sprite overdraw mode:
- ninjakd2 congratulations screen (e.g. stage 3) shows japanese
characters which were previously missing
- in ninjakd2, at the beginning of a level items are visible
during the initial fade in. I'm not sure if this is correct
but the other effects wouldn't work otherwise
- in mnight attract mode, when the big ship is firing the other
sprites no longer leave trails
- in mnight at the end of a level the screen is slowly filled
with balls and then slowly cleared to begin the following
level. Same effect in the death sequence during attract mode.
- added proper computation of sprites to be drawn taking into
account double size sprites. This fixes sticking shots in mnight
without need for a hack.
- lowered ninjakd2 PCM playback rate to 13020 (from 16000). This
seems to sound better and is a round division from one of the
master clocks.
- removed ROM patch that was used to avoid the input protection in
omegaf, added a rough but effective protection simulation.
- corrected some dip switches
- hooked up sound cpu reset line
- simplified ROM loading for the older games swizzling address lines
in driver init.

Added MDRV_SOUND_ROUTE_EX to specify target input channel. Added
input id to route struct. Fixed DISCRETE_INPUT_STREAM and added input
channel # to DISCRETE_INPUT_STREAM. [couriersud]

Fixed default debugger memory view width for CPUs with >byte-sized
minimum. Made menu updating dynamic at click time, fixing issues with
incorrect checkmarks. [Aaron Giles]

Fixed Ninja Kuna. Cleaned up memory maps. Renamed files to ninjakun.c.
[Zsolt Vasvari]

Added MC3417 and MC3418 variants to the HC55516 sound emulation.
Changed Mouse Trap to use MC3417. [Zsolt Vasvari]

Fixed saving i8085 callbacks across a reset. Added 'pull' callback for
the SID pin. This is needed by the Red Alert voice board.
[Zsolt Vasvari]

Made the text displayed by the various UI sliders more intelligent.
Basically, it will only print an index for an item if there are
multiple of a given type. [Zsolt Vasvari]

Updated jailbrek clocks and video timing based on measurements.
[Aaron Giles]

Fixed i8051 timers from firing when not enabled. Checking TCON alone
is not enough to invoke timers. Added IE SFR flags in conditional.
[Jim Stolis]

Added a _CALL variant to all prototype macros. The use of these
should make it easier to change the signiture of these functions in
the future. Replaced existing calls with macro where appropriate.
[Zsolt Vasvari]

Removed VIDEO_START_CALL(generic) from all drivers not needing it,
which were all of them. Removed VIDEO_START_CALL(generic_bitmapped)
from jpmimpct. [Zsolt Vasvari]

Changed YM2203 clock in stfight to 3MHz (compared against OST)
[Yasuhiro Ogawa]

Improved linear zoom effect resolution to address gaps in CPS3
rendering. [OopsWare]

Rewrote and modernized the redalert driver: [Zsolt Vasvari]
- correct colors -- in places different from the manual's description,
but matches the flyer perfectly
- added speech
- fixed AY-8910 sounds
- odds and ends
- corrected colors in Demoneye-X
- added some sound to Demoneye-X
- marked Demoneye-X it NOT_WORKING, due to the (still) missing 3rd
gfx layer that makes it impossible to pass the 2nd level.

Added all the known Naomi BIOS dumps along with descriptions and
information about region bytes & version numbers. [Brian Troha]

Removed the freely distributable Exidy games' dependency on Berzerk.
[Zsolt Vasvari]

Added support for the BLX opcode in ARM7 THUMB mode. [SGINut]

Verified DIP locations from manuals for scramble and 800fath.
[RansAckeR]

Changed S14001A emulator to allow setting the clock frequency instead
of the clock multiplier. This is how the real chip works. Changed the
Berzerk driver to set the S14001A clock as per the schematics.
[Zsolt Vasvari]

Removed the use of the global Machine from a number of places in the
code. [Zsolt Vasvari]

Fixed issues flagged by MSVC warning C4305 (type truncation). Almost
all of these are harmless double->float narrowing in initializers, but
one warning spotlighted a bug in segasyse.c, where code to use a
higher sprite number had no effect due to the insufficient range of
UINT8. [Atari Ace]

Removed /wd4550 for VS7/VS71 compilers (expression evaluates to a
function which is missing an argument list). Fixed some VS7-specific
issues (OPTIMIZE=0 at least compiles now). [Atari Ace]

Added a missing case statement in sm8500d.c, noticed while reviewing
dead code warnings. [Atari Ace]

Corrected Diet gogo h6280 clock so that it behaves correctly with
Charles Macdonald fix to the cpu core. Verified and corrected
frequencies and pin 7 okim6295 on the following games:
The new zealand story (3 z80 version), Trio The punch, Vandyke,
paradise.c games, Downtown, Shaolin's Road and Twins.
[Corrado Tomaselli]

Removed all peplus memory hacks and game specific DRIVER_INIT. There
are now just two DRIVER_INIT, one for normal boards and one for
superboards. Temporarily disabled AutoHold Cheat but documented
addresses for future update. [Jim Stolis]

Added further unencrypted opcodes to risky challenge. The game now
boots with the intro animation. [robiza]

- hooked up crt6845
- converted to tilemaps
- simplified protection(?) emulation
- removed tilemap, a bit more low level video hw emulation
- fake colors

Lowerd FPS in lasso.c to avoid corrupting Chameleon's high score
table. [Zsolt Vasvari]

Removed obsolete uitext.c and all references to it. [Aaron Giles]

Some more modernization/clean-up in the exidy driver. [Zsolt Vasvari]

Added VIDEO_ALWAYS_UPDATED for reliable collision detection in the
CVS driver. [Zsolt Vasvari]

Cleaned up astinvad driver: [Aaron Giles]
* Proper video timing
* Hooked up 8255 PPIs
* Correct interrupt timing
* Consolidated code into single file

i8039.c/mario.c updates: [couriersud]

* fixed XTALs based on documentation

Consolidated exidy and victory drivers. Removed complicated dirty
tracking from victory.c. Reorganized the exidy audio hardware code.
Changed Targ to use a loaded PROM instead of a hard-coded one. Renamed
Side Trak to Side Track as per the title screen. [Zsolt Vasvari]

6821 PIA changes: [Zsolt Vasvari]
- Added orthogonal accessors
- Removed hacky update_shared_irq_handler(), now the same
IRQ callback maybe called multiple times, but this shouldn't
be a problem
- IRQ lines are cleared on a reset

Disabled code in the TMS5220 that set the Buffer Empty flag after a
stop frame. This fixes Victory. This might be the incorrect fix but
the old code wasn't working either. [Zsolt Vasvari]

Hooked up revx dcs reset line. Signaled IRQ on correct CPU when DCS
sends data back (duh). [Aaron Giles]

Removed unnecessary check that could cause SCSP hangs in grdforce.
[kingshriek]

Tweaked deco156 clock speed to be 28 to prevent the games from running
in slow motion. I suspect the 156 chip has an internal multiplier, the
usual input pin is 7Mhz IIRC. [David Haywood]

dkong.c changes: [couriersud]
* added equivalence circuit for Sanyo EZV audio amplifier
* Set DK_C159 = 0 to avoid over-aggressive high-pass filter. Solely
based on observations.
* added comment on above to source
* Added define DK_NO_FILTERS to turn of DAC filters and post-mixer
filters for debugging

Adds dips for Water Balls. Adds dip port locations to all dips.
[Brian Troha]

Added CPUINFO_INT_CLOCK_MULTIPLIER to support CPU clock multipliers.
Updated all CPU cores to return a CPUINFO_INT_CLOCK_MULTIPLIER of 1.
Changed the core to actually respect both CPUINFO_INT_CLOCK_MULTIPLIER
and CPUINFO_INT_CLOCK_DIVIDER. Updated a number of drivers to use
cpunum_get_clock() instead of Machine->drv->cpu[x].clock. Raw input
clock speeds should now be specified for all CPUs in the
MACHINE_DRIVER. [Aaron Giles]

Changed TLC43076 and games using it to RGB32. Removed global Machine
variable where possible. [Zsolt Vasvari]

Removed dirtybuffer from video/generic.c and all drivers still using
it. Good riddance... Removed videoram_w, colorram_w and spriteram_w
and changed all drivers using it to access RAM directly. Removed
videoram_r, colorram_r, spriteram_r, spriteram16_r and spriteram16_w
from video/generic.c and changed all games to use (possibly shared)
RAM. [Zsolt Vasvari]

Cleaned up memory maps in the seibu sound interfaces. Changed to use
shared sound configs instead of statically copying them in each
driver. [Aaron Giles]

Verified and changed cpu frequencies and oki m6295 pin 7 on the
following pcbs: Asuka&Asuka, Cadash, Equites h/w games and sound
board, F1GP, Super Formula, Gladiator, Ping Pong king, Great
Swordsman, Irem m52 sound board, Tropical Angel, Explosive Breakers,
Magical Crystal, Mad Gear, Roller Aces, Chinese Hero, Simpsons,
Golfing Greats, Time Pilot 84. [Corrado Tomaselli]

Added some more static qualifiers on recent new/changed code.
[Atari Ace]

Fixed dbreed72 crash introduced in 0.122u5. [Mamesick]

Fixed HuC6280 low-speed mode so it uses 4 cycles instead of 3.
[Charles MacDonald]

Hand fixed Road Runner's corrupted ROM. We are 99.99% sure that the

[Barry Rodewald]

Added initial FPU support to the SH4 core. [Samuele Zannoli]

Adjusted most conditional logging in MAME to use the idiom
"do { if (VERBOSE) logerror x; } while (0)". This has the benefit that
the compiler checks the syntax of the logging even in the case it will
be eliminated, and in fact a number of cases here needed adjustments
to compile because of this. [Atari Ace]
