20th May 2000 : Jarek Burczynski fixed some YM2151 bugs.

0.36RC1: Only one of the two YM2151 emulators is linked, this is determined at compile time. The default is Jarek's, which is more accurate though a little slower. It can be replaced with Tatsuyuki's changing the makefile. Jarek Burczynski did improvements to the YM2151 emulator.

0.36b12: Tatsuyuki Satoh fixed OPN and OPM output level. Unfortunately this means that all games using YM2203, YM2151 etc. need to be rebalanced.

6th December 1999: Jarek Burczynski rebalanced the YM2151 core.

14th November 1999: Tatsuyuki Satoh fixed LFO in YM-2151.

5th November 1999: Jarek Burczynski fixed a small bug in YM2151.

24th October 1999 : Bryan McPhail added an original Tumblepop romset (with correct YM2151 sounds) to the driver.

0.36b7 : Aaron Giles fixed YM2151 sound board support for Joust 2. Jarek Burczynski improvements to the other YM2151 emulator too.

12th February 1999: Nicola added YM2151 support for Street Fighter 1, but samples are still missing.

0.34b8 : Support for stereo output. This is implelemented in the YM2610 and in Tatsuyuki's YM2151. It can be used by other games, for example the Atari System 2 games (Paper Boy etc.) have two Pokeys, one per channel. [Nicola Salmoria]. [DOS] Stereo sound support. It is a little slower than mono, to turn it off use -nostereo. Stereo is enabled only for YM2610 and YM2151 games. The others always use mono.

0.31 : Tatsuyuki Satoh improved YM2203 and YM2151 emulator, and DAC interface, with 16 bit samples support. Jarek Burczynski program a new YM2151 emulator, used by Rastan and others.

0.30 : YM2151 emulation. [Tatsuyuki Satoh]

Note: Neill Corlett writes a YM2151 doc. The emulator Callus can log the YM2151 register writes to a .CYM file.

S3.3 YM-2203

0.36b12: Tatsuyuki Satoh fixed OPN and OPM output level. Unfortunately this means that all games using YM2203, YM2151 etc. need to be rebalanced.

17th June 1999: Brad Oliver fixed YM2203 core to be multi-session friendly.

0.35b2 : Bryan McPhail fixed the YM2203 in Ghost Busters.

0.35b1: Partial sound in The Real Ghostbusters. The YM2203 doesn't seem to work correctly. [Nicola Salmoria]

0.34b6 : [DOS] Nicola replaced the -fm option with -ym2203opl. Added -noym3812opl to use the digital emulation of the YM3812 instead of the SoundBlaster OPL chip. Note that with -noym3812opl you also need external drum samples.

0.31 : Tatsuyuki Satoh improved YM2203 and YM2151 emulator, and DAC interface, with 16 bit samples support.

0.30 : Tatsuyuki Satoh added YM2203 emulation not using the SoundBlaster OPL3 chip. This is more accurate than the previous one, which used the SoundBlaster OPL chip, however it is also slower. You can still revert to the old behavior using the -fm command line option. Nicola added partial emulated sound in Bubble Bobble (only the YM2203 chip, therefore only some sound effects - no music).

0.23 : "And there was MUSIC!". Thanks to Ishmair's FM engine, music is supported in Commando, Ghosts 'n Goblins, Diamonds. Since the synthesis is based on FM generation via OPL, you must have a SoundBlaster, Adlib, or compatible to get the music.

0.22 : Nicola added COMMANDO. Original Sound is done by YM2203 (FM synthesis) while now is done by 8910 (no FM). So music is not present.

Note: Emulator JFF emulates the YM2203 chip via OPL3 chip (most Sound Blasters and clones are equipped with it. OPL3 can't really emulate the YM2203 chip, but by some fiddling one can get reasonable sound out of it.)

S3.4 YM-2413

16th July 2000: Brad Oliver adapted Charles MacDonald's YM2413 emulation into MAME, though its accuracy is not yet known, so it might or might not replace the current emulation.

0.37b4: Improved YM2413 emulation. [Paul Leaman]

7th June 2000: Paul Leaman sent in a YM2413 update with proper frequency calculations.

19th May 1999 : Paul Leaman did a bit of cleanup on the YM-2413 code.

Games: Pang, Buster Bros, Rampart...

S3.5 YM-2608

0.37b3: Aaron Giles fixed YM2608 adpcm support.

22nd May 2000 : Aaron Giles improved the Exidy sound system, fixed some YM2608 core bugs

0.34b2: Tatsuyuki Satoh updated the FM emulation and the way the 8910 updates its buffers. FM also has support for YM2608 and YM2612, though they are not compiled in.

S3.6 YM-2610/2610B

16th September 2000: David Graves abstracted the Taito YM2610 sound interface.

0.36b15: Source: Added gain support to mixer.c, through the new MIXERG() macro (extension of MIXER()). Removed the gain filed from AY8910, YM2204, YM2610 structures.

0.35b6 : Improvements to the YM2610 timers, added an interface for external volume control. [Tatsuyuki Satoh]

Games: Shadow Dancer (Sega 1989), Alien Storm (Sega 1990), Blocken (Visco 1994)

S3.11 YM-3812/YM-3526

0.36b2 : Tatsuyuki Satoh make further improved the YM3812 emulator, especially the rhythm section (check Snow Bros!). [DOS] -noym3812opl is now the default (this won't have effect unless you delete mame.cfg). [Nicola Salmoria]

30th July 1999: Tatsuyuki Satoh updated his YM-3812 core yet again, fixing crashes.

23rd July 1999: Tatsuyuki Satoh fixed yet another YM-3812 emulator bug and fixed rhythm sound handling in the YM-3812 emulator.

21st July 1999: Tatsuyuki Satoh fixed some YM-3812 IRQ problems, for example with Raiden.

0.36b1 : New digital YM3812/YM3526 emulator (in the DOS version, use -noym3812opl to enable it). It doesn't support the rhythm section yet, but is overall better than the old one. [Tatsuyuki Satoh]

16th July 1999: Tatsuyuki Satoh fixed Toki YM-3812 sound.

14th July 1999: Tatsuyuki Satoh sent in a totally new YM-3812 emulator which sounds a lot better than the old one.

0.34b5 : YM3812 and YM3526 software emulator. In the DOS version it is disabled because we are using the 100% compatible SoundBlaster OPL chip. [Carl-Henrik Skårstedt] A beginning for a YM2413 emulator. It pushes data through the YM3812. [Paul Leaman, Ernesto Corvi]

0.33b7 : The YM3812 emulator still passes commands to the Sound Blaster OPL chip, but it handles timers in software. osd_ym3812_status and osd_ym3812_read removed. [Aaron Giles]

Games: Armed Formation (Nichibutsu 1988 - YM3812), Out Zone (Toaplan 1990 - YM3812), Break Thru (Data East 1986-YM-3526)

S3.12 YMZ280B

27th June 2000: Aaron Giles sent in an update to the YMZ280B sound core with much better sound output.

22nd June 2000: Aaron Giles sent in a preliminary YMZ280B sound core, adding sound to Dangun Feveron, ESP Ra.De. and Uo Poko.

S3.13 AY-8910 / AY-3-8910

0.36b15: Source: Added gain support to mixer.c, through the new MIXERG() macro (extension of MIXER()). Removed the gain filed from AY8910, YM2204, YM2610 structures.

0.35b2 : Zsolt Vasvari added Centipede (bootleg with AY8910 instead of Pokey).

0.34b2 : Tatsuyuki Satoh updated the FM emulation and the way the 8910 updates its buffers.

0.33b7 : Nicola changed the AY8910 emulation to generate three separate audio streams for the three channels instead of premixing them. This improves audio quality, increases the volume, and doesn't seem to affect performance too much.

0.31 : Tatsuyuki Satoh supported 16 bit samples in AY8910 and SN76496.

0.30 : Tatsuyuki Satoh, Fabrice Frances, Nicola Salmoria and Pete Ground completely rewritten the 8910 emulator and interface. This affects a lot of games, but the one which benefits more is Gyruss: it now plays many sound effects which were missing. Nicoal changed the way 8910 sound is updated: there's no longer a fixed "updates per frame" value defined in the driver, instead the audio is stream is generated whenever a chip register is written to (and at every vblank). This improves sound quality in several games.

0.27 : Nicola changed the 8910 sound chip emulation interface to allow updates more frequent than 60 per second. I also increased the sampling frequency to 44.1kHz. These changes provide dramatic improvements in sound quality, which you can appreciate in e.g. Gyruss and Pooyan.

0.20 : Source: Changed 8910intf to support 5 PSGs (Gyruss have them!). 8910_sh_update() doesn't emulate the 8910 audio if sound is disabled (the I/O ports of the chip are still emulated, since some games use them for input).

0.18 : Fixed bug in the 8910 emulation which caused noise to be played in Crazy Kong when you jumped over a barrel.

0.16 : Source: Nicola wrote some general purpose routines to simplify interface with the AY8910. They are in 8910intf.c.

0.13 : As promised, I modified the 8910 emulator to set the clock frequency at run time, so sound in Crazy Climber and Crazy Kong is now back as normal.

0.12 : Since the 8910 emulator doesn't allow to set the clock frequency at runtime, I temporarily switched to using the default one. This affects sound in Crazy Climber, Crazy Kong and Bagman.

0.05 : By popular demand, reverted to the old AY-3-8910 emulation code.

0.04 : New experimental AY-3-8910 sound emulation code provided by Andy Milne. This sounds better in some places and worse in others. It is used by Crazy Climber, Crazy Kong and Bagman.

0.02 : AY-3-8910 emulation by Ville Hallik and Michael Cuddy.

S3.14 Y8950

0.36b11: Y8950 emulator, used by Ginga NinkyouDen. [Tatsuyuki Satoh]

20th November 1999: Tatsuyuki Satoh added support for Delta-T ADPCM of Y8950, and he modified Ginga Ninkyouden driver to use it.

S4.0 Pokey

0.37b7 : Jürgen Buchmüller fixed the Pokey emulation so that the Tempest reset bug is fixed, this time for real and forever.

28th August 2000 : Jürgen Buchmüller modified the Pokey RNG functions to finally work as they would in real hardware.

25th June 2000 : Jürgen Buchmüller fixed the Pokey sound core, and Tempest sounds a bit better now.

0.35b2 : Zsolt Vasvari added Centipede (bootleg with AY8910 instead of Pokey).

0.34b8 : Jürgen Buchmüller improved the Pokey emulation.

0.30 : Aaron Giles make same change to the POKEY interface.

0.29 : Brad Oliver updated pokyintf.c to be more like 8910intf.c. Variable clock frequency, port callbacks, a clipping parameter, variable updates per frame. Most noticeably, Tempest has much improved sound with more frequent updates.

0.27 : Thanks to the precious information on the Pokey random number generator provided by Eric Smith, Hedley Rainnie and Sean Trowbridge, some problems with Centipede (start with 18 credits) and Tempest (hang after level 13) are now solved.Source: Brad Oliver wrote the new sndhrdw/pokyintf.c file. It handles most of the pokey interface to pokey.c. Rather than call milliped_sh_start() or whatever, call pokeyx_sh_start(), where x is the number of pokeys. It will keep track of the pokey count and use the appropriate clipping. I'm not sure 3 pokeys is a possible combination so there is no such pokey3_sh_start() routine.

0.16 : Source: Brad Oliver modified pokey.c and pokey.h to make them more portable.

0.14 : Ron Fries provided a new version of his Pokey emulator which fixes problems in the interface with the SEAL audio library (signed vs. unsigned samples).

0.12 : Sound in Centipede, through Ron Fries' POKEY emulator.

Games: Atari - Tempest (1980), Centipede (1980), Missile Command (1980)

0.35b5 : Aaron Giles merged the old and new Namco sound subsystem, and added support for stereo output.

0.30 : Nicola Salmoria and Aaron Giles completely rewritten the Namco waveform audio subsystem. This gets rid of some artefacts in Pac Man (eating a ghost) and Ms Pac Man (eating dots while a fruit is bouncing).

0.19 : Added partial sound support to RallyX (no explosions yet). Thankx to Ron Fries.

Games: Pac-Man (Namco 1980), Rally X (Namco 1980), Galaga (Namco 1981), Pengo (Sega 1982), Motos (Namco 1985)

0.30 : 8039 emulator, and _emulated_ sound in Donkey Kong, Donkey Kong Jr. and Mario Bros. Since the boards also use discrete circuits to generate sound, some samples are still needed to get complete sound support. Also partial sound in Radarscope. [Ron Fries, Dan Boris, Mirko Buffoni]

0.20 : Ron Fries created a new set of Donkey Kong samples, using Mike Cuddy's 8039 emulator. The new samples no longer have static, they are aliased and louder.

Games: Carnival (Sega 1980), Mario Bros. (Nintendo 1983), Juno First (Konami 1983), Gyruss (Konami 1983), Finalizer (Konami 1985)

S8.0 Hitachi M6803 / HD6803

0.37b1 : 6803/63701 external port writes no longer set to 1 the bits that are set as inputs in the DDR register. Instead, they are set to the value returned by a read from the port. [Tatsuyuki Satoh]

0.36b8 : Tatsuyuki Satoh finally fixed the CMPX instruction in the 680x core. On the 6800 it does not affect the C flag, on the others (6803, 63701) it does.

0.35b6 : Note: the CPU cores have been completely torn apart and rearranged in this release. Don't be surprised if a large number of games donì't work at all. For example, Twin Cobra doesn't boot, and most (all?) of the games using a 6803 lock up (ctrl-alt-del needed).

Games: Irem - Moon Patrol (1982), Tropical Angel (1983), Spelunker (1985)
