TODO:

* Wanted: 317-0067 FD1094 CPU


Bugs:

- altbeast6, altbeastj: Music does not stop when the sequence of transformation begins. abelardator2 (ID 04022)

- altbeast5, altbeastj: Background graphic does not appear. abelardator2 (ID 03645)


WIP:

- 0.181: Dumped I8751 317-0078 at location C2 for parent set altbeast. Also renamed the mc8123 regions to 'mc8123' instead of 'mcu' because it was confusing [CAPS0ff]. Sound improvements for clones Altered Beast (Datsu bootleg) and Mutant Warrior (Altered Beast - Datsu bootleg). Hook up MSM5205 and 74LS157, games now have some imperfect samples playback [ARJ].

- 9th December 2016: CAPS0ff - Decapped, deprotected and dumped Altered Beast 8751: 317-0078.2C. The basic idea is to erase the security fuse without erasing the EPROM content. From previous experiments, the fuse is known to be near the top middle of the die, reasonably far from the EPROM. So by masking the EPROM with a UV opaque material and erasing, the 8751 is de-protected and can simply be read out.

- 0.180: David Haywood fixed missing graphics in the crystal ball of clones altbeastj and altbeast6.

- 0.175: gmx and The Dumping Union added clone Mutant Warrior (Altered Beast - Datsu bootleg). Osso added preliminary sound to clones Altered Beast (Datsu bootleg) and Mutant Warrior (Altered Beast - Datsu bootleg).

- 0.166: David Haywood added clones 'Altered Beast (set 5) (bootleg of FD1094 317-0069 set)' and 'Juuouki (set 3, Japan) (bootleg of FD1094 317-0068 set)'.

- 0.164: O. Galibert fixed clone Altered Beast (set 2, MC-8123B 317-0066) encryption.

- 0.154: Chris Hardy and Andreas Naive reconstructed the SEGA FD1094 key for clone Juuouki (set 1, Japan, FD1094 317-0065) - Game now playable. Note: Some of the RNG-independent bits could be incorrect.

- 0.150: Barry Harris hooked up gfx writes properly in clone Altered Beast (Datsu bootleg).

- 0.148u5: ANY added clone Altered Beast (Datsu bootleg).

- 0.145u2: Stefan Lindberg, Chris Hardy and The Dumping Union added missing FD1094 key to Juuouki (set 5). Now that the FD1094 key has been supplied we see it's actually Altered Beast. Changed description of clone 'Juuouki (set 5, Japan, FD1094 317-0069)' to 'Altered Beast (set 5, FD1094 317-0069)'. Renamed (altbeast5) to (altbeast6) and (altbeastj2) to (altbeast5).

- 0.138u4: Stefan Lindberg and The Dumping Union added clone Juuouki (set 5, Japan, FD1094 317-0069). Changed description of clones (set 5, 8751 317-0076) to 'Altered Beast (set 6, 8751 317-0076)', (set 7, 8751 317-0078) to 'Altered Beast (set 8, 8751 317-0078)' and 'Juuouki (set 6, Japan, 8751 317-0077)' to 'Juuouki (set 7, Japan, 8751 317-0077)'.

- 10th July 2010: Smitdogg - We got Altered Beast (317-0078) for decapping.

- 0.133u1: Renamed (aliensy3) to (aliensyn3), (altbeasj) to (altbeastj), (altbeas5) to (altbeast5), (altbeas4) to (altbeast4), (altbeaj3) to (altbeastj3), (altbeas2) to (altbeast2) and (altbeaj1) to (altbeastj1).

- 28th July 2009: Mr. Do - I got some work done myself: Altered Beast artwork, from the BYOAC/CAG artwork.

- 0.113u3: Nicola Salmoria added proper MC8123 decryption code and MC-8123B 317-0066.key to clones Altered Beast (set 2), (set 3) and (set 4).

- 0.112u2: Properly idenitified sound ROMs for clone Altered Beast (set 2, MC-8123B 317-0066) [Brian Troha].

- 0.111u1: Alex Jackson fixed a miscompilation issue with GCC4 that was first noticed in Altered Beast but also affected Moonwalker, Galaxy Force 2 and probably many other games.

- 0.103u4: David Haywood fixed graphics banking in 8751-based Altered Beast sets.

- 0.97u1: Changed clones description to 'Juuouki (set ...)'.

- 0.95: Nicola Salmoria fixed some Altered Beast sets. The sets were a mess. Some of them were using the wrong version of the gfx ROMs (that's why they had to be loaded in a strange way). Should be correct now.

- 0.94u5: Changed description of clones Altered Beast (set 1, 3 and 6) to Jyuohki (set 1, 3 and 6).

- 16th February 2005: 3D ARCADE - New 3D cabinet model for Altered Beast from Bond1.

- 0.92: Changed clone (Version 1?, 8751 317-0078) to parent 'Altered Beast (set 7, 8751 317-0078)', (Version 1, MC-8123B 317-0066) to clone 'Altered Beast (set 2, MC-8123B 317-0066)', (8751 317-0076) to 'Altered Beast (set 5, 8751 317-0076)', (Version 2, MC-8123B 317-0066) to 'Altered Beast (set 4, MC-8123B 317-0066)', 'Jyuohki (Japan, 8751 317-0077)' to 'Altered Beast (set 6, Japan, 8751 317-0077)', 'Jyuohki (Japan, 8751 317-0077)' to 'Altered Beast (set 1, Japan, FD1094 317-0065)' and 'Jyuohki (Japan, FD1094 317-0068)' to 'Altered Beast (set 3, Japan, FD1094 317-0068)'. Renamed (altbeast) to (altbeas2), (altbeasa) to (altbeast), (altb8751) to (altbeas5), (altbeas2) to (altbeas4), (jyuo8571) to (altbeasj), (jyuohki) to (altbeaj1) and (jyuohki2) to (altbeaj3).

- 0.89u6: MC8193 update [Nicola Salmoria]. The table for 317-0066 (Altered Beast) are almost complete, but there are still some uncertain values for opcodes above 8000 (not actually needed).

- 0.89u3: Decryption of MC-8123B 317-0066 encrypted Z80 used by Altered Beast (Version 2) [Nicola Salmoria, Dave Widel]. Aaron Giles updated some game info against Thierry's spreadsheet; altbeast needs an encrypted Z80 for sound now. Changed description to 'Altered Beast (Version 1, MC-8123B 317-0066)' and clone (Version 2, unprotected) to 'Altered Beast (Version 2, MC-8123B 317-0066)'.

- 0.89u2: Added I8751 (8MHz) MCU to altbeasa, altb8751 and jyuo8751. Changed description of clones 'Altered Beast (8751 317-unknown)' to 'Altered Beast (8751 317-0076)', 'Jyuohki (Japan, FD1094 317-unknown)' to 'Jyuohki (Japan, FD1094 317-0065)' and 'Jyuohki (Japan, 8751 317-unknown)' to 'Jyuohki (Japan, 8751 317-0077)'.

- 0.88u7: Added clone Altered Beast (Version 1?, 8751 317-0078). Added new cpu1 roms and FD1094 key to clone Jyuohki (Japan, FD1094 317-0068). Changed parent description to 'Altered Beast (Version 1, unprotected)' and clone (Version 2) to 'Altered Beast (Version 2, unprotected)'.

- 0.88u6: Added clone Jyuohki (Japan, FD1094 317-0068). Changed description of clones 'Altered Beast (8571 protected)' to 'Altered Beast (8751 317-unknown)', 'Jyuohki (Japan)' to 'Jyuohki (Japan, FD1094 317-unknown)' and 'Jyuohki (Japan, 8571 protected)' to 'Jyuohki (Japan, 8751 317-unknown)'. Changed Z80 CPU2 clock speed to 5MHz and palettesize to 6144 colors.

- 11th November 2004: Chris Hardy - Dumped cpu 317-0068, one of the Japanese Altered Beast sets, it seems to work correctly.

- 0.84u5: Fabrice Arzeno added clones Altered Beast (8571 protected) and Jyuohki (Japan, 8571 protected).

- 15th March 2004: Charles MacDonald cleaned up altbeast, riotcity, bayroute and aurail (no junk in error logs, took care of unused inputs/outputs, etc).

- 15th February 2004: Dave Widel emulated the sound CPU encryption in Altered Beast (set 2), though it breaks all the other games.

- 0.36b15: Added clone Jyuohki (Japan).

- 0.36b1: Andrew Prime added Altered Beast (Version 1). Changed 'Altered Beast' to clone 'Altered Beast (Version 2)'. Renamed (altbeast) to (altbeas2).

- 0.35b2: uPD7759 support in Altered Beast [Howie Cohen].

- 0.34b4: Sound in all of the working System 16 games [Phil Stroffolino]. Added Z80 (4096000 Hz) CPU2 and YM-2151 (4096000 Hz) sound.

- 0.33b3: Mirko Buffoni added 'Altered Beast' (Sega 1988).
