0.35b9 [Nicola Salmoria]
Bugs:
- yamato, yamato2: Original PCB screen shot for reference. Smitdogg (ID 03809)
WIP:
- 0.173: Replaced Z80 CPU1 with Z80 SegaCrypt.
- 0.166: Osso fixed Yamato crashed after INSERT COIN and graphics glitches in attract mode. Note: Yamato has one more ROM at 0x7000 - 0x7fff that must be taken care of. I opted for using the same decode for clone Yamato (World?) too, even if 0x6000 was enough for it, to avoid more code duplication.
- 0.123u3: Zsolt Vasvari merged Yamato driver with Crazy Climber and cleaned up the video driver, mainly via tilemap conversion. Fixed gfx1 rom address to $2000.
- 0.118u6: Aaron Giles fixed crash after exiting the game.
- 0.102u5: Changed region cpu1 ($f000) to user1. Changed palettesize to 352 colors.
- 17th December 2005: Tomasz Slanina added temporary BG gradient (bad colors/offset). Gradient table are stored in two(?) ROMs. Each table is 256 bytes long: 128 for normal and 128 bytes for flipped screen. Color format is unknown - probably direct RGB mapping of 8 or 16 (both roms) bits. Also table selection source is unknown.
- 18th November 2005: Tomasz Slanina - Trying to add missing background, but colors are guess.
- 0.97u4: ShimaPong added 'Bonus Life' dipswitch.
- 0.69: Angelo Salese removed a graphic rom loading kludge in Yamato, which caused a bad gray square when launching missiles. Also fixed crashes in clone Yamato (World?). Fixed gfx2 roms addresses.
- 0.67: Changed description to 'Yamato (US)' and clone (set 2) to 'Yamato (World?)'.
- 0.35b9: Nicola Salmoria added 'Yamato (set 1)' (Sega 1983) and clone (set 2). Preliminary. TODO: Two ROMs are not used, don't know what they are.
- 27th March 1999: Nicola got correct colors to Yamato.
- 26th March 1999: Nicola decrypted the last old Sega game, Yamato.
