0.36RC1 [Quench]


- Whoopee/Teki Paki sometimes tests bit 5 of the territory port just after testing for vblank. Why ?

- Whoppee is currently using the sound CPU ROM (Z80) from a differnt (pirate ?) version of Pipi and Bibis (Ryouta Kikaku copyright). It really has a HD647180 CPU, and its internal ROM needs to be dumped.

- Fix top character text layer (implement the line position table).

- Priority problem on 2nd player side of selection screen in FixEight (both original and bootleg)

- Fixeight bootleg text in sound check mode does not display properly with the CPU set to 10MHz (ok at 16MHz). Possible error in video_count_r routine.

- Need to sort out the video status register.

- Batrider IRQ4 beig activated at EOF is rubish. It's sound related - maybe acknowledgement from the Z80 when its NMI has completed (port 46)


- Teki Paki: Working, but no sound. Missing sound MCU dump. Chip is protected. It's a QFP80 Hitachi HD647180.

- Ghox: Working, but no sound. Missing sound MCU dump. It's a QFP80 Hitachi HD647180.

- Dogyuun: Working, but no sound. MCU type is likely a NEC V25+. Chip is a PLCC94 stamped 'TS-002-MACH'.

- Knuckle Bash: Working, but sound FX only (missing music). MCU type is a NEC V25+. Chip is a PLCC94 stamped 'TS-004-DASH'. Some PCBs use another version stamped 'NITRO' which is the same chip type.

- Truxton 2: Working.

- Pipi & Bibis: Working.

- Whoopee : Working. Missing sound MCU dump. It's a Hitachi HD647180. Using bootleg sound CPU dump for now.

- Pipi & Bibis (Ryouta Kikaku): Working.

- FixEight: Not working properly. Missing background GFX, and sound FX only (missing music). Both controlled by MCU. MCU type is a NEC V25+. Chip is a PLCC94 stamped 'TS-001-TURBO'

- FixEight bootleg: Working. One unknown ROM (same as pipibibi one). Region hardcoded to Korea (@ $4d8)

- Grind Stormer: Working, but no sound. MCU type is a NEC V25+. Chip is a PLCC94 stamped 'TS-007-SPY'.

- VFive: Working, but no sound. MCU type is a NEC V25+. Chip is a PLCC94 stamped 'TS-007-SPY'.

- Batsugun : Working, but sound FX only (missing music) and wrong GFX priorities. MCU type is a NEC V25+. Chip is a PLCC94 stamped 'TS-007-SPY'.

- Batsugun Sp': Working, but sound FX only (missing music) and wrong GFX priorities. MCU type is a NEC V25+. Chip is a PLCC94 stamped 'TS-007-SPY'.

- Snow Bros. 2: Working.

- Mahou Daisakusen: Working.

- Shippu Mahou Daisakusen: Working.

- Battle Garegga: Working.

- Armed Police Batrider: Working.

- Battle Bakraid: Working.


- Raizing games and Truxton 2 are heavily dependent on the Raine source. Many thanks to Richard Bush and the Raine team.

- See Input Port definition header below, for instructions on how to enter pause/slow motion modes.

- Code at $20A26 forces territory to Japan in V-Five. Some stuff NOP'd at reset vector, and Z?80 CPU post test is skipped (bootleg ?)

- sstriker: Might be a bootleg / hack, the region jumper is read with this set but even when set to Japan you get all english text etc which seems a little odd, but might be correct.

- kingdmgp: Might be a bootleg / hack, some of the tiles needed for the credits screen have been stripped out, doesn't seem very professional, since its rare and should probably only have a different graphics rom its nearly impossible for us to verify, a lot of boards being sold as 'Kingdom Grand Prix' are infact conversions using Neill Corlett's hack.


- Hack is needed to reset sound CPU and sound chip when machine is 'tilted' in Pipi & Bibis. Otherwise sound CPU interferes with the main CPU test of shared RAM. You get a 'Sub CPU RAM Error'.

- What do Scroll registers 0Eh and 0Fh really do ????

- Snow Bros 2 sets bit 6 of the sprite X info word during weather world map, and bits 4, 5 and 6 of the sprite X info word during the Rabbit boss screen - reasons are unknown.

- Fourth set of scroll registers have been used for Sprite scroll though it may not be correct. For most parts this looks right except for Snow Bros 2 when in the rabbit boss screen (all sprites jump when big green nasty (which is the foreground layer) comes in from the left)

- Teki Paki tests video RAM from address 0 past SpriteRAM to $37ff. This seems to be a bug in Teki Paki's vram test routine !

- Batsugun, relationship between the two video controllers (priority wise) is wrong and unknown.


- The Toaplan 2 hardware with V25+ secondary CPU controls the sound through to a YM2151 and OKI M6295 on some boards. Here we just interperet some of commands sent to the V25+, directly onto the OKI M6295. These tables convert commands sent from the main CPU, into sample numbers played back by the sound processor. The ADPCM ROMs contain intrument samples which are sequenced by the sound processor to create some of the backing tracks. This is beyond the scope of this playback file. Time would be better spent elsewhere.


- 0.111u2: Brian Oberholtzer corrected some incorrect dipswitch information in the toaplan2 driver.

- 0.109u1: Corrado Tomaselli converted all the toaplan2.c games to mono since the PCBs are JAMMA without external stereo connectors.
