st0016.c

0.81u6 [Tomasz Slanina]


TODO:

- Find NMI source, and NMI enable/disable (timer ? video hw ?)

- Not working games: Super Real Mahjong P5 and Super Eagle Shot (RAM 0x0a000000 - 0x0a003fff (8bit) is shared with ST-0016 ($f000-$ffff) after boot, r3000 writes there "KCUFUOY" , and ST-0016 "YOU!" )


NOTES:

- Hardware: Seta custom ST-0016 chip based games.


WIP:

- 0.105u5: Tomasz Slanina fixed a couple of gfx bugs in st0016 video emulation.

- 8th March 2006: Tomasz Slanina - Fixed a lot of bugs in the ST-0016 drivers.

- 0.104u4: Aaron Giles fixed bug in ST-0016 driver (driver is broken whenever it attempts to play a sound. st0016_0104u3red).

- 0.85u3: Added 'Service Mode' dipswich.

- 0.84u5: Tomasz Slanina added 4bpp/8bpp tilemaps in the ST-0016 driver.

- 0.81u7: R. Belmont and Tomasz Slanina added ST-0016 stereo sound to the ST0016 driver. Neratte Chu and Renju Kizoku now have sound.

- 20th April 2004: R. Belmont - Further improved the ST-0016 sound, with some tips from Dox. All known features are now supported, and all 3 games that we can get to make noise sound quite nice. (The chip itself's not real powerful, but hey).

- 19th April 2004: R. Belmont - Got addicted to Neratte Chu, and that lead to reverse-engineering and hooking up sound and music for the ST-0016. Haze pointed out one critical detail I was missing, and now it sounds pretty good!

- 18th April 2004: Tomasz Slanina - Some ST-0016 fixes with a hack to get Mayjinsen 2 booting without v810 emulation (2nd cpu is used only(?) for computer AI (shougi)). Also partially emulated sprite 'rows' (similar to SSV ones) and text in Neratte Chu test mode and backgrounds in Mayjinsen 2.
