0.128u7 [David Haywood, Angelo Salese]


< Japan >


WIP:

- 0.135u3: Fabio Priuli added driver data struct and save states to '4nin-uchi Mahjong Jantotsu'.

- 0.131u3: Angelo Salese fixed ADPCM stop flag in Jantotsu, and cleaned up some routines in the driver. Added an heuristic table for the MSM samples. Fixed MSM frequency. This fixed game gives incorrect sound calls. Fixed ADPCM roms addresses. Changed MSM5205 clock speed to 384000 Hz.

- 0.129u2: Angelo Salese hooked up ADPCM sound to Jantotsu, it plays something but it's not yet right. Added MSM5205 (288000 Hz) sound. Changed region gfx1 to adpcm.

- 0.128u7: David Haywood and Angelo Salese added '4nin-uchi Mahjong Jantotsu' (Sanritsu 1983).

- 16th December 2008: Angelo Salese - Me, Haze and Phil Bennett just wrote another driver for a 1983 Sanritsu game named 4nin-uchi Mahjong Jantotsu. It uses 4 256x224 1bpp bitmaps all banked on the same ram area.
