Sound Chips : OKI6295 (@ 1.5 Mhz)

- SOURCES -

Game's rom.

MAME Info:

0.113u3 [?]

WIP:

- 0.135u2: Fabio Priuli added save state support to Mahjong Dunhuang.

- 0.121: Vas Crabb fixed dipswitches and updated DIP locations in Mahjong Dunhuang.

- 0.114u1: Luca Elia fixed Mahjong Dunhuang - Game now playable. Fixed gfx1/2 rom loading and dipswitches. Added YM2413 (3579545 Hz) and AY8910 (1500000 Hz) sound. Changed visible area to 496x224.

- 10th April 2007: Luca Elia - I rewrote the skeleton driver dunhuang.c (it used to only decode the graphics) and the hardware turned out to be pretty straightforward, just tilemaps, but with a few interesting bits: Most notably, it's able to draw a block of tiles with a single command, and to stream the tile indexes from the graphics roms. This explains why some tiles seem bad when shown by MAME's built-in tile viewer (those are data segments, not pixels).

- 0.113u3: Added Mahjong Dunhuang (Unknown 199?).
