- SOURCES -
Game's ROM.
MAME Info:
0.141u1 [Luca Elia]
0.135u1 [Luca Elia, Guru, The Dumping Union]
< Taiwan >
TEST MODE:
- Press A + B during test mode for sound test (B1+B2+B3 when using a joystick).
- Test mode is accessed by keeping test pressed during boot (as usual), but pressing F2+F3 in MAME does not actually work. It does work if F2 is pressed in the debug window at boot, and held while closing it.
WIP:
- 0.141u1: Luca Elia added Mahjong Man Guan Da Heng (Taiwan, V125T1). Renamed (mgdh) to (mgdha).
- 0.135u2: Luca Elia implemented missing joystick mode in 'Mahjong Man Guan Da Heng' and fixed inaccurate donden graphics.
- 0.135u1: Luca Elia, Guru and The Dumping Union added Mahjong Man Guan Da Heng (Taiwan, V123T1) (IGS 1997). Luca Elia decrypted Mahjong Man Guan Da Heng (Taiwan, V123T1).
- 11th October 2009: Luca Elia - The new batch of dumped IGS games made me look again at emulating the IGS031 custom ASIC. It's the graphics processor used by several titles from the late nineties (currently scattered in the igs_m68.c, igs_m027.c and tarzan.c drivers, as non-working). I started with Mahjong Man Guan Da Heng, decrypting the program rom, and noting a striking similarity with an igs017.c game I emulated before. Then everything fell into place. Remaining issues on this titles is some protection I haven't really had the time to investigate yet. That's all I could do for the moment. The remaining sets on the mentioned drivers are either still encrypted (gfx & program), protected by an ARM CPU, or incomplete dumps (i.e. the Tarzan and Super Tarzan sets). Thanks to Guru, Dyq, Bnathan, Pierpaolo Prazzoli and The Dumping Union.
