MANN, OH-MANN
199? - MERKUR
Preliminary driver by Roberto Fresca.
German board game similar to Ludo, derivated from the indian game Parchisi.
Coin-operated machine for 1-4 players. No screen, just artwork and lamps.
The machine was designed for pubs, etc...
Field: 93 cm.
High: 105 cm.
1x keylock.
Accept DM and Euro.
It's all a challenge. Even once emulated, the game will need a lot of
artwork and lamps work...
Currently sits in a loop between 0x100000 and 0x600006 addresses r/w,
the snippet is there:
001BB8: move.b (A2), D0
001BBA: jsr $6dc0.l
001BC0: tst.b D0
001BC2: bne $1bb8
Passing this loop it checks the i/o stuff, including the sound addresses
