Miracle Derby - Ascot
- has the same GX61A01 custom (blitter?) as homedata.cpp and a 'similar' CPU setup (this has more CPUs)
and similar board / rom numbering (X**-)
TODO:
- Game pukes if more than one key is pressed, and MAME input defaults for 2p side
clashes with the remapped p1 keys.
For now user has to workaround by mapping p2 keys manually,
actual fix would be to define a horse betting layout in MAME input defs.
Old Haze note:
- has the same GX61A01 custom (blitter?) as homedata.cpp and a 'similar' CPU setup
(this has more CPUs) and similar board / rom numbering (X**-)
The drivers can probably be merged later, although the current per-game handling of the blitter in
homedata.cpp should be looked at.
