New games marked as GAME_NOT_WORKING
------------------------------------ Miracle Derby - Ascot [Stefan Lindberg, David Haywood] Date: Thu, 22 Oct 2009 19:03:48 +0100 From: David Haywood <neohaze@nildram.co.uk> CC: Philip Bennett <p.j.bennett@gmail.com> Subject: Re: Miracle Derby Well here is some initial rom loading, gfx decode, palette decode. I haven't mapped the CPUs yet, but I imagine it will end up using mostly the home data code in the end (although that seems to have game specific code for a lot of games anyway, so there are probably some issues with that driver) You can check this in for now, and it can be returned to later.

/* Miracle Derby - Ascot
|
||||
|
||||
- has the same GX61A01 custom (blitter?) as homedata.c 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.c should be looked at.

|
||||
Notes from Stefan Lindberg:
|
||||
|
||||
Eprom "x70_a04.5g" had wires attached to it, pin 2 and 16 was joined and pin 1,32,31,30 was joined, i
|
||||
removed them and read the eprom as the type it was (D27c1000D).
|
||||
|
||||
Measured frequencies:
|
||||
MBL68B09E = 2mhz
|
||||
MBL68B09E = 2mhz
|
||||
z80 = 4mhz
|
||||
YM2203 = 2mhz
