This board uses the well known 052109 051962 custom gfx chips, however unlike
|
||||
all other games they fetch gfx data from RAM. The gfx ROMs are memory mapped
|
||||
on cpu B and the needed parts are copied to RAM at run time.
|
||||
To handle this efficiently in MAME, some changes would be required to the
|
||||
tilemap system and to video/konamiic.c. For the time being, I'm kludging
|
||||
my way in.
|
||||
There's also something wrong in the way tile banks are implemented in
|
||||
konamiic.c. They don't seem to be used by this game.
