hopefully someone here will know..... I'm working on a cadash jamma pcb board... everything displays fine except for the sprite layer, all the graphic tiles are just blocks of a single color.... any clues?

Are you sure the graphic roms have data on them? It sounds like they're empty (but, at the same time, they shouldn't be a single colour, as that would mean they were wiped with a constant bit value, rather than electronically random)

we wiped em and re-flashed them... got an eprom eraser and a flasher too so we're positive the eprom chips have the data on them. that was our first guess....

Chances are the board is toast. It sucks, but that's the way life goes. I picked up a Racin' Force upright for $175 because the road only ever displays intermittently, but I might end up sending it off to be dumped in case it's an alternate romset and hope that it also ends up getting fixed.

most likely he means everything.
