Re: A whole rom board gone bad?

By the way, since I'll need to reprogram a whole set of roms. Are there
any major differences between Rev. A and Rev. C of Space Fury. Rev. C
seems to require two extra roms, but the only difference I can see is Rev.
C has 'Sega <c> 1981' printed on the screen. I'm sure it doesn't require
two extra roms to print that logo.

Just curious.
