According to the 4256041 schematics, page 15, the enable signal for the sram, called _VIDMATICS_, is enabled when A15, A14 and A12 are high and A13, A11 and A10 low, ie $D000-$D3FF That wouldn't overlap with $0/$1. > You can't do sprites or chargen/bitmap in bank f, it's real nasty. Well, the limit is that you can only access 1k in bank F, but there seems to be no special limit on the usage of that 1k. Usually it's probably best to use it for screen ram but in theory you could store sprite data there instead, or whatever you want to have there. -- (\_/) Copy the bunny to your mails to help (O.o) him achieve world domination.
