I don't know if my Cubis game qualifies as a real program, but I do bankswitching like: CMP $F0xx ; xx is the control byte NOP CMP $FFF8 but LDX controlbyte CMP $F000,X CMP $FFF8 should also work. Of course you need to make sure, that you are not moving the bank away, that contains this code, without having some sensefull code on the same ROM address in the bank, that you are moving in. I hope this helps a bit, or what exactly is your problem with your program. Ciao, Eckhard Stolberg p.s. Chrissalo did a pretty good text on Supercharger bankswitching and RAM access. Maybe he can send you a copy. -- Archives available at http://www.biglist.com/lists/stella/archives/ E-mail UNSUBSCRIBE in the body to stella-request@xxxxxxxxxxx to be removed.
