For a really thorough, succint 6502 reference card (pretty much all someone with your experience will need), grab this: http://www.spies.com/arcade/simulation/cpuRefCards/6502 The VCS.H is a file of equates translating the Stella register and port mnemonics to the correct $## memory addresses. That way your code will have lots of COLUPF and GRP0 arguments and be nice and readable by practically no one ;) You can make your own in about 10 minutes if you type fast, though I'm sure someone will email it to you any minute now! > I'll worry about stuff like production, distribution method, pricing, and > so on when I actually make something that works =) Good luck! -- mor@xxxxxxx http://www.crl.com/~mor/ -- To unsubscribe, send the word UNSUBSCRIBE in the body of a message to stella-request@xxxxxxxxxxx
