I am writing my own NES emulator and have a few questions.
1: Most of the documentation I have read says that "negative numbers are hardly ever used", how do I know which variables/registers should contain signed numbers, or if all of them can, then when do they?
2:Can someone give me an efficient and simple way of implementing the ROR/ROL opcodes? The way I'm doing it is sortof crappy and I don't think it's coming out right.
Thanks ,
Silly Ramone
