Hi, I've been doing some researching about the mos 6502 and I already know that the Nes CPU is a Ricoh 2A03, a processor with a 6502 core but with some modifications. I've been looking the schematics of the NES and found that the NES CPU has at least 5 pins the original 6502 doesn't. Could anyone tell me about this, what are the functions of these pins?
And something else. Could anyone show me how to work with the NES pad alone, would it be enough to just send a pulse to the latch and then what?
Thanks for the helping!
