I'm not sure if I'm missing anything incredibly obvious, or if something just isn't working for me, but I can't find a place in FCEUX to view the direct input of 6502 ASM code to reverse engineer on the NES. By this, I mean view the commands sent to the registers from the game. As a simple example: LDA #57 Is there a way to do this kind of thing in FCEUX, and if so, how do I get to it? EDIT: On second thoughts, this would most likely have been better off in the FCEUX or general subforums.

The thing you're looking for is called Debugger. Another choice would be the Trace logger.

Thanks. I guess when I ran them I just failed to recognise them as what they were xD

Warning: When making decisions, I try to collect as much data as possible before actually deciding. I try to abstract away and see the principles behind real world events and people's opinions. I try to generalize them and turn into something clear and reusable. I hate depending on unpredictable and having to make lottery guesses. Any problem can be solved by systems thinking and acting.

Hex editors are useful for finding certain "triggers", FCEUX by far has the best hacking tools i've saw...but as for assembly code, that's a tough one...i'm only starting to learn how to tinker with programs/roms. I've typed random stuff into debuggers to see what happens and it's great comedy breaking games, further than that, i'm afraid i don't know enough yet, sorry man

personally, i'd love to take a game to bits and find out what's happening, but it'd be like deciphering the da vinci code or something, i wouldn't know where to start, though i'm famiiar with hex, i might try this. good luck
