6502SIM is a 6502 processor simulator for MSDOS that can be used as a tool for developing and testing generic 6502 code. It also makes a good platform for learning 6502 programming since you can easily watch the execution of the code and observe the results. 6520sim displays a disassembly of memory, the CPU registers, stack, and memory and theses are all updated dynamically as the code is executed so you can watch the results.

Since this is an NES Site and not a 6502 hacking/programming site I have included only a portion of the total 6502 information available on the web. If you're truly interested in the 6502 for whatever reason feel free to E-mail me. Those seeking further info on the 6502 should head in the direction of Stephen Judd's The Fridge, which is one of the most comprehensive 6502 information sites I've seen on the net.
