I have a little NES programming experience. The 6502 assembler I use is NESASM, which is also the one those tutorials recommend. There are others called Asm6 and CA65 that I haven't tried.

The syntax that each assembler recognizes is slightly different so source code that assembles properly in one assembler may not assemble properly in another. This is something to watch out for when looking at code examples on the nesdev.com forums.

HAVE FUN with NES programming! :) I've only ever made simple programs. However, the only limits are your imagination. The homebrew game "Battle Kid: Fortress of Peril" was created recently, which is one of the best NES games in my opinion.
