I don't know if there is a dedicated board for this sort of question, so since this is the game I'm concerned about using such a device with, I'll ask here. If I had a gameshark, would I be using the codebreaker code list? Or does gameshark use it's own system? Same deal with Action Replay, I don't know anything about using the devices, so I don't know where to begin as far as how to look up what codes to use depending on which device I buy.
On a related note, which device would you recommend?
