The Action Replay (AKA AR) is a separate device that you have to purchase for your GameCube...
I don't know how old you are, so I don't know if you remember the Game Genie, but it's like that...
Don't feel dumb, I didn't know what it was either for a while and I still don't have one yet...
So they aren't Codes that you can just use in the game unfortunately =(
