No, there are no cheat codes for Kingdom Hearts 2, but there is something you can buy that's called Action Replay. with it you can change the codes in the game and mod just about everything (so you can play as Roxas in his Organization XIII uniform rather than Sora.) also with Action Replay you can have your group be Axel, Roxas, and Demyx in place of Sora, Donald and Goofy.
Buy ActionReplay or GameShark and find some codes.
