Game Shark Codes

Get into any type of game -- it doesn't matter. Do anything in the game, with anybody, and
then get it so that you can substitute players into the game. After you substitute the
players in, go to replay mode and go back to any point in the game where you had the
original players in. Say you had Shaq in, and he did a monster dunk, and then you
substituted Dickey Simpkins (bad player) in for Shaq. In replay mode, Dickey would be
doing the monster dunk Shaq had been doing, even though he hadn't been in the game!
