How do u activate cheat codes on sims 2 for gamecube?

You have to put in the cheat mode code during game play. It is Left, Right, Up, Left, Z. The 9,999 money cheat is Right, Left, Z, Right, Left. The unlock all recipes is Z, B, Up, Down, Right, A. The unlock all objects is Z, X, Down, Left, Up. The unlock all places is X, Z, Left, X, Up, X. Hope this helps. (just so you know you have to put in the cheat mode code in before all the other ones.
