The lower the value, the higher the gain. This works by fooling the game into thinking your characters are level ?? when it calculates experience gained. So it will be rather slower at the beginning of the game than at the end, i.e. ?? = 01 will get you 500 or so experience in the Razril back street, and later in the game, ?? = 01 may shoot you straight to level 99.

Replace ## with the quantity you want, and replace ???? with the digits from the Item Digit List at CMGSCCC.com. For both item codes to work, you'll need to move about in game for a bit. The effects will not be immediate, but they will appear within about twenty seconds after loading a save.
