1. download the newest cheat file like elixirdream said
2. for firmware 3.2, copy the cheat.db to your iTouch folder overwrite the old one
3. goto iGame, highlight a Game and push Select or choose the icon on the right side of the game to enter the Cheat Config screen, enable the cheats you want to use
4. choose the Checkmark to save the settings and boot the game
