Choosing your own bonus code:
Use the following trick to change your bonus code. For example, if you want to use the cheats for "1154" but number is different. Delete your game file from your hard drive, then reload the game. You will have a new bonus code. Repeat this process until you get the desired number. This usually works within about eight attempts as there are only about eight different bonus codes.
