For all of these codes to work you need to first enter the code called Cheat Gnome, or else none of them will work. The cheat gnome is a silver post (it has the same dimond thing at the loading screen on top of it.)Go up to the cheat gnome,it should be in your front yard, and enter the code you want. You will need to enter these in 5 seconds or less for them to work.If you want to get rid of the cheat gnome then just re-enter the cheat gnome code. I have used all of these cheats before so I know they work. Happy Cheating!!!!!:)
