My 6 year old son is "wearing me out" to enter the cheats we found for this game. We have PS2 version. All the instructions we have come across say "Enter Cheats at MAIN MENU Cheat Codes. Well....Everytime I power up the game there is NO MAIN MENU or Cheat Code option. It just goes to other options like Campaign and game set up and so on. I have clicked and scrolled through all of them and NO MAIN MENU OR CHEAT CODES Options to be found..... PLEASE HELP!!!!
