Cheat codes
To use these cheat codes, type them in during a race (except the MONEY code, which must be typed while in the Upgrade menu). If you pause the game by hitting P, you can type in the cheats while the game is paused. Typing SLIPPERY, of course, will unpause and then pause the game again, so try to type it fast. Another good time to enter a code is after the loading screen, just before the track announcer shouts, "Go!"
