Flying cars: Enter the "Enable UFO" code, then the "Change cars" code. Select the UFO as a vehicle, then use the D-pad to change to a car when game play begins. Your car will be flying like the UFO. Note: The reverse is also true. This trick actually allows you to use the physics and "win screen" of the car you selected. For example, if you select the RG1 as a car, then use the Probe UFO, you will fall like a rock (with the RG1 physics).
