Create a license plate with any one of the names listed below to turn into a different character. Before confirming the name make sure that OK is lighted then hold L + R then confirm your plate name.
At the licence plate entry screen, hold R+L, and press up or down on the control stick. One of the wavering bars will change colors. Keep pressing up or down to scroll through many different colors. When the bar is your desired color, hit OK. Nick's car will be the color of the wavering bar.
Enter these on the map screen and not during gameplay:
When you accidently (or purposely) flip your car upside down, the game counts this as ''Air Time''. It is possible to get massive air time by simply lying upside down then getting back on your wheels.
To get back on your wheels, you must first have the Peel-out upgrade, where you must hold accelerate and brake together for a boost. While upside down, you will still be able to use this ability, so constantly do this until your car flips itself over again. Once you do this, the game registers this as your car returning to it's ''feet'', and gives you the appropriate air time!
Use the C-Stick on the main menu to scroll the monochrome city background forward and backward at will.
