Winding Heat Cheat Codes for Arcade

Extra Cars
Select your course with the accelerator and don't release the pedal. At the car select screen, shift "UP" on the gearshift, you'll drop down to another set of 3 cars. "DOWN" on the gearshift will return you to the regular cars ("UP" as in gear-up, and not physically up, but don't worry, if you shift the wrong way nothing will happen.
