Ridge Racer - PS

Wave the Flag:
At the title screen hold R1, R2, L1, and L2 and move the flag with the d-pad and the buttons.

Black Car:
Beat the Time Trial Bonus Track to get the black car.

More Cars:
Beat the arcade game at the loading screen and you will get a whole new selection of cars.

Mirrored Tracks:
Right after the race has started, turn around and drive straight into the brick wall. There will be a sign on the top of your screen that says wrong way but ignore it, and keep driving straight into the wall. Then it will take you into the first tunnel except it will be a mirror version of the entire track.
