Double Trouble
If you hold down the L1, Triangle and X button, whilst pressing up on the joypad, as the game loads, you should get two ships during the Galaga game, rather than one. Side by side, these give you twice as much firepower and twice as much chance of completing the game and accessing the bonus cars.

Mirror Mode
To race on a track that is the mirror image of the normal one, after the start of the race, turn around. On the normal tracks this must be before you get onto the main straight. On the extra courses this must be before you get the first bend. Now accelerate as fast as possible and drive through the brick wall in front of you. You'll now be able to carry on around the track, but what was a right hand turn will have become a left one and what was a left turn, will have become right. Novel, eh?

Flag Tricks
Whenever you start a race, you will see a chequered flag waving in the wind. If you hold down the L1, L2, R1 and R2 buttons and press the D-padyou can make it flip and rotate in different directions. Alternatively,you can press the X button to zoom in on it and the Square button to zoomaway from it. Pressing start as well, will also make the flag go transparent.Remember though, the L1, L2, R1 and R2 buttons have to be held down throughout for these tricks to work.

Mirrored Courses
As soon as you begin a race, turn around so you are facing the wrong way. There is a barrier there. Bump into it about three times and the screen flashes and you are where you were at the beginning of the race. The course will be a mirror image of the original course and all the check point signs will look like they are being looked at through a mirror. This works in multiplayer races as well!
