00 - Cool Camera

3With this code on, it seems you forgot to pay the repair bills. The ship will be exploding, and it will be hard to maneuver, but you can still race.
4With these 29 lines of code, press the Cheat Device button during play to send your enemies to kingdom come! They will race all right but you have the power to blow them up!
5Jody/Samurai's super pictures aren't in the memory, this just lets you drive their supercars.

Jody Summer in Supercat can only be used in Time Trial.

04 - 4th Color (Again)
05 - Hidden Color
9Try to ride off the track... You should be able to go right through the wall on one side or the other.
10Energy gets depleted as a result but boosters look awesome.
113C00 - Very Thin
3B00 - Less Thin
3D00 - Small
3D40 - Not As Small

12This slows down the game dramatically. It's still playable and music runs normally. An ideal code for people who think this game runs too fast! Lol!

000B - No Audio
000C - No Audio
000D - Very Low Bass, Very Slow Track Music
000E - No Audio
000F - No Audio
14The "Go!" sound seems to remain.
15Uses a black/white texture, like old toy race-tracks/slotcars.
16This code is good if you don't want to slide at all, but since you can't slide, the 'Z'+'R' buttons will lock the cars direction. Be careful! If you hit a wall, you'll probably be stuck on it longer. Just hit the 'A' button to get off the wall faster. Setting it all the way to acceleration won't matter you still won't slide at all.
