Blast Corps

Instant Explosion Cheat:
Simply drive up next to something and try to get out of your vehicle by using the Z button.
If you're too close, your man will yell and not get out. If you continue holding the Z button,
the obstructing object will blow up like magic.

Turbo Start:
You can get a turbo start on timed events by pressing the acceleration button on the last "beep" just as the light turns green. You must time it perfectly for it to work.

Ghost Riders:
When your in a level where you are going around a race course, after you finish the number of laps it says to do, do the race again with another vehical. Now when you start, you'll be racing a ghost car. The ghost car will be the vehical that you just used and will do everything you did in the last race (like in Mario Kart).
