Nascar Heat 2002 Cheats

Enter A single race at Watkins Glenn and then start a practice session.
go out of the pits like you normally would but take a left and go
backwards just as you come out. At the beginning of the front stretch
turn around and go in the regular direction. just at the end of the
front stretch, there is a grass patch. Turn onto this patch at full
speed and you will fly into the air. If you have turned at the right
spot then you will fly over the fence and into a secret place. (just
make sure that when you hit on the other side that you brake or else you
will be brought back onto the track)

At Sears Point there is a hill with a huge Valvoline logo on it. Drive up the hill and you will fly into the air -- and your car may catch on fire. Go past the first hill at Sears Point (the one that if you go too fast you will ramp and hit the wall) to the Valvoline jump, but do not ramp it. Turn around and go to the left side of the screen next to the wall and accelerate. Go forward until you ramp (this jump can hurt your car more than the Valvoline jump). You can do 720s, nose dives, half flips, etc.

On the main screen, press UP, DOWN, LEFT, RIGHT, WHITE, UP, UP. NOTE: Press up on the D-pad to fire.
