To get
unlimited fuel, set your fuel level at 10%.
During
your game the fuel gauge will stay low throughout the whole
game.
Since there
is hardly any fuel in your car it can accelerate really fast.
TO GET
A FAST CAR:
Before
turning on the system, hold down the "A" and the "B"
buttons, hold until game tells you to press start button. At
this point, release A and B, then push down again and hold until
the game comes on.
