SX Superstar Cheats - Xbox

Get a new girlfriend
To get a new girlfriend, win three races in championship mode.

Bigger air
To get bigger air, hold [L] as you go up the ramp. Release [L] (ideally when the gauge is full) at the lip of the ramp.

Quick start
During the countdown at the beginning of a race, do not hold [A]. Instead, press [A] as "Go!" appears, and you will launch off the starting line.

Realistic back flip
Since the back flip trick goes very fast and looks unrealistic, there is another and much better looking way to do one. Use the "Bigger air" trick. After you launch off the ramp, hold [Back] and you will do a better looking and more realistic back flip. You can also do a front flip like this, but it requires some skill, and big air.

360
Press [Down/Right] after getting a lot of air.
