Episode I Racer Cheats & Tips

On any of the Ando Prime Snow levels, do one lap as usual. Then, when you come up to the starting line, veer off to the left and and you should see that one of the tents is open. If you manage to go through the shortcut unscathed, you should be comfortably ahead of everyone else. You can repeat this on lap three also.

Beat Galactic circuit an Sebulba will be on the racer select screen.
OR
Beat the first race in first place twice

DO NOT finish the Boonta Classic unless you are in first place. If you are in a different place you obviously won't get the favorite (Sebulba), and you will have to sit through the un-bypassable ten-minute credits. So if you want Sebulba quit before you are finished if you are not in first. It's a real time-saver!

On the screen you see after you choose a place to race in, go to buy parts. Select one of the items and hold Shift+F4+4. You should receive $1000.

When you are in the place you buy parts, get to what you want and then(in this order)press "Ctrl"-"F4"-"4". note it looks like the other code but is not. So make sure you press Ctrl instead of Shift.

Right before you go into the race, press spacebar when start race is selected.

On any Oovo IV level just before exiting an anti-gravity tunnel pull up and keep pulling up away from the ground and if done right, after exiting you will keep floating in the air hugging the ceiling.
