Star Wars Episode I: Racer (Nintendo 64)

Star Wars Episode I: Racer is... a Star Wars-based racing game. Yeah.

Debug mode
Start up a new game file. At the name entry dialog, hold the Z button and type in the code RRTANGENTABACUS using the L button. While still holding Z, press End with L and if you typed in the code correctly, you'll get an OK and the name will be blanked. Now, enter any name and start a race.

During the race, pause the game, and rotate the D-Pad counter-clockwise. This will open up a neat set of debug options, under the guise of a fourth menu item: "Game Cheats". This menu is navigated by using the joystick or C-buttons to scroll between items and the D-Pad to switch between settings. The D-Pad must be pressed for every increment change.

Debug Level - 0 by default. Values range from 0 to 6. For 2 and above, two variables labeled "COMP" and "POS" appear in the lower-right corner of the screen.

Invincibility - Off by default. Toggles between on and off.

AI Level X10 - 8.64 by default. Left and right change increments by 0.01. Up and down change increments by 0.10.

AI Spread - 20.00 by default. Left and right change increments by 0.50. Up and down change increments by 5.00. Values range from 2.00 to 200.00.

Death SpeedMin - 325.00 by default. Left and right change increments by 1.00. Up and down change increments by 10.00. Values range from 20.00 to 1000.00.

Edit Vehicle Stats
Brings up another menu which presumably allows you to change various statistics for each racer. Highlighting "Name" and using the C-buttons or D-pad allows the player to edit other racers.
