Go to the 'Select Number of Players' Menu. Highlight 'one player'. Take out all of your fingers. Hold down L1, R1, Start, Right, S, and T. Now press X. (If you have no fingers left, use your nose).
Now there's a new track called Firestar! Go racing on mars!
Want to try out the Rapier class without all that pesky racing? Go to the 'Select Number of Players' Menu. Highlight 'one player'. Flex all of your fingers, crack your knuckles. Hold down L2, R2, Start, Select, and Left. Now press X (or ask a friend to).
