Crash Team Racing

You can't unlock Tawna in Crash Team Racing, although you can unlock Papu Papu, Ripper Roo, Pinstripe, Penta Penguin, Komodo Joe, N. Tropy, Fake Crash, and Oxide. (Only in PAL version for Oxide) Komodo Joe: Hold L1+R1, Down, Circle, Left, Left, Triangle, Right.

You can't unlock Tawna in Crash Team Racing, although you can unlock Papu Papu, Ripper Roo, Pinstripe, Penta Penguin, Komodo Joe, N. Tropy, Fake Crash, and Oxide. (Only in PAL version for Oxide) You can unlock any character besides Penta Penguin and Oxide without cheats. All of these codes have been tested by me (besides Oxide's because I have the North American version).

P.S. Always hold L1+R1 while entering codes!
You will hear a chime if it worked.

You may have noticed the words I posted under the codes. Like AXELWAX. These are the codes' code names. Down is D or S, Up is you or N, Left is L or W, Right is R or E, Triangle is A, Circle is O, X is X, and none of them have square.
