Too lazy to go through the game and unlock everything the way you're supposed to? Ugh, I don't know why I'm helping you.

The passwords must be entered exactly as shown.

I have tested all of these myself, and they are typo-free.

If you have a Maxdrive and either the AR Max or the Maxdrive disc, I've uploaded a Maxdrive save to GameFAQs that has everything unlocked. Enjoy.

Just in case you didn't know, the password entry screen is under Game Options. Select Load and Save, and press right/left to change the option from Memory Card (PS2) to Password. Press X and you'll get the password entry screen.

Thanks to jslbmiller (at) bellsouth (dot) net for bringing this to my attention.

One last note before the passwords: Each cup password unlocks everything that all the codes before it unlock. So to unlock all the tracks and championships, you only need to enter the last cup code. You'll still need to enter the codes for the easter egg cars, though.

Enter this password...	...to unlock...
