For access to the secret cars, hold C-Up + C-Left + C-Down at the car selection screen.
To access three tracks that you normally can not race without "Crusin' the USA", go to the track selection screen and hold the proper buttons:
| Golden Gate Park | L + C-Left + C-Down |
| San Francisco | L + C-Right + C-Down |
| Indiana | L + C-Right + C-Up |
Flashing Lights and Siren:
Start a new race as the School Bus or Police Car. While playing, tap Brake, Brake, Gas to flash your lights and/or sound your siren.
Enable the "Secret Head" code, then start a new race. While driving, press Brake, Brake, Brake, Gas, Brake, Gas after each checkpoint for a nitro boost. This won't increase your top speed, but it will increase your acceleration.
To view the secret head, make a "Hot Time" on any stage. Enter your initials and scroll down to the bottom of the screen, then hold Left on the analog stick for about 35 sec. A head should come moving down the conveyer belt saying "I love this job."
While driving, pump the gas twice and you will do a wheelie and it will give you a turbo boost.
After a two-player challenge game, the losing player's right front wheel will fall off if you continuously rotate the analog joystick clockwise. This should happen after the car rotates 3-4 times. Talk about driving till the wheels fall off!
Here's a faster way to update cars in a two-player game. Start a two-player game, and race until you reach Washington D.C. When the DC race begins, press Start and quit the game. Next, have player #1 return to Washington D.C. and upgrade his car. After player #1 has finished, player #2 should do the same thing. Happy cruising!
