Unlock all cars
1. On the 4 Wheel Thunder 'Press Start' screen (before the Main Menu), hold down the Left Trigger + X together, then press Start.
If you do not have a VMU on your controller, a warning message will pop up after pressing Start. Select the 'Continue without saving' option by pressing A.
2. On the Main Menu screen, place the cursor on 'Option', hold down X and then press А. IMPORTANT: If you get a loading screen instead of the Main Menu, the cheat will not work. Once that loading screen ends and you get to the Main Menu, you will need to soft reset your Dreamcast back to the 4 Wheel Thunder 'Press Start' screen and start again.
3. In the Option menu hold down Y and then press В. A 'jackpot sound' should occur if you have done this right.
You will now be able to use all secret cars & customizations in this game, including the CPU cars (under the 'Bonus' names). However this cheat will not unlock the Special Midway car; that has a separate code.
Please note, this cheat does not work in Championship mode. This cheat is also the only way you can play as the CPU vehicles however be warned as they are quite underpowered.
