To enable cheat mode in this game, you have to go to the main menu and then select “Game Modes”. After that, choose the "Fight To The Top" mode. Since then you can enter one of the following codes (note that they are case-sensitive). These codes consist of the first and last names at the driver information. With their help you will activate one of the effects you see in the list below!
Get Old Spice Fantasy track + all cars and drivers. The first name must be "KeepCool" and the last one is "SmellGreat". Thus you will unlock the above mentioned track and cars and drivers in all divisions (they are four, by the way).
Unlock Wal-Mart track + cars. The first name must be "Walmart". As for the last one, use "EveryDay". This cheat will help you get the Wal-Mart track in Race Now mode, Wal-Mart sponsored cars for all racing series and Wal-Mart sponsor for Create-A-Car mode.
How to get $10,000,000. Actually, you have to enter "GiveMe" as the first name and "More" as the last one. However, that’s not all you can get! So, if you want to get more, type "GiveMe More" as a name, then you have to select the “Edit” option to go back to the name entry screen. Accept this name one more time to get another $10 million easily and quickly!
How to unlock No Collision Mode. All you have to do is to use "Walmart" as the first name and "NoCollision" as the last name. While in the Damage selection, it’s possible to toggle this option. Note that when the option is on you can drive through other cars with no damage. At the same time, your Rival meter will be on lower position. What a pity!
