For any of these cheats to work, you must first have either beat the tournament twice (one time just gives you the extra track) or have patched the game. When this is done you must type the codes (complete with spaces and in ALL CAPS) where your name goes:
The Need For Speed
EAC POWR: Gives you the "Warrior" car, an 800bhp car, capable of over 260mph.
EAC RALY Changes the track that you are on, try it and see...
EAC WARP Makes the game faster by improving the handling of cars and making the enemy better.
EAC 4X4R Removes all the 4X4's, trucks, and vans and replaces them with cars.
NOTE: If you wish you can combine the codes, i.e. for the code you could put in EAC RALY POWR.
