Test Drive 5
Electronic Arts
Go to the first options screen and type these high speed, high thrill factor codes:
cup of choice	Unlocks all tournament races
that takes me back	Enables backwards mode
i have the key	Unlocks all cars and tracks
Other cheat codes:
These cheats won't work unless you have an entry on the high score screen, so make sure you have the checkpoints turned on (you can do this from the options menu).
Knacked	Reverse tracks
whoooosh	Nitros (press the horn button to activate)
mjcim.rc	Remote control cars
sausage	Bonus cars
NB: After entering the codes make sure you save your game, otherwise you have to go through the entire cheat process again next time you load it. Also, watch out when using the nitro code - you'll spin out unless in second gear or higher.
