Where is code menu for ATV offroad fury pro?

First go to the main menu then go to options and then go to profile and in that section it says cheat.

here, this is the only code i could find so far type this in when you are there

Just type this in at the prompt to unlock all bonuses:

lazyboy: Unlocks all bonuses (cheat mode) so the code is lazyboy

i hope this helps =).
