cheat for gp1??

I want to unlock all the good bikes for Moto GP1 so it will
save for xbox live.

I have used the code for unlockng all the bikes in the full version but it doesn't seem to save your info.

I got this game on rent, so I just want to quickly unlock everything and play the live version on the demo disk..

Is there any way I can cheat and do this quickly??

playing the game through and unlocking them is usually more gratifying and will increase your skill.

but if you really want to cheat, check gamefaqs.com, they would have it if its available

Cheats will NOT work for the online gameplay for motogp 1. You can however use them on the offline portion of the game all you want. They just do not transfer to the online portion. You must earn that the old fashioned way.
