I thought you couldn't deactivate cheats...
the trainer ... lol... it's activated with F keys, and then you press it again to de-activate. I tried it before and got the firetruck in career mode I felt like doing pursuits with it... I rammed alot of em too.
And @ racing_nut, yeah he needs to be 13... should we report it?
I meant the normal code cheats, but I guess a trainer does alright too...
