Can you add in the trainer a way to stop the damned clock for the races!!! The first race in Subway Town has me going off a ramp that's at any angle and in the 26 times I've tried it, I've always ended up on the freaking mountain! There's absolutely no way anyone can make the 1:40:00 Time Limit when stuck on a mountain.
Have you tried using an hex editor to just freeze the values yourself?
