I tried Syvalion and it seems ok for scoring and I didn't see any cheats online. I enabled it for high score, correct me if I'm wrong.
I looked up a couple others and found these-
Super off road has this one but I'm not sure if it matters compared to the actual long race.-
At the game menu press X, B, Y, A, X, B, Y, A. You will be able to play a race that is filled with money bags and nitros.It doesn't help you in the big race.
Btw this game is glitchy looking for me, is that normal? If so that sucks I used to love this game.
Gods has level cheats that starts you with money. Not sure if it's an advantage though.
