Here are some cheats and tips for the game Lemans 24H.
Sonic The Racer:
Before you press the ‘start’ button, step on the brake and never let
go. Choose a course. During the selection of the car, pull the
steering to the far left car (the “NISMO”-model) and press the ‘start’
and ‘zoom-in’ button together and step on the accelerator. Then only
you let go of the brake.
