Micro Machines Cheats

Find the three hidden stars located in Graveyard GP in single player mode. They are located behind a rock just before the bridge with the skeleton of the man with the weird glasses; destroy the sail on the coffin path next to the sign "Bob Fat and Bald 1802 - 1852"; and in a secret shortcut located right of the fast forward power-up after the man in the jail cell.

You can unlock bonuses through the game by finding three stars in each GP level in single player mode

Find the three hidden stars located in Beachside GP in single player mode. They are located to the left outside of the submarine helmet; behind the sand castle before the beach ball; and underneath the first jump at the very beginning.
