Hint: Winning in master mode:
Upgrading the ship is crucial to finishing this game. The basic premise is to have the racer's ultimate weapon by the end of your first master race. Follow any course you can, but that weapon is crucial to winning the races ahead. The premise is this. Race smart, but not hard. Stay in the back of the pack building up your weapons. You have five laps to eliminate five people. On the tracks such as Fuusoka City, where they all bunch up in the turns, it is possible to remove every other racer by the third lap.
