There is a hidden MASTER MODE that enables a player in a single mode to play against not just on boss but all bosses.
In VERSUS MODE, players can turn off the handicap mode. This is the mode that keeps those races neck and neck. All players must select a course using the secret command of pressing the VIEW CHANGE BUTTON with the ACCELERATOR fully open and brake lever pulled back fully. A star will appear at the lower right corner of the race screen.
