Alternate music
After completing the game, go on to Mr. X's track. When the race starts, press [Esc] to quit. Then, go on to either single player or multi-player mode. The introduction will appear and will give the track Mr. X's music. It only lasts for that race. This must be repeated if you want to hear it again.
Very high jumps
Fall when you get off the jump at this location. Most of the time you will jump very high (greater than when you are shot from a cannon). However, you may just fall. However if you jump, you can reach the other side of the building area.
