Alternate soundtrack:
Hold Start when the message "Gentlemen, Start Your Engines" appears prior to a race. Release the buttons when the phrase "The race is approaching" is heard.
Turbo boost:
This code will only work if you see your car or the demo of this game with a big wheel instead of a small wheel (which is the default one). Hold Start button while racing to execute a turbo boost. Your speed will increase as long as you hold this button. However, do not hold this button too long or you will lose control or collide with the other racers. Use this at your own risk. Another way to find out if a particular machine has this feature is that the "Insert Coin" message is replaced with "Press Start for Turbo" flashing in the screen.
