Pace car:
Hold Start + Brake while choosing a transmission at the selection screen. Keep both held until game play begins.

All cheats:
Insert your coin(s). Hold Brake + Zoom In + Zoom Out and press Start when choosing a transmission and track at the selection screens. Keep them held until game play begins. If done correctly, the race will begin with the pace car, on a backwards, mirrored track with no CPU cars.

Reversed track:
Hold Zoom In + Zoom Out while choosing a track at the selection screen. Note: This may only be enabled in a one player game.

Panoramic view:
Press Zoom In + Zoom Out while the view is zoomed out.

Police car run:
Hold Start + View + Brake + Accelerate while choosing a transmission at the selection screen. After selecting a transmission, press Start + View + Brake + Accelerate. If done correctly, a police car will run around the track in the opposite direction.

Glitch: Fast first gear:
Begin game play with a manual transmission. Enter the pits while in sixth gear. If done correctly, the game will shift your car into first gear and allow you to drive over 200 mph without shifting out of first.
