F1-Roc (SNES Cheats)
Hidden Course
Choose 'Start' on the title screen. Get past the player select screen and choose 'Training' in the Config screen. When the course screen comes up, highlight and choose the MONACO course. Do all of the changes you want to your car and start the race. While you are racing, look carefully for a body of water that comes to a point between two gray barriers. Once you find this, get up to top speed (turn around and come back if necessary) and head for the water. If you place your car just right, you will be able to run your car on the water without falling in. Search for a significant opening from the water to green grass. Once you get to this, you will see that it leads to a new course that is not even on the map.
