To play the game with a bike from Super Hang-On instead of a Formula 1, first select World Championship => New Game => Master Mode. In the "Name Entry" screen, input "HANG-ON!" at the "Name" section, then select "Ed". A screen of Ayrton Senna talking to you will now appear: at that moment, press the Reset button of your console. Go back to the main screen, and now select "Free Practice". Select your race track normally; then, on the next two selections (Image Training/Free Run, and Grid/Laps), choose your settings, and validate each of them by pressing and holding the buttons Down + A together until the next selection appears (on the Image Training/Free Run selection, make sure to press up or down once, before pressing and holding Down + A, so you validate the code on "Image Training": the Hang-On mode is only playable in Image Training Mode). After this, you'll enter the Transmission Selection screen: select your transmission normally. If the inputs were done correctly, you'll now play with a Super Hang-On bike.
