Hidden Ending
To get a hidden ending in Mario Kart 64, place 4th place overall. This is a lot harder than it sounds because if you place 5th or
lower in any one race, you must restart. The easiest way to place 4th overall is just to get 4th place in every race.
Mario Kart 64 Secrets Don't slip!
If you slip on a banana, and are about to spin out, hit the brakes. You will stop (not spin out), a music note inside a balloon
will appear next to your driver, and you will have saved yourself a lot of time.
Booster
To get a boost at the start of the race and an early lead, do not hold the acceleration button before the race. Wait until after
the last light flashes, then punch the gas. If you time it just right, you should get a boost that puts you into first place
