Mario Kart 64

Get a head start: If you start in 3rd or lower position, continually press the jump button as the race starts. You should jump right over the other racers.

To stop a spinout when you hit a bannana: Just as you are about to spin out hit the brakes. If the timing is right your guy should whistle. (Note:Doesn't work in battle mode)

To access the three secret ghosts: You must win the following races with the listed times or better: Luigi Raceway : 1:51 Mario's Raceway : 1:29 Royal Raceway : 2:39 If you do any one of these you will get to race the programmers.

To do a power slide: While turning hold the R button then, wiggle the stick and your smoke will change colors. When it turns orange release R for a super boost.

To access the mirrored tracks: First you must get a gold in every race in the 150cc class. After you reset your machine, go into GP mode and you should have the new option under 150cc.

To get a speed boost: Right when the second light turns off, hit and hold the gas. If you timed it right you should get a good boost. If you hit it too soon, you will spin out instead.
