Mario Kart 64

Get the gold trophy in the Special Cup 150cc in Mario GP. You will see the credits roll. After that you will be able to access "Extra" mode in Mario GP, which allows you to play the courses as if they were mirrored.NOTE: You can't use "Extra" for Battle or Time Trails.

I have 2 cheats for you!

1: this can with any character: if you're racing, hold ''R'' by a turn. if the turn is left, push your yoystick for a second to the right. do this two times, and you got a short turbo! this works also by a right turn.
2. if you play VS with 2-4 players, AND you got a long way head to the other players, stop your kart in the final lap close by the finish, spin around 180 degrees, go backward and you hear 2 finishes for you. you see then 2 points in one race!

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!

Enter time trial mode and complete a course, beating the time indicated below. Then, select "Retry" to race the course again. The phrase "Now Meet the Course Ghost" will appear. The course ghosts are automatically saved to the cartridge for future replay without beating the course time again.

To get these ghosts, you must beat the times listed below.

Luigi Raceway 1'52''00
Mario Raceway 1'30''00
Royal Raceway 2'40''00

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.

Get hit by someone with star at Choco Mountain. While you are in the air. hit the side of a boulder. The game will not be sure if you hit it, and makes your character get flattened, then back to normal, and back to flattened again, etc. until you hit the ground.

Go to Choco Mountain and get up to the part where the boulders are located. Try to land underneath the shadow of the boulder on the small sloped hill next to the lake. If done correctly, you will get picked up and hit the boulder from underneath then get half flattened and half stretched. You will go back to a normal shape when you land back on track. This requires precise timing.

If a CPU character slips on a banana into abyss, the game thinks there on the "ground" and they will "drive" in the air. Note: If you see them, they will enter the "Trapped CPU glitch".

As Yoshi, go to a location where the spiky balls will shoot at you. While they are shooting at you, hold B. It will seem like the spiky balls are crying, and they will bounce off you instead of hitting you; as a type of shield. They will start to pull you closer to the wall. When you get to the wall and the balls shoot at you, it makes a loud hammer sound. You will never get pushed back unless you stop holding B.
