You'll find this shortcut in Waluigi Stadium. When you get to the part where the giant wooden pirahna plants are. Start drifting when you get to the last pirahna (making sure you build up a mini turbo.) Release and go up the hill thingy. (Carefull not to crash into the gaurd rail, and jump to low.) When your kart takes flight. You'll go toward the ramp. If you do it right. You'll see that your thrower, yell like a baby. If done right' you will see that lakitu takes you to the front of the ramp. All you have to do is continue racing.

P.S. Takes lots of practice

Press L, R, Y, A at the main screen(title screen)

When you begin there will be the item boxes (note: if you do not get a mushroom this will not work)Make sure you get one of the item boxes, and if it's a mushroom by the time that you get to the fallen pillers by the catus monster things use a mushroom right before you get on the sand, you will jump over to the other side...its just easier than turning, lol, bye

You can get an easy mushroom by a shell( red or green).When you see a red car with white dots and shaped like a mushroom, hit it with a shell. It will pop out a mushroom. This way is more convenient than bumping your Kart into the car and slower your speed, and you can even get a mushroom by using a green shell when you're in 1st place.

Bowser first then King boo on boo pipes or parde kart. Or King boo first with mario.

Beating the staff ghosts doesn't earn you anything, but it does give you something to brag about. If you beat the time, you will unlock the staff ghost. After the time is the driver/passenger "kart". I don't know the times it takes them to go around the track.

If you want to be stable and not fall of the bridge on the donkey kong level near the finish post do this.If you are falling to the right of the bridge click the L button and if you fall to the left click the R button. Good Luck!!!!!

Mini boost: On any turn, drift (hold L or R while turning) now, using the control stick, and still holding L or R, go left to right the sparks turn red.
Now go left right again the sparks turn blue.
Release L or R. youl get a small but fast speed boost....

Beat all cup tour on 150cc.

Hello. I am marthman. I am new to this so this is my first cheat.
On any turn if you hold L and R trn left/right while wigling the control stick left and right. Do that and then red sparks shoul come up then blue sparks come up. Let go and you get a small booost it works trust ME

Ok now this isn't the best cheat in the world or anything but it's pretty neat.On the level Peach Beach when you first get started keep going until the first turn,but do NOT go right!Turn left and you should see a green pipe.Go inside of it and you should get shot out and you will get a double box.
(NOTE)There are only four of these in the whole level so....START YOUR ENGINES!

To get a boost at the start of the race tap the A button when the 3 2 1 is counting down.

To get better times in time trial mode use mini boosts ALL THE TIME!

Go to 1p mode, then pick time trials, then pick whoever you want to on any cart. Pick Sherbert Land (Star Cup) then go backward. Turn around. Go to the giant ice things and right when you are about to hit it switch (Z button). When you get unfrozen you should notice that on the map something is not right.(Lets say you were Mario and Luigi. Mario is on the back but on the map it says Luigi is on the back. To get them both on the back press Y or X. DONT SWITCH. You can still drive around but don't get hit by anything. YOU DONT HAVE TO DO TIME TRIALS OR 1P MODE. IT IS JUST THAT THERE IS A LESS LIKELY CHANCE THAT YOU WILL GET HIT
Have fun with this cheat.

Beat the game. Then delete the game. Then do that cycle 5 more times. Then once you have paratroopas kart, complete the time trial for mushroom city. Beat every ghost including the expert staff. Once you do that. Go to the characyer selection and if you hover over koopa, press Z and it will turn into hammer bro. Paratroopa will turn into fire bro
