These codes are all really ! Lol, here's another one:

Name of Fake Code: Yoshi Turns Pink
How To Do It: Play as Yoshi on Mario GP with only 1P and with Mirror ON, then do the cup with Yoshi's Valley. Make sure you come in 1st place on the race before Yoshi's Valley. When you get to Yoshi's Valley, fall into the ditch 3 times, each time taking a different route then the next. As soon as you fall off the 3rd time, the game will Reset and Yoshi will be Pink! To keep Yoshi Pink, do Bowser's Castle as her, to change Yoshi back to green, do Wario's Stadium.

Mod edit - cleared up details

Name of Fake Code: How To Make The Graphics Look Like The SNES Graphics And Play As Whomp-Block.
Description: Go to Bowser's Castle as Princess Peach on Time Trial. Finish 1 lap, but on the second lap, stop when you get to Whomp-Block in the jail cell. Slowly ride forward to him and he will say something; "Please, free me from this awful place! In order to free me, you must defeat the ghost of yourself. Finish this round, and then do the next round, make sure you beat your ghost!" Peach will say, "Well, I'll try...". Finish the lap and do Bowser's Castle again, make sure you get to the finish before Peach's ghost. If you beat the ghost, go back to Bowser's Castle. There will be a key lying on the floor in front of the jail cell, push it to the cell, and the cell's bars will open up. Whomp-Block is free! But, he stomps so hard when he walks, he made the graphics look a little distorted so that now, it looks like you're in a SNES (Super Nintendo).

To get Link and Diddy Kony in the game you must beat the game and get Extra 55 times.

Play this game for the rest of your *bleep*ing life and u get SUPER MAN IT EZ

Uh oh, the blue blur has come to play!? Hooo boy. Here's how to do it.

1. Win all the Cups and Mirror Mode 64 times over, using each character.
2. Use Mario and get past each of the courses in less than 1:30 for the Mushroom Cup circuit, 1:20 for the Flower Cup circuit, 1:10 for the Star Cup circuit, and 0:59 for the Special Cup circuit.
3. Reset.
4. Before the Nintendo sign appears, press A, B, B, A, B, B, L, R.
5. When you select your character, Sonic should be there. Time for the BLue Blur to burn rubber of the NInetendo competition...

Oooh, this gonna be a doozy.

1. Mini-Turbo at every turn using Mario in the Mushroom Cup, Luigi in the Flower Cup, Toad in the Star Cup, and Yoshi in the Special Cup. Do the same thing for Peach, but this time, Mini-Turbo on every turn in EVERY course, and finish each course under 2:00.
2. Reset, press, A, B, L, A, R, and Start before the Nintendo logo pops up, and when you select your player, Jeff Gordon should be there. *in a deep voice* Awaken, Rainbow Warrior... *deep, evil laughter*

Make all the characters die except you:

Go to Rainbow World, and use the lighting bolt when you are trying to get the shortcut. If you get everybody, the course will fry and everyone will fall off. If you fall off, Latiku will put you on the other side, while the opponents die at the course.

To play as penguin:

Play the snow course with the penguins and put a banana peel in the penguins path. The Penguin will follow you. There will be 9 racers now. If the penguin finishes 3rd, you get the penguin and replaces the character in last.

Play as Diddy Kong:

Play at Donkey Kong's course with Donkey Kong and get hit with 15 coconuts. Diddy Kong will feel sorry and take Donkey Kong's place. You have Diddy Kong now instead of Donkey Kong.
