Instant Transmission Switch [Anarion]

NOTE: Only works consistently on Dolphin Emulator.

Works for both online and offline. You can change transmissions/drift-modes live in race.  The race/battle starts with a default state of being in Manual. So if you choose Auto and the race/battle starts, you will start off as Manual still until you hit your button activator/deactivator.

Key Remapper (Wii Chuck) [Bully]

Please note that unlike the GCN Key Remapper, this code doesn't swap button functions. For example, if you use the 1 Button as your Item Usage button, the original Item Usage Button (Z) is disabled instead of using the function of the 1 Button.

Please also note that the code ONLY effects live racing. Everything else, the control functions/keys remain the same.

Perfect Replace Item with Shared Item [Star]

This code will replace an item that you receive from the roulette, to a random legitimate one. It is undetectable.
