Installing and Playing Mods

Mods are typically released as patches to the original game, for which you need the original disc. Most of them make use of an homebrew app named Riivolution, which patches the game files on the fly, allowing for mods to be run pretty easily. You can also find ready-made patched ISOs on the internet, which you can play with a backup loader or Dolphin, but this will not be covered here. If you are looking to test your own content on Riivolution or Dolphin, look respectively here and here.

Installing Riivolution
Riivolution requires the Wii to be able to run homebrew applications. A good guide for enabling homebrew can be found here. Note : the app only works with original game disc, burned ones won't work.

Download Riivolution from here and extract it on the SD Card.

Now place the mod of your choice on the SD Card as well.

Once done, put the SD Card on your Wii, open the Homebrew Channel, and from there start Riivolution.

If you are asked to install IOS 37, let it do, but NOT if you are on Wii U, or you will brick vWii.

The program will then load. Feel free to press Install to add a Riivolution channel to the Wii Menu.

Enable the mod of your choice, then select Load, and the game will start.
