Things You'll Need
Instructions
Download the NeoGamma files to your desktop. (See the link in the Resources section.) This folder contains the necessary files for this tutorial. When it downloads, right click and unzip the downloaded folder to the desktop.
Insert the SD card into your computer, and open it to see its contents. Copy the "apps" and "NeoGamma" folders that you downloaded onto the root of the SD card. If a pop-up says the "apps" folder already exists, click "yes" to merge the folders.
Open the "wad" folder on the root of the SD card. If there isn't one, create a new folder and name it "wad." Copy into this folder the "Neogamma R9B37 - NG37.wad" you downloaded. Close all the folders, and eject the SD card from your computer.
Insert the SD card into the Wii and run the Wad Manager. (If you have the Homebrew Channel, you have the Wad Manager). Choose the "Neogamma R9B37 - NG37.wad," and install it.
Reboot your Wii. You will see the NeoGamma Disc Channel on your opening Wii Menu. Insert your backup disc, run NeoGamma and select "Launch Disc."
