cIOS

cIOS for Wii/Family Edition

Technical Details (optional)

cIOS (Custom IOS) are IOS that are patched to allow custom functionality. While cIOS has largely been supplanted by AHBPROT, which gives complete hardware access, it still has useful applications. For example, this enables the functionality of USB loaders like USB Loader GX and WiiFlow, alongside other pieces of homebrew like SaveGame Manager GX. You can skip this process if you want, but generally it extends your Wii with little to no downsides.

WARNING

Do not attempt to install a vWii/Wii mini IOS or System Menu on the Wii. Doing so will likely brick your console.

Requirements

• A Wii with the Homebrew Channel installed
• An SD card or USB drive
• The d2x cIOS Installer

WARNING

Ensure that if you are using an SD card, the lock switch is in the unlocked position, otherwise you will not be able to select the correct options in the installer.
