Wii:CIOS Installation

Installing custom IOS is essential for using programs such as USB Loader GX to load games off of external storage. Some programs may also work better with custom IOS.

Warning: Although bricks are rare, they can still happen and this mod performs permanent changes to your Wii's NAND. With that in mind we recommend you perform a NAND backup if you haven't already. We here take no responsibility for damage that occurs to your Wii as a result of you following these instructions, you perform this at your own risk.

Notice: These instructions are not compatible with the Wii Mini. Do not perform these instructions on a Wii Mini as that will likely result in a brick.
