The installation is straightforward, but it requires a Wii with the already installed.
If you are modding a Wii in 2025, a good rule of thumb is:
: Once you see "IOS236 installation is complete!", press any button to return to the Homebrew Channel. When to Use Alternatives
(also known as IOS236 v5 or Simple IOS Patcher ) is a legacy homebrew application for the Nintendo Wii. Its sole purpose was to create a patched, custom version of IOS36 (Input/Output System) and install it as IOS236 . This custom IOS granted "Title ID" privileges, allowing other homebrew applications (specifically USB loaders like USB Loader GX and WiiFlow) to access the Wii's NAND memory and USB drives with full read/write permissions.
: Press A to begin. The installer will patch and install the files.
