Warning: This is the old version of this page kept for posterity. It is no longer maintained. The new method is easier to understand and less prone to error. The new method can be found here.

IOS236 is a patched version of IOS36 that makes installation of other IOSes easy, even if the other IOS slots are filled by stubs already. See the IOSes Explained page for more info.

What you should install first

Information Needed

The method you use to install IOS236 depends on your installed firmware version. You can find your firmware version on the Settings page of your Wii accessible from the icon at the bottom left of the Wii Menu. The version will appear at the top right and will look something like 4.1U where the number is your firmware version and the letter is your region. Click the appropriate option to see the steps for whichever method suits you.

My Wii is at firmware 4.3

My Wii is at firmware 4.2 or less
