cIOS

{% include toc title="Table of Contents" %}

This tutorial will tell you how to install cIOS (custom IOS). This is required if you want to load games with a USB Loader. Some homebrew might work better using cIOS.

If you have a Wii U (vWii), follow this guide to install cIOS instead. Attempting to install any other cIOS on vWii won't work. {: .notice--info}

If you have a Wii mini, install this cIOS instead. Attempting to install any other cIOS on a Wii mini won't work. {: .notice--info}

What you need

• A Wii
• An SD card or USB drive
• d2x cIOS Installer

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 {: .notice--warning}
