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. 如果你想使用USB Loader加载游戏，你就需要这个。 有一些自制软件使用cIOS会运作的更好。

If you have a Wii U (vWii), follow [this guide](https://wiiu.hacks.guide/#/vwii-modding) to install cIOS instead. Attempting to install any other cIOS on vWii won't work.

Although the majority of games should work straight away with the defaults, some may require using a specific cIOS to function, or to utilize certain features within the game.<br> Examples include:
