While [cIOS](https://wiibrew.org/wiki/Custom_IOS) has largely been supplanted by AHBPROT, which gives complete hardware access, it still has useful applications. For example, this enables the functionality of USB loaders like USB Loader GX and WiiFlow, alongside other pieces of homebrew like SaveGame Manager GX. You can skip this process if you want, but generally it extends your Wii with little to no downsides.
This d2x cIOS installer was originally developed for the Wii U's vWii by DaveBaol and custom cIOS was created by Leseratte for the Wii mini. The original download page can be found [here](https://wii.leseratte10.de/d2xl-cIOS/). Leseratte's GitHub page can be found [here](https://github.com/Leseratte10/d2xl-cios). Please note that this cIOS is still experimental, though no problem with functionality has been reported.
+ If the install fails with a `TMD version mismatch` error, press left or right on the +Control Pad over the `Select cIOS base` option until the version number is different than the one you tried before. The number 57 will not change.
If you wish to use Wiimmfi with Ethernet on a Wii mini, you have to run the [Ethernet Enabler Homebrew](/assets/files/Wii_Mini_Ethernet_Enable.zip) app made by Fullmetal5. To run it, just unzip it in the `apps` folder of your USB drive and run it from the Homebrew Channel.
The Wii and Wii mini consoles are only known to work with Ethernet adapters using the AX88772 chip. Please check that the product is compatible before you buy. This one from UGREEN is known to be compatible: [Amazon Europe](https://www.amazon.de/dp/B00MYT481C), [Amazon US](https://a.co/d/3OcSJDS)
