About

This all started out as a personal hobby project and it has exponentially grown into an awesome community which I am super thankful to have. It is built with simplicity in mind to play your favourite games with little effort. We hope this custom firmware brings you as much enjoyment as we’ve had developing it.

Features

One of the main features of muOS is how easy it is to get it set up and running. Just like other CFWs all you have to do is use your favourite image flash program to install it on your SD Card. Put the SD Card into your handheld, turn it on, and it will take care of the rest.
