About MustardOS
MustardOS, also known as muOS, is a custom firmware primarily for handheld gaming devices such as Anbernic handhelds. It replaces the stock system with one that emphasises configuration and theming, so owners can change the look, style and behaviour of their device.
The project started as a personal hobby and grew into a community project with its own Discord, forum and IRC. Releases are published on the project site with a numbered history, and the site asks users to download only from its official page or supported mirrors.
