spruceOS
-
SpruceOS is a community software package intended to help you get the most out of your Miyoo, TrimUI and Anbernic RG XX devices.
-
Our mission is to provide a balanced user experience for both brand new and well-seasoned emulation enthusiasts alike: sane and well-optimized defaults for those who don’t want to tweak settings, but immensely deep customization options for those that do.
-
Spruce is intended to be sleek, intuitive, efficient, and user friendly. We hope that you enjoy it.
We are not responsible for damage to your device. You must use spruce and its features at your own risk.

- We are always seeking new themes, and would love to feature your artwork! If you are interested in contributing a theme, please reach out! There has also been some preliminary work on a Theme Guide to help get you started.
