If you’re interesting in gaming and multimedia, one choice is to run Linux based RetrOrangePi or RetroPie on your favorite development board/SBC, and soon, with the upcoming release of Kodi 18, multimedia and retro gaming will just be an app installation away in Android, and other supported operating systems, since RetroPlayer retro-gaming emulator is part of the latest – and yet-to-be-released – version of Kodi.
The description claims that Stations OS includes “more than 20 kinds of optimization for video and games, achieve multimedia center, Kodi 4K hardware decoding, game simulator hardware acceleration, real-time cast screen display, network acceleration, perfect Root.”
The firmware does not use Kodi directly, but RKMC fork instead with some improvements, and they call the game emulator “Game Station”. The company has release “Station OS Community Edition” for a while, and the latest release is version 8.0 at the time of writing. It’s free to use, but not open source, so it will probably only ever work on T-Firefly boards with a Rockchip processor.
