One of the contributers for the ChimeraOS distribution got in touch with me yesterday and sent a link to his GitHub project: xPlayerOS. This is a couple of bash scripts to help those who have an Intel-based Onexplayer handheld get everything they need to get set up and running on Linux. The README mentions the script was specifically tested on Pop!_OS 21.10, but it should theoretically work across any Ubuntu-based distro, and maybe even Debian.
