How would reverse engineering c code be side loading? You can get .deb, .rpm etc and install them on your distro as long as it supports the format, regardless of who developed the app, and honestly even if it doesn’t support the format there are ways. You can even compile the source code of more Linux apps, at least the FOSS ones, with just a few commands. If anything it would be more realistic to say you can ONLY side load on Linux

I had this running on a raspberry pi, but it had constant crashing issues. I may give it another go with a mini pc

Yes! I’m saving now for a steam machine when it comes out too

I just wish there was a way to control the PC as easy as a tv remote. I would totally do this except my wife and kids just want to hit a button on the remote instead of fiddling with keyboard or a track pad or controller of some kind
