I’m looking for a retro video game server something like jellyfin but for video games. Is there anything like that? Something that could be played on remote computers or Roku/Android boxes? Something with clients? I did a cursory search but didn’t find anything recent.
Not sure about Roku, that might be asking too much, but Retroarch is the daddy of emulation frontends and I’ve seen people run that on Android boxes with ROMs just read from a NAS via SMB. It’s available on most platforms you can think of.
There’s also dedicated gaming OSes (which will run on many generic S905ish AndroidTV boxes as well as PCs etc) which serve as prettier wrappers to that and other emus, my personal preference being Batocera if you whole-heartedly wanting those client systems to become ‘retro gaming systems’.
KODI + IAGL would also be a workable soln on all platforms which have KODI, that can run the games directly from archive.org so negates need for the SMB share.
There’s also lots of retrogaming-adjunct subs where this will be answered better than by us nerds here too.
