MiSTerFin
I have a MiSTer FPGA connected to a Sony CRT and installed the MiSTerFin project, which is a Jellyfin client for MiSTer. It's got a lot of things that need fixing, so I contributed a few PRs to fix some of the problems I encountered. MiSTerFin is written in C and I'm much savvier with Go these days, so I (and my helpful Codex prompt) forked it and ported it to Go (where appropriate). I've since been obsessed, making improvements, smoothing out rought edges, and adding features, all get a great Jellyfin player on my CRT. And I have to say, watching Robotech episodes on my 4:3 CRT from Jellyfin is a shot of nostalgia directly into my veins. I'll add a bit more polish and get it published this week for others that might be interested.
