To my knowledge, it's that the analogue devices are running the game in real hardware and not emulation, even if you run the files off a flash cart.

That's not worth it for many people, but if there's some game that you can feel isn't quite right on emulators, there's a good chance the analogue can be the closest to the original experience. It's definitely niche and priced accordingly.

Woah now, what's this KVM adapter now?? That sounds incredible

I hear this opinion a lot, and I'd just like to add it manages to help with some exposure and repetition at the very least. I'm sure you're more knowledgeable than myself with learning languages, but I've been using Duolingo to learn Japanese for a little while now and have managed to pick out basic hiragana and katakana here and piece together small words.

I don't have any delusions that I'll be fluent if I finish this course, but if it can help me learn the characters it's worth the time to me.

Oooh I might have to play around with it some more then. I have it running alongside Plex but haven't used it in a bit

I have to admit, I really love the skip into feature on Plex. The fact that it runs locally and just analyzes audio for it is super cool for me.

It's above my knowledge to do it myself, but I'd love to see that implemented in jellyfin eventually.
