Oh, I installed Ludo (the program, not the LibreELEC based LudoOS) on my Debian laptop a couple days ago. I don't have the time, knowledge or patience to fiddle and try to optimize Retroarch. For Android, I use Lemuroid, which has a similar premise of simplicity.

Back on topic, there's also Lakka as a LibreELEC with full Retroarch. I think there are other similar projects around, like EmulationStation.

Ugh. I really tried to like Lakka but it was such a mess. I'll never install a non-raspbian OS on a rasppi again.

I like the naked Retroarch UI so much better than emulation station so I thought that part was much better than retropie, but the amount of fiddling I had to do with the OS on a system that really didn't want me to do that ruined it for me.

Yet more evidence that XMB is the greatest console UI ever created, and I'm glad more projects are using it in some way.
