openmw VS inevitable-brew

That last one is an open source engine for a trio of existing free games, but if we count open source engines for commercial games the amount of famous examples grows exponentially. All id Software games up to Doom 3 have had their engines made open source and have a huge number of modern versions available for all of them. So Arcane Dimensions, the greatest by a mile Quake campaign ever made, was completed just three years ago and you need a modern open source engine like vkQuake to play it - even the Quake Remastered engine can't handle the huge AD maps. There's also an open source Morrowind engine, an open source Freespace 1/2 engine (Diaspora above actually runs on this), an open source point and click engine called ScummVM that runs so many old adventure games it's almost an emulator...

OpenMW is a clean-room implementation of Morrowind that is far more stable. I'd recommend using that instead of the original game engine.

OpenMW's official builds are for Windows, Linux and Mac so it shouldn't be that hard to get it running on one of the retro gaming linux distros I suppose. We have one guy that was working on getting it to run smoothly on Batocera with his RG351P, but I think he stopped working on it after a while. If you can help out, let us know! Go to www.openmw.org and you'll find our forums and our discord/irc/matrix channels.

You don't need to put android on the switch to run openmw. There's an unofficial homebrew port. https://github.com/fgsfdsfgs/openmw

Try www.openmw.org maybe?
