There's also lemonade, which is prioritizing android compatibility but also looking to get desktop working at some point.
Lime3ds seemed a bit off-putting to me since the owner of the repo didn't actually have any experience with software/emulation development (I think they were a Linux/FOSS YouTuber), but idk how that has changed/if there are other people maintaining it now
I don't have any Citra successors installed yet because I still have my modded 3ds (I was only ever using it for specific game mods that don't work on native consoles).
That being said, I doubt It's still pretty early and developers have to get familiarized with a complex multi-thousand-line codebase they've never worked on before, so actual progress is going to be minimal.
