After Yuzu got shut down I'm not sure what this leaves people with for switch emulators. I'm going to try and find archives and will update the post when I do.
Last windows build: archive.org
Slightly older, but has linux and mac builds archive.org
Okay there we go, a github mirror: https://git.naxdy.org/Mirror/Ryujinx
The code of the last version must be available to find, it probably runs most of the games. Yuzu and Riujinx legacy must be continued, but on other places, not corporate controlled ones (Both countries and platforms).
