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
Fuck. This is a sad day for gaming. Kicking myself for not keeping my local clone of the repository up-to-date, but as you say I'm sure it's out there.
The emulation scene is really going to have to figure out a reliable and reproducible way to work on these projects while keeping out of reach of Nintendo's lawyers, since it doesn't seem like the whack-a-mole is ever going to stop.
