You don’t even need a Switch to play Switch games, just a somewhat decent PC. Keep it on the down low though, Nintendo doesn’t like it and they have an army of fanboys who will defend them.
You only need a physical Switch and to dump the games if you want to do everything perfectly legally.
I hopped around until I found Arch, and it has been rock solid, first time an OS has lasted ten years without needing a reinstall. Windows has never lasted more than two years without shitting itself.
