I’ve been using Arch for a year and nothing has broken. Did have to “fix” a lot of stuff after install because it was my first time using Arch and didn’t realize all the other stuff I had to install… Mainly to get my Nvidia GPU to work. But a few hours later and it’s been rock solid since.
I used emu deck and it made emulators too easy to setup. Never did the switch stuff but have ran cemu for breath of the wild for wii u. Also have the original Xbox emulator and GameCube going.
