Not to pile on, but to agree with the sibling comment: Dolphin (the GameCube and Wii emulator) is insanely good. It seems like Sunshine has weird issues but I've never had a negative experience with anything else and it works out of the box everywhere, even on Linux.
As a tangent just because of how impressed I was, I installed Dolphin on Linux via a Apt (I believe) and it just worked. I already had the GameCube USB adapter drivers installed and those just worked out of the box. I don't know how drivers work for selectively compiling with them from the kernel tree, but it appeared that they were part of the main kernel tree and they were just there for me.
