Patreon about page begins: >yuzu is a Nintendo Switch emulator capable of running many games! With yuzu, you can play such games as Pokémon Sword & Shield, Xenoblade Chronicles 3, Super Mario Odyssey, Mario Kart 8 Deluxe, Pokémon Legends: Arceus, Fire Emblem:Three Houses, and Super Smash Bros. Ultimate — on your PC. Regardless of the legal status of an emulator, I wouldn't list game titles if I were writing that copy…
It's not illegal to play games that you already purchased and own. Piracy is just a convenient scapegoat to hobble emulation.
Zelda BoTW being released 7 days BEFORE being on Switch, and 60FPS, and better gameplay on a real computer is what caught Nintendo's attention.
And with Yuzu and joycons, you can have EVERY game, including their online only stuff. And if you pay for those online only, piracy is the only way to guarantee that you'll keep them.
They've destroyed the: NDS, Gamecube, Wii, WiiU stores/online content. They never needed to. They *chose* to.
