GoKawiilWine-NX homebrew brings Windows PC games like NFS Underground 2 to Switch
A homebrew project called Wine-NX ports Wine 11 to the Switch's Horizon OS, letting it run x86 Windows games via Box64's ARM64 translation and Mesa's nouveau graphics driver. Demonstrations show Need for Speed Underground 2 playing at 20-45fps, OpenTTD hitting 60fps, Quake III Arena running around 37fps at 720p, and WarCraft III partially functional with menus and cutscenes working.
