From the video's description, the emulator being used is called Ryujinx, though Wccftech reports that another emulator named Yuzu can run Skyward Sword HD as well. The YouTube video below is by NoBigDeal La, and it shows Skyward Sword HD-which was released for Nintendo Switch on July 16th-being emulated with twice the resolution that would be available when played normally.

However, seeing Link return to Skyloft on PC, hackers have already found out how to successfully get Switch emulation functioning. Since that time, WiiU emulation took some years to master, and one would expect that the modernity of the Switch would make perfecting its emulation take even longer. But even Dolphin eventually came to support upscaling Wii games to higher resolutions and increasing their framerate. The original Skyward Sword launched on the Wii in 2011, and players figured out how to run the game on PC using the emulator Dolphin. Compared to the native 1080p 60 FPS on a docked Switch, those hackers have given themselves a substantial upgrade. What's more, they're able to run the game at a staggering 4K 60 FPS. Although The Legend of Zelda: Skyward Sword HD was just released on Nintendo Switch, experienced emulation enthusiasts have managed to port the game to PC as well.
