Redditor u/FloatingFalafel has released an open-source project called TVPort, a fork of the nxnative toolkit that recompiles Switch and Switch 2 games for the Apple TV 4K using a Mac, according to Engadget. The developer wrote that most games run essentially the same on the Switch, but some load textures into memory differently and need to be diagnosed and fixed before the game will run properly, noting they used Claude Opus 5.5 for the project. TVPort backs up save files to Mac or iCloud and allows users to choose between target framerates of 30 fps and 60 fps. Super Mario Odyssey is said to run at 60 fps with very slight stutters on occasion and some audio issues around waterfalls specifically, while Animal Crossing: New Horizons is seemingly limited to 30 fps with no issues encountered. More work is needed for The Legend of Zelda: Tears of the Kingdom, which experienced thermal throttling on Apple TV during tests; the developer stated heavier games like TOTK might never run on the Apple TV 4K 3rd-gen. The TVPort repository doesn't contain any game files, and users would have to provide their own files legally obtained from their own Switch cartridges.
