TVPort is an experimental project that adapts Nintendo Switch game code for Apple TV 4K. FloatingFalafel reportedly presented it on November 4, 2026, and the developer’s results include Super Mario Odyssey at 60 frames per second (fps). The figures are tied to specific games and come with performance caveats. Infobae reported the project and its results.
How TVPort adapts Switch games for Apple TV 4K
TVPort is based on nxnative. Instead of running a conventional Nintendo Switch emulator, the project adapts game code for Apple processors and graphics for Metal, Apple’s graphics technology. Infobae also reports that FloatingFalafel used Claude Opus 5.5 as a coding aid. The project is experimental and has no official affiliation with Apple or Nintendo.
Foli Tech discusses TVPort in Spanish-language commentary:
The reported results vary by game
Infobae attributes the performance figures to tests shared by TVPort’s developer. Super Mario Odyssey was reported at 60 fps on Apple TV 4K (3rd generation), with occasional stutters and audio problems in some areas, especially near waterfalls. Animal Crossing: New Horizons was reported at 30 fps, with no major problems noted during the described tests. The Legend of Zelda: Tears of the Kingdom was reported at 30 fps in handheld mode with 3D resolution reduced to 75%; performance also drops as the device heats up.
| Game | Reported result | Conditions and limitations |
| Super Mario Odyssey | 60 fps | Apple TV 4K (3rd generation); occasional stutters and audio problems in some areas, especially near waterfalls. |
| Animal Crossing: New Horizons | 30 fps | The developer reported no major problems during the described tests. |
| The Legend of Zelda: Tears of the Kingdom | 30 fps | Handheld mode; 3D resolution reduced to 75%; performance drops as the device heats up. |
Treat each frame-rate figure as a result for a particular game and setup, not as a compatibility promise for Switch games generally.
A separate Mario Kart build uses a different route
A separate post by cultomo describes an nxnative-based Apple TV build running Mario Kart 8 Deluxe version 4.0.1 with DLC at 720p on an A15 Apple TV 4K. That is a distinct experiment, not a TVPort result. The author describes the build as experimental; the post says other games are not guaranteed and notes that new tracks can stutter the first time they run while shaders compile. (cultomo’s post).
For this separate build, the post lists an Apple Silicon Mac, macOS 26.6 or later, full Xcode 27 with the tvOS SDK, a controller, and the user’s own game dump, update, and keys. It also recommends allowing roughly 30 GB of extra storage for Mario Kart 8 Deluxe.
What the reported TVPort setup requires
Infobae lists an Apple Silicon Mac running macOS 26.6 or later, Xcode 27.1, and an Apple TV 4K compatible with tvOS 26 or later, with Developer Mode enabled. Users must provide their own game files and keys; TVPort does not include or distribute Nintendo games.
