Super Mario Odyssey can now be played on PC without an emulator. The fan project Power Moon Recomp went up on GitLab on November 2 and was already at version 0.2.0 by November 3. It's a native port for Windows and Linux: the Switch game's code is translated to C ahead of time and compiled into a regular program, with graphics running on Vulkan. According to the author, the whole game has been played through, every kingdom, the bosses, the 2D and 8-bit sections, the ending and the post-game. You need your own copy of version 1.0.0. The download contains no Nintendo code or assets.

What the port does: 4K, ultrawide and mods
The game runs at 60 fps, same as on Switch, and that's the ceiling: its logic is tied to the frame rate, so 120 fps would simply play at double speed. For 120 Hz and faster displays there's an experimental frame interpolation option that builds an in-between frame from the game's own state, at the cost of about half a frame of latency. Internal resolution goes up to 4x native, so at 1080p a 2x scale already gives you 4K. Slower PCs can go the other way, down to 25% with AMD FSR 1. On 21:9 and 32:9 monitors you see more of the world at the sides while the HUD stays centered.
Mods install from a tab in the menu without touching game files: costumes, models, textures, music, text, even levels. Only code mods are off the table. The menu sits on F1 or Esc, and both controllers and rebindable keyboard controls are supported.
What you need to run it
Windows 10 or 11, or Linux (Ubuntu 22.04, Debian 12, Fedora, Arch and SteamOS all work), a CPU with AVX2, meaning Intel Haswell or AMD Zen and newer, a GPU with Vulkan 1.3 and a current driver, 8 GB of RAM (16 recommended) and about 7 GB of disk space. The macOS build for Apple Silicon is an early test, so expect graphics issues there.
The game has to be version 1.0.0 with no updates, as exefs and romfs folders dumped from your own console. The author doesn't explain how to dump it. On first launch the program checks the version, copies about 6 GB and spends a few minutes recompiling the game code on your PC, after which it starts straight away. Windows may warn that the program isn't signed. There's also one known annoyance: the first time you enter an area, the driver compiles its shaders and the picture can freeze for a second or two.
Two caveats of my own. The author states plainly that the port was built with heavy help from an AI coding agent, directed and tested by a human. And this is a Nintendo game, from the company that sued the makers of the Yuzu emulator in 2024, so I wouldn't be surprised if the project vanished from GitLab. Don't go hunting for someone else's game dump either, that's piracy.
