Super Mario Odyssey

Yes. The project distributes no game data — you supply your own copy or dump. Every project in this scene works this way, and it is what lets them stay publicly hosted on GitHub.

This is a static recompilation: tooling mechanically translates the original console binary into PC code rather than rewriting the game by hand. The result runs natively, typically with an uncapped framerate and widescreen.

Native ports and recompilations skip CPU emulation entirely, so they are usually far lighter than an emulator for the same console. With no published measurement for this project, though, any estimate would be guesswork — test it on your own machine.

No release has been published, so there is nothing to say which systems it runs on. The game originally shipped on Nintendo Switch.

The project is public and open source, maintained by Coz-0, and contains nothing from the commercial game. Responsibility for the game copy you use is yours — which is why the developers require you to supply your own.
