Kirikae: Switch games recompiled into native PC programs

Kirikae, a recompiler written in Rust, turns a Switch game dumped from your console into a native Windows program, compiled on your PC.


Neither an emulator nor a single-game port

Kirikae (“switching over” in Japanese), by Brazilian developer Cor3Duo, came out as version 0.1.0 on 23 October 2026, followed by 0.1.1 the same day. The recompilations of recent months each targeted one game; Kirikae is a general tool: you give it a Switch game, it makes a Windows executable out of it.


How it works

• it reads the game's executable, translates every ARM64 instruction and compiles the whole thing into PC code with Cranelift, in under a minute according to the author;
• code the analysis did not find goes through an interpreter, and the next build picks it up;
• a custom engine replaces the console: the Horizon system, services, the Maxwell GPU on Vulkan, sound and video.

The author says it already runs complete commercial games, but gives no list, and warns that only a handful have been tried: expect crashes and rendering glitches.


What you need

• Windows 10 or 11 64-bit and a Vulkan 1.3;
• Rust and the Visual Studio build tools: games are compiled on your machine;
• a game dumped from your own console and already decrypted (for example with nxdumptool).

Kirikae ships, downloads and decrypts no game files, and the executable it produces must not be shared. The project is licensed under MIT or Apache 2.0. Dumping your games requires a modded Switch: see our Atmosphère tutorial.
