Ruzu
What it is
Ruzu is a free, open-source Nintendo Switch emulator for Windows, macOS, Linux, Ubuntu, and Steam Deck desktop packages. Written in Rust, it provides a graphical library for browsing game directories, managing per-game settings, and viewing detected updates and add-ons. The interface accepts controller navigation as well as keyboard and mouse input, with themes, translations, configurable hotkeys, and game-list display choices. Graphics support includes Vulkan and OpenGL, plus an experimental native Metal backend on macOS. Ruzu can run homebrew applications through graphical and command-line frontends and supports ARM32 and ARM64 guest execution through its dynamic recompiler. The latest listed release is v0.1.1-rc4, a pre-release. Compatibility and performance vary by game, hardware, and graphics backend, with bugs, crashes, and incomplete features expected.
