yuzu emulator

yuzu is an experimental open-source emulator for the Nintendo Switch from the creators of Citra.

It is written in C++ with portability in mind, with builds actively maintained for Windows, Linux and macOS. The emulator is currently only useful for homebrew development and research purposes.

yuzu only emulates a subset of Switch hardware and therefore is generally only useful for running/debugging homebrew applications. At this time, yuzu cannot play any commercial games without major problems. yuzu can boot some games, to varying degrees of success, but does not implement any of the necessary GPU features to render 3D graphics.

yuzu is licensed under the GPLv2 (or any later version). Refer to the license.txt file included.

For development discussion, please join us on Discord.

Development

Most of the development happens on GitHub. It's also where our central repository is hosted.

If you want to contribute please take a look at the Contributor's Guide and Developer Information. You should as well contact any of the developers on Discord in order to know about the current state of the emulator.

Building

Windows: Windows Build
Linux: Linux Build
macOS: macOS Build

Support

We happily accept monetary donations or donated games and hardware. Please see our donations page for more information on how you can contribute to yuzu. Any donations received will go towards things like:

Switch consoles to explore and reverse-engineer the hardware
Switch games for testing, reverse-engineering, and implementing new features
Web hosting and infrastructure setup
Software licenses (e.g. Visual Studio, IDA Pro, etc.)
Additional hardware (e.g. GPUs as-needed to improve rendering support, other peripherals to add support for, etc.)

We also more than gladly accept used Switch consoles, preferably ones with firmware 3.0.0 or lower! If you would like to give yours away, don't hesitate to join our Discord and talk to bunnei. You may also contact: donations@yuzu-emu.org.
