Some games usually write memory pages currently used by the GPU, causing rendering issues (e.g. flashing geometry and shadows on Link's Awakening). To workaround this issue, Guest CPU writes are delayed until the command buffer finishes processing, but the pages are updated immediately. The overall behavior is: - CPU writes are cached until they are flushed, they update the page state, but don't change the modification state. Cached writes stop pages from being flushed, in case games have meaningful data in it. - Command processing writes (e.g. push constants) update the page state and are marked to the command processor as dirty. They don't remove the state of cached writes. |

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 and Linux. The emulator is capable of running several commercial games.
yuzu only emulates a subset of Switch hardware and therefore most commercial games do not run at full speed or are not fully functional.
Do you want to check which games are compatible and which ones are not? Please visit our Compatibility page!
yuzu is licensed under the GPLv2 (or any later version). Refer to the license.txt file included.
Check out our website!
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 also contact any of the developers on Discord in order to know about the current state of the emulator.
If you want to contribute to the user interface translation, please check out the yuzu project on transifex. We centralize translation work there, and periodically upstream translations.
Building
- Windows: Windows Build
- Linux: Linux 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.
