Implements an API agnostic texture view based texture cache. Classes defined here are intended to be inherited by the API implementation and used in API-specific code. This implementation exposes protected virtual functions to be called from the implementer. Before executing any surface copies methods (defined in API-specific code) it tries to detect if the overlapping surface is a superset and if it is, it creates a view. Views are references of a subset of a surface, it can be a superset view (the same as referencing the whole texture). Current code manages 1D, 1D array, 2D, 2D array, cube maps and cube map arrays with layer and mipmap level views. Texture 3D slices views are not implemented. If the view attempt fails, the fast path is invoked with the overlapping textures (defined in the implementer). If that one fails (returning nullptr) it will flush and reload the texture. |

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.
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.
