Moves the memory writes directly into QueryProcessMemory instead of letting the wrapper function do it. It would be inaccurate to allow the handler to do it because there's cases where memory shouldn't even be written to. For example, if the given process handle is invalid. HOWEVER, if the memory writing is within the wrapper, then we have no control over if these memory writes occur, meaning in an error case, 68 bytes of memory randomly get trashed with zeroes, 64 of those being written to wherever the memory info address points to, and the remaining 4 being written wherever the page info address points to. One solution in this case would be to just conditionally check within the handler itself, but this is kind of smelly, given the handler shouldn't be performing conditional behavior itself, it's a behavior of the managed function. In other words, if you remove the handler from the equation entirely, does the function still retain its proper behavior? In this case, no. Now, we don't potentially trash memory from this function if an invalid query is performed. |

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.
