The previous code had some minor issues with it, really not a big deal, but amending it is basically 'free', so I figured, "why not?". With the standard container maps, when: map[key] = thing; is done, this can cause potentially undesirable behavior in certain scenarios. In particular, if there's no value associated with the key, then the map constructs a default initialized instance of the value type. In this case, since it's a std::shared_ptr (as a type alias) that is the value type, this will construct a std::shared_pointer, and then assign over it (with objects that are quite large, or actively heap allocate this can be extremely undesirable). We also make the function take the region by value, as we can avoid a copy (and by extension with std::shared_ptr, a copy causes an atomic reference count increment), in certain scenarios when ownership isn't a concern (i.e. when ReserveGlobalRegion is called with an rvalue reference, then no copy at all occurs). So, it's more-or-less a "free" gain without many downsides. |

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.
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 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.
