There are still some other issues not addressed here, but it's a start. Workarounds for false-positive reports: - `RasterizerAccelerated`: Put a gigantic array behind a `unique_ptr`, because UBSan has a [hardcoded limit](https://stackoverflow.com/questions/64531383/c-runtime-error-using-fsanitize-undefined-object-has-a-possibly-invalid-vp) of how big it thinks objects can be, specifically when dealing with offset-to-top values used with multiple inheritance. Hopefully this doesn't have a performance impact. - `QueryCacheBase::QueryCacheBase`: Avoid an operation that UBSan thinks is UB even though it at least arguably isn't. See the link in the comment for more information. Fixes for correct reports: - `PageTable`, `Memory`: Use `uintptr_t` values instead of pointers to avoid UB from pointer overflow (when pointer arithmetic wraps around the address space). - `KScheduler::Reload`: `thread->GetOwnerProcess()` can be `nullptr`; avoid calling methods on it in this case. (The existing code returns a garbage reference to a field, which is then passed into `LoadWatchpointArray`, and apparently it's never used, so it's harmless in practice but still triggers UBSan.) - `KAutoObject::Close`: This function calls `this->Destroy()`, which overwrites the beginning of the object with junk (specifically a free list pointer). Then it calls `this->UnregisterWithKernel()`. UBSan complains about a type mismatch because the vtable has been overwritten, and I believe this is indeed UB. `UnregisterWithKernel` also loads `m_kernel` from the 'freed' object, which seems to be technically safe (the overwriting doesn't extend as far as that field), but seems dubious. Switch to a `static` method and load `m_kernel` in advance. |

yuzu
yuzu is the world's most popular, open-source, Nintendo Switch emulator — started by the creators of Citra.
It is written in C++ with portability in mind, and we actively maintain builds for Windows, Linux and Android.

Compatibility
The emulator is capable of running most commercial games at full speed, provided you meet the necessary hardware requirements.
For a full list of games yuzu support, please visit our Compatibility page
Check out our website for the latest news on exciting features, monthly progress reports, and more!
Development
Most of the development happens on GitHub. It's also where our central repository is hosted. For development discussion, please join us on Discord.
If you want to contribute, please take a look at the Contributor's Guide and Developer Information. You can 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 project, please check out the yuzu project on transifex. We centralize translation work there, and periodically upstream translations.
Building
- Windows: Windows Build
- Linux: Linux Build
Download
You can download the latest releases automatically via the installer on our downloads page.
Support
