* This is a pretty large commit that aims to solve some issues with the current format system * The instance now builds at application initialization an array of format traits for each pixel format that includes information such as blit/attachment/storage support and fallback formats * The runtime doesn't ask the instance for formats but receives these traits and can dedice on its own what to build For now we do the same as before, we require both blit and attachment support * Morton swizzling also sees many bug fixes. The previous code was very hacky and didn't work for partial texture updates. It was also inconsistent, as it would take a tiled_buffer and write to the middle of linear * Now the functions have been greatly simplified and adjusted to work better with std::span. This fixes out of bounds errors and texture glitches (like the display in Mario Kart 7)

Citra
Citra is an experimental open-source Nintendo 3DS emulator/debugger written in C++. It is written with portability in mind, with builds actively maintained for Windows, Linux and macOS.
Citra emulates a subset of 3DS hardware and therefore is useful for running/debugging homebrew applications, and it is also able to run many commercial games! Some of these do not run at a playable state, but we are working every day to advance the project forward. (Playable here means compatibility of at least "Okay" on our game compatibility list.)
Citra is licensed under the GPLv2 (or any later version). Refer to the license.txt file included. Please read the FAQ before getting started with the project.

For development discussion, please join us on our Discord server or at #citra-dev on libera.
Releases
Citra has two main release channels: Nightly and Canary.
The Nightly build is based on the master branch, and contains already reviewed and tested features.
The Canary build is based on the master branch, but with additional features still under review. PRs tagged canary-merge are merged only into the Canary builds.
Both builds can be installed with the installer provided on the website, but those looking for specific versions or standalone releases can find them in the release tabs of the Nightly and Canary repositories.
Currently, development and releases of the Android version are in a separate repository.
A Flatpak for Citra is available on Flathub. Details on the build process can be found in our Flathub repository.
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 in the forum in order to know about the current state of the emulator because the TODO list isn't maintained anymore.
If you want to contribute to the user interface translation, please check out the citra project on transifex. We centralize the translation work there, and periodically upstream translations.
Building
- Windows: Windows Build
- Linux: Linux Build
- macOS: macOS Build
