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 freenode.


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.



We happily accept monetary donations or donated games and hardware. Please see our donations page for more information on how you can contribute to Citra. Any donations received will go towards things like: * 3DS consoles for developers to explore the hardware * 3DS games for testing * Any equipment required for homebrew * Infrastructure setup

We also more than gladly accept used 3DS consoles! If you would like to give yours away, don't hesitate to join our Discord server and talk to bunnei.
