An experimental open-source Nintendo 3DS emulator/debugger written in C++. Citra is written with portability in mind, with builds actively maintained for Windows, Linux and OS X. At this time, it only emulates a subset of 3DS hardware, and therefore is generally only useful for booting/debugging very simple homebrew demos. Citra is licensed under the GPLv2. Refer to the license.txt file included. Please read the FAQ before getting started with the project.
For development discussion, please join us @ #citra on freenode.
If you want to contribute please take a took at the Contributor's Guide, Roadmap and Developer Information pages. You should as well contact any of the developers in the forum in order to know about the current state of the emulator.
