Citra MMJ
What it is
Citra MMJ is an experimental, open-source Nintendo 3DS emulator and debugger written in C++. It emulates part of the console's hardware and can run or debug homebrew applications. The project README says it can also run many commercial games, although some may not reach a playable state; its compatibility definition requires a rating of at least “Okay” on its game compatibility list. The README names Windows, Linux, and macOS as platforms with actively maintained builds. Citra MMJ is a public fork of weihuoya/citra, and the README says most development takes place on GitHub. The project uses the GPLv2 license or any later version. Its repository currently has no releases, which matters for users looking there for packaged releases. The README directs people seeking help to an asking-for-help guide, and developers to Discord or the citra-dev channel on freenode. Interface translation is coordinated through Transifex and periodically incorporated upstream. The project says it accepts monetary donations and donated games or hardware to support development and infrastructure.
