This also includes ceasing development and destroying their copies of the code.

The GitHub repo page for Yuzu now returns a 404, as well. In addition, the repo for the Citra 3DS emulator was also taken down.

As of at least 23:30 UTC, Yuzu's website and Citra's website have been replaced with a statement about their discontinuation.
