Despite this, the one fork that continues, and will continue without takedown is Ryubing - by Greemdev. This is created by an original member of the Ryujinx team. It’s safe, the code is beyond reproach (and violates zero laws or Nintendo code) and actually brings helpful updates.

Still…shitty news. And more indication that the Switch 2’s architecture will be damn similar to that of this current Switch. Them taking emulators down means the upcoming games have a solid chance of being emulatable on release. But…that’s my own (and others’) conjecture, so we’ll see when the time comes.
