Sort of. Nintendo’s lawyers showed up at the house of the lead dev and he nuked everything he had access to afterwards, which is all we really know, but unlike Yuzu there were no court filings or takedowns or anything. Forks of Ryujinx are still just up on Github.
The actual answer to that question is that the Switch 2 will be out soon. Nintendo doesn’t actually want to go to court over emulators, because there’s a real chance they lose. They were willing to push the devs with Switch emulators though, because that’s the current console generation, and that REALLY pissed them off. They’ve basically accepted that emulators are inevitable even if they don’t like it, but emulating the console they are currently releasing new games for was a step too far as far as they’re concerned.
Well, part of the problem with modern emulators is that more and more consoles are just relying on regular off the shelf hardware components. That means more of what makes them unique is in software, which is a problem, because emulating software is a lot harder to defend legally, especially in the US and Japan.
So, realistically, the sooner you see a Switch 2 emulator pop up, the faster it’s likely to be taken down by Nintendo’s lawyers.
Also, they’re probably not going to screw up and leave in a hardware recovery mode that bypasses all their security again, which is a big part of why Yuzu could get started so fast.
