I mean, all of these emulators are already very well archived and available from several sources, not to mention downloaded to the devices of millions of people. I highly doubt we would be in danger of losing any of them even if Nintendo were to sue literally all of them overnight. Well, except for things like Github issues and pull requests, nobody bothers to archive those unfortunately.
But yeah, IMO the danger is moreso that the attacks are leading to a massive chilling effect and loss of developer talent in the emulation community.
Huh, just realized Yuzu was GPLv3. That’s weird. Citra was GPLv2 and Yuzu is a Citra fork. Some of the Citra devs were Yuzu developers, but not all of them, so I wonder how they handled the relicensing. Yuzu had a CLA attributing copyright to the creators, so that wouldn’t have been a problem, but Citra had not such thing.
