This has never been tested in court - the bleem case was before DMCA. Nintendo is always playing the copyright and security circumvention card and no one wants to fight it (understandably). Details of the Ryujinx case are not public but I guess they used the Yuzu case as a threat.
Yuzu was killed because Nintendo sued Tropic Haze LLC (the company behind Yuzu) and issued a permanent injunction.
> Apple sued security start-up Corellium last year, accusing it of violating copyright law for offering researchers access to “virtual” iPhones that can help them find bugs in iOS products. Now, a federal judge in Florida has tossed Apple’s copyright complaint, giving Corellium a major victory in its legal battle against the tech giant.
I wouldn't be surprised if they are legal (e.g. look at Wine), but in a US court Nintendo will happily make it so expensive for a defendant that they have no choice but to concede.
I can see that killing development by Tropic Haze, but the repositories are gone and not just stopped/locked/archived, and all forks seem to be eliminated too. I didn't think it was possible to that thoroughly kill an open source project, but nintendo apparently managed somehow.
Because there is an injunction against the Yuzu source code and it's radioactive so no one touches it. There are a few forks but none active (and the devs of them just slap a new logo on it and call it a day).
