They are still running afowl of the anti circumvention rules in the dmca. Just saying you have to provide your own keys isn't enough.
A switch emulator that wants to be safe from nintendo has to have no capability of circumventing the copyright protection mechanisms nintendo employs.
Look at vlc for inspiration. It can play blurays, it can't circumvent the copyright protection of blurays. But if you provide the keys and the library that decodes the content then it can play them just fine. This keeps vlc safe.
ok but how does the bluray library stay safe? its still a similar problem. for piracy sites, a lot of them seem to deal with it by just having it be hosted in a country that doesnt care enough to shut them down.
This appears incorrect. Multiple emulators have ways to circumvent the copyright protection mechanism. None of them are being hit. Dolphin legit has the keys in their package. It's why Steam didn't platform them, but Nintendo knows and Dolphin is not changing. It would be literally the cost of the letter to get Dolphin to change. Nintendo hasn't even sent that letter.
What Yuzu did wrong was outside of "anti circumvention rules" that you seem afraid of.
Sorry but it's not wrong. The anti circumvention clause in the drmc was the direct complaint from nintendo against yuzu. Please research that clause and the legal prior art, especially against decss. I've had this conversation too many times to repeat it again.
"I've done it too many times to repeat it again" Really?
Isn't that kind of beneath you? That's the type of shit someone would say on a playground.
Besides which the full complaint doesn't appear to be available anywhere, but what has been shown has not said what you're claiming.
However other people might have more knowledge about this situation than you seem to, besides which other pieces that have been revealed since the original complaint have shown it's not just about the ability to circumvention technology. So you know.. maybe read more, or stop acting like you have all the answers when you don't?
On the other hand consider if it was exactly what you say it is, why isn't Cemu and Ryujinx getting their own version of the note... hint: it's not just about the circumvention...
I'm just tired of explaining it over ten comments in a thread, I'm sorry I can't just give you all the answers you want. I've my own stuff going on. I hope I gave you enough information to go find out the answers.
That's assuming the Suyu team is based on the USA, where the DMCA can screw them over. As they're hosting their code on GitLab istead of GitHub, it may hint they got this covered.
