They haven't gotten the money yet, and they probably never will get the full amount.
They probably won't even be taking anyone else to court, either. Ryujinx will probably make major changes or shut down entirely to avoid getting sued in the first place.
That's on paper. It's extremely unlikely that they set an LLC with millions of dollars in assets. The reason they set up the LLC was that if they got sued they could settle for any amount, knowing that they would just declare bankruptcy and pay nothing except their legal fees (which, having settled immediately, are very low)
Yeah it kinda is. You can fork projects all day but assembling a team of intelligent and motivated individuals to actually maintain the project is a whole other problem. Add to that the fear of litigation and multi-million dollar lawsuits and I'd say Switch emulation will be all but dead in the near future.
Projects like this should be self-hosted & encourage contributors to set up their own self-hosted mirrors to make sure the code is both distributed & decentralized which users/makers have full control over their platform.
And that's probably why Yuzu didn't stand up to Nintendo. They probably had enough areas for Nintendo to attack that fighting it could leave the emulator community worse off if it goes to trial. Why risk the money to fight something unless you're sure you can win?
