I would say that game over, but you never know. In the world of games and for weeks now, the news is that Yuzu and Citra have disappeared because Nintendo beat them in court, but also that new options came out such as water to continue, at least, with Yuzu. HE I could try an unofficial release and they updated their GitLab page to add the installers they would soon add to their website, but the joy did not last long.
If we go to the previous link and hover over "Download", if the browser supports this function we will see the link that leads to https://gitlab.com/suyu-emu/suyu/-/releases, but if we click there, right now it asks us for an account to continue. Until recently, the 404 error appeared, that is, it did not exist, and this probably remains the case for a DMCA complaint that has ended with the repository being removed. In theory.
Suyu also disappears
The developers, if they are because it was said no, they wanted to get healthy and They removed both keys and firmware from the emulator. The intention was to survive, and they left the task of obtaining those components to be able to play Nintendo Switch titles on other devices up to the user. But this does not seem to have been enough.
So and how they publish in X, GitLab says that "We determined that you forked a public repository that we previously received a DMCA report against. If you want to regain access to your account, you are required to delete the following project from your account […]. Once you accept these terms, you will have 24 hours to delete the content«.
From the message we understand something that we already knew: Suyu is Yuzu with another name. The problem is that they have made the direct copy, and they can probably re-upload it if they make any clear changes, but this is pure speculation. The easiest thing is to think that Suyu has a difficult time moving forward.
Meanwhile and as we have said on other occasions, Ryujinx continues to exist, which is now the best option to emulate Switch titles.
