piracy (in the sense of sharing copyrighted content with others) and bypassing DRM is illegal in nearly every country of the world, subject to the Berne convention and the WIPO treaty
The organization selected the European Union for their headquarters and computer infrastructure, due to members' concerns that a software project repository hosted in the United States could be removed if a malicious actor made bad faith copyright claims under the Digital Millennium Copyright Act.
In June 2022 the Software Freedom Conservancy's"Give Up Github" campaign (in response to the GitHub Copilot licensing controversy) promoted Codeberg as an alternative to GitHub.
Germany isn't any better though, in fact, Germany has even more restrictive and absurd copyright law than the US.
Here:
The manufacture, import, distribution, sale, rental, advertising with a view to sale or rental and the possession for commercial purposes of devices, products or components as well as the provision of services which:
are the subject of promotion, advertising or marketing with the aim of circumventing effective technological measures, or
have only a limited economic purpose or benefit other than the circumvention of effective technological measures, or
are primarily designed, manufactured, adapted or provided for the purpose of enabling or facilitating the circumvention of effective technological measures. \
is prohibited.
And I'm certain that Nintendo will choose the correct court to argue any modern emulator is violating this to sue in. After all, one court in particular is notorious for ignoring all reason when it comes to copyright. For instance, it ruled that you are violating copyright for publishing photos of your home if your walls have a photo wallpaper. After all, making and posting an image of the copyrighted design of the wallpaper on your website, even if the wallpaper is just in the background, constitutes an illegal copy.
The commercial use (e.g. sale, rental) is prohibited according to your cited text.
The manufacture, import, distribution, sale, rental, advertising with a view to sale or rental and the possession for commercial purposes of devices, products or components as well as the provision of services which: [...]
And while the LG Köln (Cologne) sided with the copyright owner of the wallpaper, other LGs and the OLG Düsseldorf - a higher court - said otherwise:
The case I ZR 140/23 is really meta: A woman posted a screenshot of a website of a tennis center online; the documented website also contains a photograph of the guest room of the tennis center, whose wall is (in)decorated with a photo wallpaper on which a picture motif is reproduced to which the photographer claims rights via his company registered in Canada.
How about several decades worth of emulators that Nintendo hasn't touched? As the article points out, Yuzu both profited off their emulator and had step by step guides on how to pirate games. Emulators are legal, piracy is not. Nintendo suing Yuzu was not surprising or a change in precedent. Other emulators are not concerned by this because they play by the rules, and I don't see why we should be worried about decades of precedence changing when yuzu was sued on grounds that every other emulator maker already knew were red lines.
When you provide an emulator you simply have to say "we do not condone piracy, this emulator is for hobbyist use only". Then let one of the hundreds of community resources provide the actual piracy instructions where Nintendo has to play whack a mole instead.
The problem is that even if you're possibly in the right, that doesn't stop Nintendo from suing you, because you have to also be able to afford to be right.
