After Nintendo sued Yuzu developer Tropic Haze in February 2024, emulator developers interviewed by Ars Technica said they were not abandoning emulation. Their confidence was not a legal ruling: interviewees described different precautions and beliefs about risk, while the Yuzu case itself ended in a settlement rather than a trial deciding whether emulation is generally lawful.
Why emulator developers said they were not deterred
For some interviewees, Nintendo’s lawsuit raised concerns that already shaped their work rather than introducing a wholly new threat. They described varying approaches: some kept projects private or limited access to builds; others focused on older, discontinued systems. These are individual developers’ practices and perceptions, not proof that any approach is legally safe.
Private projects and limited sharing
StrikerX3 told Ars that concern about Nintendo’s lawyers was one reason a Nintendo DS emulator he was working on remained private, with builds shared only with a handful of people. Other developers told the publication they believed living outside the United States might reduce their exposure to U.S. copyright law. One interviewee did not identify their country, and that comment does not establish what protections any particular jurisdiction provides.
Older systems and technical choices
Several developers drew a distinction between emulating a discontinued console and targeting an active commercial platform such as the Switch. Hobbyist developer Parsifal said: “There is a difference between emulating a 30-year-old system vs. a current one that’s actively making money.” He also expressed his own view that “Emulation is fine as long as you don’t infringe on copyright and trademarks.” Neither statement is a court’s interpretation of the law.

The developers and Ars also discussed whether projects distribute copyrighted code or instead rely on users’ own files, and whether encryption or circumvention is involved. The article noted that some older systems may not have encryption barriers and that some emulator teams reverse-engineered open-source BIOS or BootROM files rather than distributing copyrighted code. Those technical differences may matter to a particular dispute, but they do not by themselves settle the legality of a project or its users’ conduct.
Concerns about guidance for commercial games
Some interviewees criticized Yuzu’s public guidance and community support around running commercial games. An anonymous emulator developer told Ars: “I think Yuzu definitely crossed some line when they started explaining how to actually pirate games.” That is the interviewee’s criticism, not a finding by a court.

What Nintendo alleged in its lawsuit
Nintendo filed its complaint against Tropic Haze LLC, Yuzu’s developer, in federal court in Rhode Island on February 26, 2024. It alleged that Yuzu facilitated circumvention and copyright infringement. A complaint presents one party’s allegations; it is not a judicial finding.
Among the figures Nintendo put in the filing, it alleged that The Legend of Zelda: Tears of the Kingdom had been downloaded more than one million times between May 1 and May 10, 2023, with another million attempted downloads. Nintendo also alleged that Yuzu’s Patreon membership doubled between May 1 and May 12, 2023, and characterized the new paid memberships as numbering in the thousands. These are claims in Nintendo’s complaint, not independently verified or adjudicated counts.

What the Yuzu settlement resolved
On March 4, 2024, Tropic Haze agreed to a consent judgment. GameSpot reported that the agreement included a $2.4 million payment, an end to Yuzu development and distribution, and shutdown of the project’s channels and site. Yuzu’s public statement said: “Piracy was never our intention, and we believe that piracy of video games and on video game consoles should end.” The statement also said the project’s repositories, Patreon accounts, Discord servers, and websites would be taken offline; it reflects the developers’ position, not a judicial finding about their intent.
The case settled without a trial on the merits. As Ars Technica’s contemporaneous legal analysis explained, Nintendo’s case focused on claims about circumvention, instructions, and alleged infringement. That analysis also noted that emulators can have lawful uses, including homebrew. The settlement did not establish a general rule that all emulation is illegal—or that every emulator or use is lawful. Questions depend on the facts and applicable law; this account is not individualized legal advice.

How the dispute affected related projects afterward
The Yuzu settlement did not end all enforcement activity involving Switch emulation. The following reports are dated snapshots, not a comprehensive or current inventory of projects, notices, or repository availability.
April 2024: servers and decryption-related projects
In April 2024, Ars reported that Discord had shut down discussion servers associated with Yuzu forks Suyu and Sudachi, and that GitHub had removed projects related to Switch software decryption. The report described these events as aftershocks of the Yuzu case and discussed restrictions in the settlement concerning Yuzu and clones using its code. See Ars Technica’s April 2024 report for that period’s account.

February 2026: further GitHub notices
On February 14, 2026, PC Gamer reported DMCA notices affecting multiple Switch emulator repositories on GitHub and quoted community frustration. It also said some self-hosted repositories and project websites remained available at that time. Availability can change, so those details describe the report’s date rather than the present status of any particular project. PC Gamer’s February 2026 report covers that later snapshot.
