Nintendo’s Legal Hammer Quietly Kills Two Switch Emulators — Ryubing and Citron Are Gone

Nintendo has struck again. A fresh DMCA notice in February 2026 forced Ryubing into maintenance limbo and wiped Citron off the internet entirely. Here's what happened and what it means for emulation preservation.

Nintendo has claimed two more victims in its ongoing war against Switch emulation. On February 16, 2026, the developers behind both Ryubing and Citron — two of the most active Nintendo Switch emulators still standing after last year’s Yuzu collapse — halted development following a new DMCA notice from Nintendo. The story barely registered on mainstream gaming sites. For the preservation community, it’s a significant blow.

The Backstory: Yuzu Falls, Others Fill the Gap

To understand why this matters, you need to go back to March 2024. That was when Nintendo sued Tropic Haze LLC, the team behind Yuzu — at the time the most capable and widely used Switch emulator in existence. The lawsuit was swift and brutal. Nintendo argued Yuzu was built to circumvent its technological protection measures, and Tropic Haze settled almost immediately, agreeing to pay $2.4 million in damages and shut Yuzu down entirely. Its sister project, Citra — a 3DS emulator — was taken down at the same time.

The Yuzu shutdown sent shockwaves through the emulation scene but didn’t end it. Forks and successor projects emerged quickly, with Ryubing and Citron among the most prominent. Both positioned themselves as carrying the torch for Switch emulation, and both attracted active developer communities. That community is now significantly smaller.

What Happened on February 16

Nintendo’s latest DMCA action targeted both projects simultaneously. The results were different in each case, but neither outcome was good.

Ryubing’s lead developer announced the project would enter a basic maintenance phase, with no plans for major new features or a significant relaunch. The emulator will exist in a kind of legal limbo — technically still accessible for now, but no longer being actively pushed forward by the people who built it. Development, for all practical purposes, is over.

Citron’s fate was more final. Developer Zeph did not slow down — he stopped entirely. The project was taken offline, and Zeph deleted his Discord server, cutting off the community hub that had built up around the emulator. For users who relied on Citron, there is no longer an official home to return to.

For more on how Nintendo’s legal strategy has accelerated since Yuzu, The Verge’s deep-dive on the Yuzu settlement remains the clearest account of the template Nintendo has been using ever since.

Why Nintendo Keeps Winning

Nintendo’s legal approach to emulation is more aggressive than any other major platform holder, and it is working. The company’s argument has consistently centred not on whether emulation itself is legal — courts have generally held that it can be — but on the specific act of circumventing its encryption and protection systems, which falls under the Digital Millennium Copyright Act. That is a much harder argument for emulator developers to fight, especially when their tools are primarily used to play games that are still commercially available and actively sold by Nintendo.

The Yuzu settlement established a chilling precedent: Nintendo does not need to win in court to destroy a project. It simply needs to file. The legal costs alone are enough to shut most independent developers down, and the threat of a multi-million dollar judgment makes fighting back almost unthinkable for volunteer coders working on open-source tools in their spare time.

Ryubing and Citron both knew this. Neither team attempted to contest the DMCA notice. They folded quickly and quietly — exactly the outcome Nintendo’s legal strategy is designed to produce.

A useful primer on where emulation law currently stands: EFF’s overview of DMCA Section 1201 explains the specific provision Nintendo leans on most heavily, and why it gives platform holders such significant leverage over preservation and emulation projects.

The Preservation Argument Nintendo Ignores

The emulation community’s most compelling counter-argument has always been preservation. Nintendo has an inconsistent and often poor record of keeping older software accessible. Many Switch titles are digital-only and tied to online infrastructure that will eventually be switched off. Once Nintendo’s servers go down, certain games may become effectively unplayable through any official means.

Emulators are the primary mechanism through which those games survive. Without them, a meaningful portion of the Switch’s software library could become inaccessible within a generation. That is not a hypothetical — it has already happened with earlier Nintendo platforms, where out-of-print cartridges and defunct online services have made legitimate access to certain titles nearly impossible.

Nintendo has shown little interest in engaging with this argument. Its legal actions treat emulation almost exclusively as a piracy vector, a framing that conveniently sidesteps the preservation question entirely.

What’s Left Standing?

The Switch emulation scene is not dead, but it is contracting. Ryujinx, another major emulator, was taken down in October 2024 after Nintendo reached a private agreement with its lead developer. Sudachi, a Yuzu fork, continues to exist but operates in the same legal grey zone that has now consumed Ryubing and Citron.

Each Nintendo DMCA action makes the remaining projects more cautious, their developers more aware of the target on their backs, and the community around them less stable. The question is no longer whether Nintendo can shut down Switch emulation — it clearly can, and it is doing exactly that, methodically and quietly — but whether anything will survive long enough to fulfil the preservation role that commercial platforms have consistently failed to provide.
