Players of Legend of Zelda on Steam Deck may have to see their favorite game taken down soon. That is after Nintendo took legal action against the developers of Yuzu in the US federal court, aiming to halt its operations permanently.

In the lawsuit, first identified by Stephen Totilo, Nintendo contends that Yuzu violates the Digital Millennium Copyright Act (DMCA) by infringing upon anti-circumvention and anti-trafficking provisions. Nintendo asserts that Yuzu is primarily crafted to bypass various layers of Nintendo Switch encryption, enabling users to play copyrighted Nintendo games without authorization.

In the statement, Yuzu is an emulator primarily designed to allow users to play copyrighted Nintendo Switch games on platforms like the Steam Deck. It can bypass various layers of Nintendo Switch encryption, enabling users to run these games without authorization from Nintendo. 

Additionally, Yuzu offers functionalities such as compatibility testing with official Nintendo Switch games like Xenoblade and providing detailed instructions on running obtained Nintendo Switch games unlawfully. 

However, it's important to note that the legality of using Yuzu and similar emulators for playing copyrighted games without permission is contentious and subject to legal scrutiny.

Nintendo demands a permanent injunction against Yuzu and seeks control over its domain names, URLs, chatrooms, and social media platforms. Additionally, Nintendo requests the transfer of the domain name yuzu-emu.org and even the destruction of its hard drives, alongside substantial financial damages.

While the legality of emulators is a nuanced issue, recent advancements in encryption technology pose challenges. Unlike older cases where emulators were deemed legal under certain circumstances, modern emulators face scrutiny due to their intricate encryption circumvention techniques.

Nintendo accuses Yuzu of facilitating piracy on a large scale by offering detailed instructions on running obtained Nintendo Switch games. 

Moreover, Nintendo alleges that Yuzu's developers have directly extracted Nintendo Switch games to test their emulator's functionality, further aggravating the infringement.

The crux of Nintendo's argument lies in Yuzu's alleged primary purpose of granting unauthorized access to Nintendo Switch games. This would violate DMCA regulations if proven, potentially jeopardizing Yuzu's legal standing.

What Can Yuzu Emulator Do?

Despite potential legal ambiguity, Yuzu may opt for a settlement rather than risk a prolonged legal battle with Nintendo. Similar cases have prompted other emulator developers to cease their projects upon facing legal pressure from Nintendo.

As of today, the developers of Yuzu Emulator have yet to respond to the lawsuit from Nintendo.
