Nintendo's Lawsuit Ends Yuzu: A $2.4 Million Settlement Shuts Down the Switch Emulator
Nintendo sued Yuzu developer Tropic Haze in February 2024 alleging the Switch emulator existed to facilitate piracy at scale. Within days, Yuzu was gone — and its sister project Citra went down with it.
On February 26, 2024, Nintendo of America filed suit against Tropic Haze LLC, the developer of Yuzu, a popular open-source Nintendo Switch emulator, in federal court in Rhode Island. Within days, the case ended in a settlement that shut the project down entirely.
Nintendo’s claims
Nintendo’s complaint alleged that Yuzu was designed to circumvent the Switch’s encryption and technical protection measures under the DMCA, and that its primary real-world use was enabling large-scale piracy of Switch games — including, notably, letting people play unreleased and pirated copies of games (Nintendo’s complaint specifically cited The Legend of Zelda: Tears of the Kingdom leaking and being played en masse via Yuzu before its official release) ahead of their official release dates.
The settlement
Rather than litigate, Tropic Haze settled quickly, agreeing to pay Nintendo $2.4 million and to permanently stop developing Yuzu or any future Switch-emulation software. As part of the settlement terms, Tropic Haze also surrendered its websites, domains, and source code repositories related to the emulator.
Citra went down too
Tropic Haze also developed Citra, a Nintendo 3DS emulator, and the same shutdown announcement discontinued Citra alongside Yuzu — its Discord server, Patreon, and code repositories were taken down “effective immediately” as part of the same wind-down.
Why this sent a shockwave through the emulation community
Yuzu was, at the time, one of the most widely used and actively developed console emulators in existence, forked and relied upon by numerous other Switch-emulation projects. Its abrupt shutdown via a fast legal settlement — rather than a drawn-out court fight over fair use, the kind of dispute that produced favorable precedent in cases like Sony v. Connectix decades earlier — demonstrated that a sufficiently aggressive legal strategy focused on piracy facilitation, rather than the emulation technique itself, could end a major open-source emulation project within days.
