UNITED STATES DISTRICT COURT DISTRICT OF RHODE ISLAND
NINTENDO OF AMERICA INC., Plaintiff, v. TROPIC HAZE LLC, Defendant. NO. COMPLAINT JURY DEMAND
PRELIMINARY STATEMENT
Plaintiff Nintendo of America Inc. (“Nintendo of America Inc.” or “Plaintiff”), by and through its counsel, on personal knowledge as to its own actions and on information and belief as to the actions, capabilities, and motivations of others, hereby alleges as follows: 1.
Nintendo of America Inc., a wholly-owned subsidiary of Nintendo Co., Ltd., markets and distributes electronic video game consoles, games, and accessories developed by Nintendo Co., Ltd., including the Nintendo Switch, Nintendo Switch Lite, and Nintendo Switch OLED consoles (collectively the “Nintendo Switch”). Nintendo of America Inc. and Nintendo Co., Ltd. are together referred to herein as “Nintendo.” Nintendo also makes award-winning and beloved video games that can be played only on the Nintendo Switch, including such well-known franchises as
Mario
and
The Legend of
Zelda
. Nintendo has sold over 139 million Nintendo Switch consoles (and counting), making it the third most popular video game console of all time. 2.
Defendant Tropic Haze LLC is an entity that owns, develops, and operates “Yuzu,” a video game emulator for Nintendo Switch games. A video game emulator is a piece of software that allows users to unlawfully play pirated video games that were published only for a specific console on a general-purpose computing device. Yuzu allows Nintendo Switch games, which Nintendo authorizes for play solely on Nintendo Switch consoles, to be played

2 on Windows, Linux, or Android systems. That means that people are able to play pirated Nintendo Switch games on PCs and Android devices, which would not otherwise be possible due to the protections that Nintendo has put into place on its consoles and games. 3.
To protect its intellectual property rights and its investment, as well as the investments of its third-party developers, Nintendo designed the Nintendo Switch and Nintendo Switch video games with sophisticated security features, or technological measures (sometimes referred to as technological protection measures, or “TPMs”), meant to prevent people from playing unauthorized or pirated copies of Nintendo’s video games, whether on Nintendo Switch consoles or on other platforms. Specifically, every Nintendo Switch video game stored on a Nintendo physical cartridge or on a Nintendo Switch console as a digital download is secured with multiple technological measures, including encryption that scrambles the audiovisual content in the game file to make it unreadable without the use of proprietary cryptographic keys. In the ordinary course of operation, an authentic Nintendo Switch console will use certain cryptographic keys available to the console, commonly referred to as the “prod.keys,” to decrypt other cryptographic keys associated with games, and then use those keys to decrypt lawfully-purchased games during runtime. Only if the games are dynamically decrypted during operation of the console may the user play those games. 4.
Nintendo also has technological measures on the Nintendo Switch console itself, including additional layers of encryption, which prevent users from unlawfully accessing or modifying the console—including to procure the prod.keys—and from accessing or copying games stored on the console or on a cartridge inserted in the console. 5.
Yuzu unlawfully circumvents the technological measures on Nintendo Switch games and allows for the play of encrypted Nintendo Switch games on devices other than a Nintendo Switch. Yuzu does this by executing code necessary to defeat Nintendo’s many technological measures associated with its games, including code that decrypts the Nintendo Switch video game files immediately before and during runtime using an illegally-obtained

3 copy of prod.keys (that ordinarily are secured on the Nintendo Switch). Users obtain the prod.keys either through unlawful websites or by unlawfully hacking a Nintendo Switch console. The lead developer of Yuzu—known online under the alias “Bunnei”—has publicly acknowledged most users pirate prod.keys and games online, and Yuzu’s website provides instructions for its users telling them how to unlawfully hack their own Nintendo Switch and how to make unauthorized copies of Nintendo games and unlawfully obtain prod.keys. Only because Yuzu decrypts a Nintendo Switch game file dynamically during operation can the game be played in Yuzu.
In other words, without Yuzu’s decryption of Nintendo’s encryption, unauthorized copies of games could not be played on PCs or Android devices
. 6.
With Yuzu in hand, nothing stops a user from obtaining and playing unlawful copies of virtually any game made for the Nintendo Switch, all without paying a dime to Nintendo or to any of the hundreds of other game developers and publishers making and selling games for the Nintendo Switch. In effect, Yuzu turns general computing devices into tools for massive intellectual property infringement of Nintendo and others’ copyrighted works. 7.
Defendant employs several developers who operate as the company’s agents, including Yuzu’s author and lead developer, Bunnei. Defendant traffics in the Yuzu software on a website YUZU-EMU.ORG, on GITHUB.COM, and, recently, on Google Play (an app store for Android devices). YUZU-EMU.ORG provides detailed instructions
and FAQs on how to install Yuzu and get it running with unlawful copies of Nintendo Switch games. YUZU-EMU.ORG also has a blog section with regular posts about updates to the software (which include discussion of different Nintendo games running in the emulator), a list of thousands of Nintendo Switch games that Yuzu developers have tested in Yuzu and confirmed can be played, and screenshots of Nintendo Switch games being played in the emulator. The website additionally links to a variety of other circumvention software that can hack into the Nintendo
