“Nintendo is committed to protecting the hard work and creativity of video game engineers and developers,” a spokesperson for Nintendo told Kotaku in an email. “This emulator illegally circumvents Nintendo’s protection measures and runs illegal copies of games. Using illegal emulators or illegal copies of games harms development and ultimately stifles innovation. Nintendo respects the intellectual property rights of other companies, and in turn expects others to do the same.”


While the company has rarely looked the other way when it comes to piracy of its games and the tools that could facilitate it (like mod chips sold online), Nintendo has been particularly aggressive lately in clamping down on leaks and what it believes to be illegal misuses of its games and technology. In February it subpoenaed Discord for the personal information of someone suspected of leaking the official The Legend of Zelda: Tears of the Kingdom art book. In April it issued multiple copyright strikes against dozens of popular Breath of the Wild gameplay videos on YouTube that relied on modded versions of the game. And in May it seemingly had a Switch emulation tool, Lotpick, removed from Github after illicit copies of Tears of the Kingdom began spreading like wildfire online prior to the game’s official release.

It’s not yet clear how Dolphin’s current developers will respond, or how willing Valve will be to bring the store page back unless the matter is resolved in court, which could take years. Last year, Valve accidentally included the Switch emulator Yuzu in its YouTube trailer for the Steam Deck. The video was later edited and re-uploaded to remove the reference. The company did not immediately respond to a request for comment.
