"NEW: Nintendo is suing the creators of popular Switch emulator Yuzu, saying their tech illegally circumvents Nintendo's software encryption and facilitates piracy.
Seeks damages for alleged violations and a shutdown of the emulator.
Notes 1 million copies of Tears of the Kingdom downloaded prior to game's release; says Yuzu's Patreon support doubled during that time. Basically arguing that that is proof that Yuzu's business model helps piracy flourish."
I don’t know if the two cases are equivalent, DeCSS included all code necessary to decrypt a copy protected DVD.
Yuzu does not include the necessary code to decrypt a Switch game. Users have to either “hack” their own Switch, or pirate the codes. What the users are doing is the illegal part here.
