"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."
Somebody correct me if I'm wrong, but I don't think Yuzu has any proprietary code. Folks have to go to other websites to download the Switch firmware and keys needed to play games.
