"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."
It really depends on the kind of encryption being used. I’m pretty sure if it’s a common algorithm that logic does not stand.
