According to an official statement on Ryujinx’s Discord server, developer gdkchan was contacted by Nintendo and they were offered an agreement to stop working on the emulator project, and while the agreement wasn’t confirmed yet, the organization has been entirely removed.
Nintendo’s real intent is doubtless to try and ensure that nobody ever makes a functional emulator for the upcoming Switch 2.
Good fucking luck, the hardware will likely be a 2022 tablet if the switch is anything to go off of. Considering as well the console will likely have similar architecture, and switch emulators already exist, I’d give it about 3 months.
