> Emulators are legal, including emulators for current-gen systems. Switch emulation is exactly as legal as Gameboy emulation.
I know you're talking about emulators, not ROMs. But it's also worth mentioning that the legality of Switch ROMs actually is quite different from Game Boy ROMs. I was recently surprised to discover archive.org has ROMs for older systems - IANAL, but apparently this is covered by a DMCA exemption for obsolete formats [1]. Also, Switch ROMs are encrypted on the cartridge, and while I really don't know the details, breaking the encryption also seems to open another legal can of worms (remember when people would get tattoos of the DVD encryption key?).
Once again IANAL, but I suspect Nintendo would have a better case against videos that include instructions on acquiring & decrypting Switch ROMs. I'm not sure if that's the case with these videos or not.
