Nintendo Is Now [?] Going After YouTube Accounts Which Show Its Games Being Emulated

As Russ notes, this is the second strike from Nintendo on his channel. The first, it's worth pointing out, was related to his coverage of a device which allows you to dump Switch games to your computer

[My emphasis]
It should be noted, the only way to legally play an emulated game is to dump the files off a cart/cd/floppy/w.e that you personally own. Which makes this even more egregious, as the video is about a device that could be used for piracy, but is also one of the only ways to legally make a backup of your property.
