Well setting aside all the morality questions, I’m with @WarpRattler in being shocked this hasn’t been shut down. When people are making emulators because they want to make emulators, it doesn’t surprise me that they don’t get stamped out more often, but when someone’s pulling in big bucks via Patreon, you’d think Nintendo would at least have the clout to get that Patreon account shut down.
And of course maybe they do, and that will happen in a week or so now that this is getting publicity.
