Early days? Those consoles shipped 12 years ago.

I was gonna correct you and then I realized 2013 was indeed 12 years ago.

I guess in my original comment when I said "modern" I just mean not the classics. Other than the latest Xbox and Playstation models, emulators for those lineages are quite mature. Even the Nintendo Switch (2017) has multiple really great emulators.

The point is it's easier to list out which consoles don't have emulators than it is to list out consoles that do. Other than nintendo, there are pretty few console-exclusive games nowadays
