But there is no home button on Nintendo's first-party NES or SNES-style controllers, which I think are the ones more directly comparable to what we're talking about here.

(Not sure about the N64-style controllers; I've never actually seen one of those in the wild)

It looks like the N64 controller has a Home button [1], as does the Genesis [2] controller. Which makes it even more curiouser that the NES and SNES controllers don't. :(

Personally, I count the NES controllers as Joy-Cons, since they slot into the side of the system, as other Joy-Cons do. They don't fit in my Joy-Con charging dock or the Joy-Con grip that came with the system, though.
