>Is there any sort of production year on that NES controller your friend found?
I'm holding it right now, and the answer is no. There's no text anywhere in the plastic and it came with no instructions.
>it seemed to use a radio frequency to work
I was about to ask about exactly that. That's pretty much what I wanted to know, since it's obviously not Bluetooth I was afraid it may be infrared. I've read only negative things about infrared controllers, vid related. They're basically remote controls.
The story of why I have one: Santiago, Chile. 2015.
My mate was walking down the street and found one on some old toy store. Went in and asked if they had just the one in the window, because he wanted at least two. The clerk told him they had a bunch and my friend asked how many they had in stock. Apparently they had like 40 units.
So my friends offered to buy them all for a ridiculous amount, expecting a negotiation, and the guy just said yes. So he went home with a load of these controllers for about $22 American dollars.
He saved a couple for himself, saved one for me, and sold the rest to retro hipsterinos. I think he sold them all, but I'm not sure. I'll ask him tomorrow because after I test mine I may want another (I'll have to pay for that one, though).
Anyway, given that the only possibilities are infrared, RF and Bluetooth, I'm happy about it being RF. That falls right in the middle on the scale of acceptable wireless performance.
