Yes there has been region locked peripherals in the past one example being snes controllers an American snes controller works in a American snes and a Japanese super Famicom but not in a European Snes just as a super Famicom controller works on a American snes but not a euro snes. Now here is the strange thing a euro snes controller works on all the regions lol.
Hmm apparently the euro controller had an extra resistor in it and to get American or Japanese controllers to work on the euro snes you had to add the resistor.
I've got a selection of Jap, Eur, and NA SNES/SFC controllers and I've never had a problem with mix-and-matching them between my Eur and US SNES's.
Thats because they must have been made after the Snes came out in Europe so they will have the extra resistor built in already.
That makes sense. My US SNES is the Jr/Mini, so the controllers that came with that would obviously be more recent than my release day EUR SNES.
On the gcn cables of controllers,but is the same for the gba cable to connect gcn to it?
The GBA-GC cables do have things in them, I have some pictures
