Nintendo historically has been a company that never really practiced backwards compatibility on their major consoles. They did it on the Wii-U and that's about it I believe. Think they've just conditioned folks to accept it and keep it moving
you could put a game cube disk in the Wii. Think it might have had VC as well. I think at most for each system the made you could go back 1 gen with no issue. even with the DS and Gameboy? At the bottom, one handheld had a slot for the top and bottom of it can't remember which one tho.
