I had one way back. Super WIld Card...or Super Magic Drive. Something like that. The games did split onto multiple floppies and when loaded, they loaded into a simm chip inside the unit, then played in the Snes just as if a cartridge was inserted. Neat little unit, but still, what he is/was asking is nuts. I paid $150 I think back then, and I still see them newly sold online for just about the same price...if not less.
