回答“Theres a slot on the bottom of the console whats it for?”Like said above, it was a partnership with SONY to make a CD-ROM add-on, but Nintendo saw what happened to the Mega CD (/Sega CD) and got cold feet. This gave birth to the competitor they STILL fight yearly - SONY Playstation! (So it's a good thing it was never used really!) There's art of the proposed "SNES CD" and also ONE Prototype found in the wild! I think Ben Heck showed it off? Just look up "Nintendo Playstation Prototype" or similar.
