A Super Nintendo (SNES) Floppy drive?! How does it WORK?

Before we had modded playstations and pc emulation it was almost impossible to make quality bootleg copies of the games we loved. Back then you either bought the games which was expensive, especially for a child or rented the games which always left me wanting much more.. We where stuck with no easy way to copy them. Or at least I thought this was the case until I discovered this awesome system adapter which allows gamers to play snes games off of floppy disks. Now we have emulation so it is nothing more than a neat collectable but I would have given my left ear to have this as a child!!
