My friend spoonman has a Super Magic Drive that he picked up on ebay. The Super Magic Drive is a game copier that will dump ROMs to a floppy drive or a PC connected via a parallel port. The one he got did not include the floppy drive so he asked me to make an adapter to connect a standard PC floppy to the Super Magic Drive. I put it in a NES case and used a blue LED to make it awesome.
I used the following information he had gotten from a forum years ago. I cannot credit the source:
