To view these DEMOS on the SNES you must have an MGH or Magicom which allows the connection of a 3.5 inch floppy drive and a front end OS to your SNES which allows to load software without using a cartridge. Many peopole use them for illegal purposes, but more creative people are now writing software for the SNES, and some of the demos look right tasty! I reccommend getting an MGH or Magicom if you are into programming as well, I hear programming for the SNES is a little tough though.... good luck!
