I have had this for a little while now. I bought it from someone on here a long time ago and never really used it that much. I don't have an extra AC adapter for it but it takes a Genesis 2 adapter. I only have one AC adapter for my Genesis. I am only asking $40 plus shipping. I would trade it for Demon's Crest or Gargoyles Quest 2 for NES. I have hooked it back up and it does work. I don't even have any floppy discs laying around but I am sure it works fine. It can load Genesis or SNES games. PM me if you want it.
