Can play Genesis/CD/32X games and you don't need the CD or 32X unit to play them. I would imagine this is a good buy for some people since Sega CDs are netorious for breaking down. Also would be a good way to play those Sega CD games like Snatcher, Cobra, or Lunar etc on actual hardware instead of paying the hundreds of dollars it would take to get legit copies.
Have any interest Jerry? Might pick this one up instead of the Genesis Mini Deathadder?
