Hey There CAG's I have come here for your expert advice today. I picked this copy of Pac Man 2 for the genesis up at a flea market last week. I know they made a cardbox box version and a regular hard plastic case version of the game but I've never seen this lenticular cover before. I tried searching both ebay and google for info on it but came up empty handed. Does anyone know anything about this thing or possibly what it's worth?
