I picked this Game Boy Color up relatively cheap on eBay so I can relive my lost childhood and cope with my meager existence. It has been a long time since I held a GBC but I don't know if it feels right. The seller mentioned some "discoloration" but it seems like the battery cover is almost an entirely different shade than the rest of the brick which makes me think the case has been replaced. Can anyone identify whether this is fake or not?
