Price negotiations are available for customers who have liked the item! This is a listing for a SEGA Mega Drive & Mega CD 2 set, models HAA-2510/HAA2912. I have confirmed that it works with both CD and cartridge versions of the games I own. The joint parts are missing, but this does not affect gameplay. There are some scratches and dirt as it is an old item. This is a very valuable and advantageous set, so please be aware of potential sell-out!
