Europe got the Multi-Mega and the US got the Sega CDX and everything was nice and tidy with Sega's hybrid console. Sadly this boxed Sega CDX auction doesn't help mix things up with being only available to buyers within the US, but it's a pretty impressive offer nonetheless. The rare CDX comes complete in its box (with games, cardboard bits, manuals and everything) and seems to be in excellent condition.
Oh, and you may need to be reminded that the CDX is the handy combination of a Sega Genesis and a Sega CD in one handy console. It's even compatible with the 32X.
