These little machines were pretty much a last ditch effort by Sega to compete with Super Nintendo. It's pretty much a mixture of a Sega Genesis and a Sega CD. Now, don't get me wrong, that does'nt make this is a bad system at all, in fact it's just the polar opposite, this thing is amazing. The only gripe is the fact that the cartridge input is on the back, which in turn, makes putting a Sega 32X on this thing really hard. The designers (for some reason) didn't really think about using a 32X on the CDX, and because the 32X is kinda heavy (In comparison to a Sega Cartidge), and because the cartidge input is in the back, it makes the CDX fall backwards. Not only that, but you can't open the disk tray while the 32X is attached, making it a pain. But since 32X's are really bad, you don't need to worry about getting one. Another cool feature I like about the CDX is the fact that it can be used as a portable CD player, but if you're smart you wouldn't be foolish enough to do so, as these are rare as ever. If you can find one at an affordable price, get it, but if not, just forget it. An all-around awesome console.
