The Sega Multi-Mega (or the Sega CDX in North America) was a 16-bit video game console released in 1994, combining the Sega Mega Drive (Sega Genesis in North America) and one of its add-ons, the Sega Mega-CD (Sega CD in North America), into a single compact unit as a final attempt by Sega to encourage consumer interest in its fledgling Mega-CD format. It was sold under the name Multi-Mega in Europe (350 GBP or 999 DM), Genesis CDX in North .

User Reviews about Sega CDX - Video Game Console

This system is an absolute no-brainer for those that still absolutely love Genesis and Sega CD games. It's a small combo system that only uses one AC adapter, which means that it hardly takes up any space at all - A plus for anyone who likes to keep multiple systems hooked up.

However, the catch with this system is that it makes the most sense to be into the Sega CD's paultry library, which isn't particularly small, but isn't drowning in great games either. The great games that the Sega CD offers are also rather niche, and not for everyone. I bring this up because it doesnt make much sense to "overspend" on the CDX if you hate the Sega CD portion of it - You can just pick up the Genesis at a fraction of the cost and pick amongst the Genesis'robust library.

This really is a wonderful and practical little system that makes the most sense for gamers that really love Genesis and Sega CD games. Well, I guess this makes sense for collectors too since it isnt the most common old-school machine around. Just makes sure that you REALLY still love this generation of games, and do a little research into the Sega CD library, before you throw money at it. -- Practical System for Genesis and Sega CD lovers

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. -- Grab one if you can find it at an affordable price

Most video game aficionados will tell you that it's important to not only remember the roots of home video game consoles, but to own a few of them as well. There is no better way to play Sega CD games and Sega cartridge-based games than on this little unit.
I have owned mine for (gasp) 12 years, it's taken the licking and keeps on ticking.

This has to be one of the smallest gaming consoles I have ever owned. The Sega CDX is roughly the same size as the Heroes - Season One box set. For the folks that want to save game progress, you'll be pleased to know this is compatible with the Sega CD Back Up Ram Cart, and will even allow you to play music CD's. All your old Sega cartridges should work on it, and it also has a headphone jack, similar to the one on the Genesis system.

Now for the drawbacks.

First and foremost, the Sega CD games and the cartridge games are not easy to come by. You'll have to either search around in Amazon or eBay to find the best games for your collection, or find a video game retailer that specializes in older systems.

Secondly, the Sega CD games are not all that great. They get extremely repetitive after a while, and most of the games were created to show the player that Sega was the first system to support full motion video - but all this amounts to is 16-bit gameplay intermixed with a lot of grainy video footage. To be honest, some of the rarer games provide a lot of laughs, such as Supreme Warrior or the game that caused the creation of the ESRB, Night Trap (Unrated Version).

Also, there is also some debate as to whether or not this system is compatible with the Sega 32X Unit. Apparently the 32X has metal prongs that need to be inserted into the cartridge interface for the 32X cartridges or the 32X Sega CD games to work. I'm not sure about you, but I don't feel safe putting metal into a video game system...that sounds a little too much like putting a paper clip into a light socket. With my luck, this would probably lead to the unit getting damaged beyond repair, with no retailer to fix it. I'll leave that choice up to you.

Since this unit takes up considerably less space than the original Sega console with the Sega CD add-on, I can highly recommend it to anyone who wants to take a trip down memory lane, back when Sonic the Hedgehog was king of the consoles. Enjoy!
