It does not allow for connection to Sega CD, Powerbase Converter (master system conversion kit for the the Genesis 1&2) or the 32X.Overall, this system is pretty darn good if you are a Sega fanboy like myself, and I have been playing lots of NHL 97 on it since I got my own machine a little over a week ago as of this writing.

Plays just as well as the original Sega genesis

The shipping box said sega genesis classic but the product was an Atari

Packed with 66 great original Sega games (with 19 bonus games from AtGames), instead of only 21 games, including the lame and over-hyped gimmick

The Sega 6-pak did not work

It comes loaded with 85 games and there are lots of familiar favorites like Altered Beast, Golden Axe 1 & 2, Shinobi III, Mortal Kombat and the Sonic the Hedgehog series and others including a few first generation Sega Master System and Game Gear games.
