A CD-based peripheral for the SEGA Genesis. For the time, it was pretty innovative, but sometimes even innovation sucks, as evidenced by the Atari 5200. First of all, it had its own AC adapter, so that's two, and chances are, you probably know what a nightmare that is. The load time on that thing was rivaled only by the Commodore 64, and most of the games on that thing were more like watching movies than playing games. As far to my knowledge, there were only a few good games, The Terminator, Dragon's Lair, Snatcher, Batman Returns, Penn and Teller: Smoke and Mirrors, and the one that almost everyone knows, Sonic CD. By the way, this papercraft is compatible with both versions of my SEGA Genesis papercraft. Enjoy those and this.
