Found this on Ebay for like eight bucks. It's like one of those interchangeable LCD things except it actually has a dot matrix display. The "CDs" are actually just pieces of plastic with little protrusions on them that select the different games (which are all built in.) The one I have has three games, Hockey, Soccer, and Auto racing. The games actually have music and sound effects. The racing game was had behind the car perspective and came off pretty good but the other two were kind of boring. Games are like the games you find on those "game watches," fun for a little while but really nothing special.
