Background

I'd always had the project in the back of my mind after seeing an old Usenet post from Kevin Horton about running a 2600 on batteries, but got even more enthused after Ben Heckendorn build his first model. However I wanted to make mine as small as possible and use an existing controller shell to keep things easy, but still looking good (I'm horrible at working materials). The first plan was to combine a TV-boy (the handheld Atari clone) with an lcd tv in some fashion. After that, thought about placing the 2600 guts into a playstation controller, but that didn't have any area to surround the TV screen. Then one night (while washing dishes strangely enough) it hit me to use a dreamcast controller, with the lcd placed in the VMU area.
