What about the Colorvision system? I know it's a blob, the board can be seen at the bottom of the page here: http://www.handheldmuseum.com/Romtec/Colorvision.htm They only made 5 games for it, and they are all programmed on the chip in the console itself, so it's only one chip to get the entire system (although we'd need to scan the LCDs...) Just curious if anyone has looked into yet. It's a rare system, so not one we'd want to have to sacrifice several times..
