Any chance of doing any of the mattel handheld sports games? Also Coleco Electronic Quarterback was a good one too, would love to see those added to your excellent collection!
and my ultimate request would be for the game "Cosmo Fighter" by Casio. My dad brought this back from Japan and it was awesome !
there were a couple of other in this lineup that were especially good. Another one was "Astro Chicken"
