I have Atari 5200, Atari 7800, Atari Jaguar, Atari Jaguar CD, Intellivision and Colecovision overlays in my artwork collection but I am not sure about the quality, hence I never said anything. I know your standards are quite high, which I agree with and I'm sure they wouldn't comply. I think it's get that we forget about the "junk" floating around and make new, uniform, clean, high res scans.
