Most of the animations that I've done to date are scanned from prints made with the Gameboy Printer (with new, non-lick backing). Recently, though, I've been scanning the screen. It takes longer, but the result is a crispier image. The paper for the printer isn't cheap, so it's a money-saver too.
Shooting with "trick lens #9" you can get four images per "frame", 120 images per batch. I'd like to have a Gameboy Camera project on SITO. What do you think? A movie? Day-in-the-life-of-SITO with GB Cams?
