Portable devices (GB-GBA, DS, PSP, etc.) should be easily scanned with a regular scanner. The bigger stuff would require a large scanner or multiple scans. But I don't see the need to scan the covers for the consoles. I mean, if you really want to store your handheld devices in a UGC, then I guess I can understand that. But there's no real means of storage for the consoles that's universally accepted (and by universally, I mean here on this board.)
If other people are on board for this though, I do have my Lime Green Gameboy Color and Black DSi boxes I can scan.
