I see your pumping out these Saturn covers pretty quick. I was looking through some of the covers you just recently uploaded and Im noticing a good ammount of dust that could be cleaned up. I only checked out Ghen War, Dark Legend and Skeleton Warrior but they all had a decent ammount of dust that could be cleaned. Might even wanna run a sharpen filter on them.
Keep the covers comming but I would put a little more effort into removing all the dust from them before you uplaod them. 
That's after some serious cleaning. Don't think that I'm making 15 minute covers, I've actually started working on these a wile ago.
Unfortunately the source material is not in great shape. I think the first step everyone should take before they scan something is clean the glass.
I'm sure you're talking about my scans and you hit the nail on the head. All the Saturn scans currently in the raws section uploaded by me were the first ones I did for the site (besides a test Genesis game). I not only didn't think to wipe the glass off back then but also didn't lightly wipe off the cover itself (like I try to do now).
This batch of Saturn covers should be night and day better. If you want me to, I'll "box.net" all or any of these you want now (I'm putting the list of the ones I have ready so they won't be duplicate requested for
tsolfan to scan).
