I made this post independently, maybe i should have posted it here, i'll copy/paste:
Hi, i've been downloading some of these covers (which is an awesome idea) for some time. Anyways, some of them have still not been retouched, finished or edited.
In the case of retail vertical n64 it's all right, but still some covers seem to lack some color. banjo kazooie, cruisin' USA, diddy kong racing, DK 64, F Zero, paper mario star fox 64 and mario 64. I still haven't printed any of these, so maybe the color is not such an issue.
in snes retail vertical covers i have found some little flaws:
Castlevania IV: there are a lot of black marks in the background, like some imperfections were just covered with a black marker.
Megaman X: Still some marks of the scan show.
Megaman x3: Same problem, but less noticeable.
Street Fighter II turbo: the black marks on the background
Street Fighter II: The same
Sunset riders: lots of white spots on the back cover (well, i don't know if the retail was like that)
Super GAMEBOY: mismatch in the colors in the background. (the black color)
Super Metroid: background black color
Super punch out: needs a lot of fixing.
and that's all, sorry if i am being a little bit too picky checking these covers, besides those things you all have done a very nice work.
