Looks good, some seem to use lower quality scores.
Some of these covers already exist in the forums, such as Donkey Kong (GB), I made one a few days ago from higher quality resources.
Others we could use, I need a Spy VS. Spy cover. If you are in to making Game Boy covers I made a newer template, It is for 3DS cases but all I ahve to do is thicken the spine for it to be used in DS cases.
