Of all the other artwork, working on the logos for the USA Genesis releases was the most troublesome part. There were lots of wheels/logos mismatching their cover arts, some were found already cut, others I did myself.
It has all content released in USA, including official, unlicensed, protos and compilations. World unlicensed games like Xeno Crisis and others aren't included and will have their own pack later, some extra carts were made to fill in the new additions.
Includes 22 titles released on the Sega Channel service, which are exclusives, even some undumped and titles that were only available physically in Europe and Japan.
Early prototypes which are mostly broken/incomplete weren't considered, while the most complete ones were already tested and added on previous efforts.
