I finished up all Sega CD back inserts for jewel cases, and also scanned the digipack game cases, and the front/back of all of the original cardboard releases.
I also noticed that I never scanned the newspapers that came with the Sherlock Holmes games when I originally scanned their manuals, so I scanned in both of those and uploaded them.
So, that should wrap up a complete archive of US Sega CD art (covers, manuals, inserts, maps (for Vay), and supplemental books (the newspapers for the Sherlock Holmes games).
That adds to the also complete archives of US Sega Saturn and US Sega Dreamcast. I've got one Sega Master System game left to eventually pick up to also cross that collection scan off my list, then waiting for deals on 3 32X manuals to also cross those scans off.
As always, if anyone notices anything I missed or screwed up scanning, let me know.
