If I'm not mistaken, those scans in the Geibunsha category belongs to JohnnyD/JapaneseMagazineScan from Retromags, who has done a excellent job scanning his Neo Geo Freak issues, as well as his Gamest and Arcadia issuesThose have been up on the Internet Archive for a long while now, and there’s more than just those if you search for “Neo Geo Freak” on there. Also, Geibunsha is the original publisher of the magazine, they didn’t scan them and upload them themselves, someone did so using their name.
God bless JhonnyD of RetroMags for his endeavorThe Last 2 books as been posted, we have the neogeo freak completed.
