Since I've discover this through a tumblr post, there's interesting stuff of RKA in the issues released in 1993. Stuff seen in the magazine is screenshots or artworks never before seen. I might update this blog if I find more RKA related content within the magazines. Credit to the user(s) from SegaRetro who were able to get these! Tools I used for are SmallPDF, to extract the pages, and Online-Convert to convert them to PNGs.
