Here is Volume 1 of "Mega World" magazine. This is a small magazine / booklet thing supposedly produced or helped by Sega in Japan. You can't read any of the text in that black area there, it's all in Japanese. The art is kind of confusing with Sonic holding a helmet he could never wear, standing in or possibly behind (but then it's really small?) a red convertible type car. What exactly is this "Mega World" about?
