I looked around and couldn't find anyone posting or talking about this, so maybe I just didn't search enough. But it seems that the Mega Man Ruby Spears cartoon sales pitch was genuinely found on its original VHS format just about two weeks ago, and Protodude over at the Rockman Corner
did a digital restoration to make it as clear as possible. Four more years and maybe this would've actually remained this way rather than get screwed by focus groups and the western animation trends of the time..
(Amusingly the tape comes with two promotion commercials for The Wily Wars and Mega Man V for the Game Boy. Apparently ol' Rock didn't even have a jumping animation in Wily Wars at the time.
