Rockman Hoshi ni Negai wo

Not fitting the new style anymore, it never was included in the series. Still, two more episodes about the same story were produced a bit later, this time under the main title "Rockman" (unlike episode 2, where he's called "Mega Man" even in the Japanese dub). It's unknown if these 3 episodes ever saw an official release, until 2002, when Capcom of Japan decided to finally release them on DVD for Rockman's 15th Anniversary, all featuring a Japanese and English dub, but no subtitles. It's unknown if there are any more secret animated works of the original Rockman game series.
