The Sega CD (Mega CD if you're not in the US) actually had (pretty much) the same graphics capabilities as the normal Genesis, so the opening video had to be adjusted in order to fit into the Genesis' limits. All the other versions had the normal one (2011 remake, SEGA PC version) but the Sega CD version is the only one to have this version of the opening. Anyways, I used https://ezgif.com/sprite-cutter to rip these (I mean, nobody would want to rip 717 frames of animation, right?) These were originally ripped by WizToad on The Spriter's Resource.
