Space Harrier is such a fun & easy game to get into, at least if you're only trying to see the end of the game & not max out your score (why not do both?).
From what I've seen, SFZ looks a little choppier...perhaps choppier than Space Harrier II on the Mega Tripe? I dunno...I've somehow avoided CDRs so far, but I may have to make an exception for this game
