Im fairly sure I beat TMNT: The Arcade Game. But I got STUMPED on the other TMNT game for NES. I don't know if anyone remembers it well, but there is this one level with the Ninja-mobile (turtle mobile? I cant remember what it was called... the van) and you have rockets to blast through different gates that block off this maze... anyways, there is a part in the maze where you have to clear a massive gap between two buildings and you need a rope to do it. I never did find that rope; I wouldn't even be surprised if my game was busted and just had no rope, haha. Anyways, because of the Rope being missing I never passed that game.
