If Seeker tries to open the wrong elevator door up on the maglev ledge, in DOSBox he will try briefly and then give up. In ScummVM, the animation just keeps repeating. (And he even manages to get the door open, however briefly, before it snaps shut again.)
That animation has been added because the behavior looked wrong without it, giving the feeling an animation was missing. I'll check with and without our modification and see...
It doesn't look wrong in DOSBox, though. Seeker tries to open the door. It may budge ever so slightly (it's hard to tell, because he's standing in the way), and then he gives up. In ScummVM, the door keeps opening and closing like a high-speed accordion.
Oddly enough, if Quinn tries to open the door in the original game, he doesn't give up either. (For a while, I thought the solution was to have both of them try at the same time.) But the door stays firmly shut.
