Me too, even moreso given the fact based on interrupt timing alone, Conker's BFD either runs through the legal screen with polygon storms, runs through the legal screen without polygon storms but without Conker in it and then crashes a few frames after the Cock & Plucker Inn appears, or crashes sometime in the Inn itself.
