So I was battling the lass on the route between Mt.Moon and Cerulean City near the berries, and she sent out a level 18 Paras. It used Fury Cutter on my level 13 Sandslash and then I used Rollout. The next turn Paras used Fury Cutter again but missed, then Sandslash continued with Rollout, hit, and the game crashed. I think the crash is related to the fact both Pokemon were using power-increasing moves when used in succession, and Paras missing Fury Cutter screwed up something.
