Drill Instructor

Greetings to everybody!
I've been so enthusiastic being able to play this marvellous game once more!
I just have some question: defeating the last of 5 wizards, I dueled the Drill Instructor (the last boss with 300 lives). The issue is: I can never end this combat! The game just stops because the enemy begin thinking to the next move over and over. I tried even to give him all the time he needed to think (I left my pc on overnight).
Is this a bug? How can I possibly overcome it?
Thanks everybody!
