I have a problem. When I get to the boss of Wily's castle part 3, where he is chasing you, the screen freezes right before the boss appears. Sometimes the music will keep playing, or the music will start looping incorrectly, but I can't move Megaman, and the screen stays frozen no matter what I do. Is this a common problem? it is only freezing at this exact spot. it worked fine the first time I fought the boss, but I couldn't beat him. I turned off the game and a few days later I have had this problem every other time I have gotten to this part. This sucks.
