Ok, when I try to go into the World Trade Center in Jubelife City and entering the door after saving the game, my screen turns black and the music makes a frozen humming sound (sorry. I can't describe it well enough). This problem occurs when I have my softreset turned on and off. Also this is on the latest M3 firmware. Please, oh please help me with my problem and thanks in advance. EDIT: I am using M3 Real and also what is a clean dump rom?
