Neisword problem – Phantasy Star Classics Review

I’ve been playing this game for a year and I have to say that I love this game. The only problem is that when I get to the last stage, whenever I use the neisword, the game freezes and I can’t do anything except for exiting out of it. It’s nothing serious I just want this glitch to end. If you could please fix this glitch I would be really appreciate it.
