Kingdom Hearts 358/2 Glitch with prepatched.

I was starting Kingdom Hearts 358/2 days, on a dsi with an R4i, and at day 7, when Roxas gets up, a black screen shows up, and continuously makes a sound. Please help. (I had gotten this rom from the megaupload link on the fourms which had the prepatched rom. I was playing this on story mode, beginner)
