Kingdom hearts 358/2 days

Ok I'm not sure if this happen to anyone by this time. First of all I have an acekard 2i on a ds lite. Akaio 1.5 with updated loader. Now I've been playing KH for a few days now and I'm on day 74. After fighting the big lizard thing it goes into a cut scene where roxas picks up xion after getting knock. Roxas, Axel and xion suppose to go somewhere so as they run off it goes to a black screen and stays there. No sound or anything. How do I fix it. Also the rom is from this site

You could try updating to 1.5.1
