Kingdom Hearts 358-2 Days

Is there anyway to fix this problem? I did missions 52,54 and 55 and it wont let me do 53... everytime i go to 53 the screen goes black but i still hear the music and everything. I tried other roms and the same thing happens

 

r4 :/

 

its still doing it, anybody else no how to fix it? I really wanna beat the game and i no im no where close.

or can somebody give me a save anywhere from mission 54-60... somewhere close to mission 53 but after it 54 if possible though :/
