so i finally fixed the graphics problem and now when i get to a certain point in the gain a cutsecne freezes in a continous loop where there is supposed to be more talking. i know others have made it through the whole game so im sure its just a configuration problem on my part.
Disable all speed hacks and set the EE and VU options back to default, then load from a memory card and try passing that spot again. If this still doesn't work, remake your ISO image from your dvd disc using imgburn
