Kingdom hearts birth by sleep

Hey i just modded my first psp 2000. It is running cfw 6.60 pro-b9 and i downloaded khbbs here frok a trusted console uploader wakefield. I put the game in my memory stick root in a folder named ISO then start my psp go to game on xmb and start the game it plays but when i start right after the duel and you have to save for the first time it freezes. I changed vsh to m33 and sony driver still freezes. Is it the game or is it on my side? Please help thanks
Answer #1
It’s most likely the game. It may have been patched wrong or got corrupted somehow.
Answer #2
Yea i think the game got corrupted, redownloaded works like a charm
