You mean, make a savestate and attach it to the post for investigation? Or to try reloading many times until I manage to pass the bugged part (in case if it's possible to avoid issue that way)?
Upd: ok, I check original usa version of the game and it worked fine. The one I played and it froze after last movie is undub version (pretty much the only reason why I played psp version; I played psxone before but I wanted to see undub version too which doesn't exist for psx). Well, I guess this issue won't be checked for many reasons so I'll just leave this note. But if someone would like to check it, I can provide necessary data.
