If you change the game id code in resident evil 2( SLUS-00421 ) for the japanese one (SLPS-01222) the game no longer locks up in the police station or other parts. In dino crisis if you change the id for its japanese one you get the sound back in cutscenes that was absent before.
I dont deserve any of the credit for this, because other people (Dany23 & graz68 ) found it first , im just posting it here for your benefit :)
