hi all I was wondering if some1 had a good .cpk extractor that could build again the file once u have hacked it. In this topic I was wondering how to replace music in P3P (Persona 3 Portable) putting music of P4 (Persona 4) for ps2. There is a video on youtube of some1 that did it but he doesn't answer me and his videos are 3 years old so I don't think he will anytime soon . Can some1 explain how to do it and give me tools needed for it to be done?? ty a lot
