I found a guide in the thread made when P3P was dumped, but I followed it and it didn't work. I extracted the umd0.cpk and umd1.cpk of both the Japanese and English versions and replaced all the files in the English data/sound/voice with those from the Japanese version. The game wouldn't start up. The companies' logos wouldn't show up. I tried exporting and importing the filelist, but there was a problem with positioning some files when I tried to save the ISO. Any ideas?
