I've been wanting to play games like Star Ocean 1 and 2 and Valkyrie Profile, but I cannot get them to play for the life of me. These games play fine for the first 10 or fifteen minutes, but very often a text bubble will appear without any text, and the PSP freezes and shuts down. I think it might be because the game can't load the voice file or something, because voiceless games like FF4 Complete work perfectly. And physical games work perfectly, too. Using a 2000, CFW 6.60 PRO-C2. These problems always occur with M33 Driver. But whenever I try to use Inferno or SONY N9660, games won't load at all and the PSP just shuts down. Is there any way to fix this problem? EDIT: Another game that failed to work correctly was Crisis Core. The problem occurred in cutscenes with voice acting.
