The thing that changed in the ROM was like in the prologue, when Fado is talking, his face was glitched and half of it would disappear and blink back over and over. I am completely sure I am patching it correctly, I have the Japanese ROM, the IPS patch in the same name, and both are in the same file. Hard patching makes the faces glitch, and auto patching doesn't do anything.
Edit: I also already extracted it, just to save time.
