I hate the music in Persona 1 PSP version, so I created some of my own and converted it to Atrac3 format which the game uses. Then I used WinISO to extract my own files in place of the original ones and created new ISO. But the ISO i created doesn't work in PPSSPP for some reason. I've noticed the ISO i created is way smaller size than the original. Dunno why. I've been thinking that's the reason why it doesn't work.
Anyone here have expertise to help me out? I thank you in advance.
