ok so i downloaded black chocobo and i wanted to just make my save file have clouds final omnislash attack.. but when i went to save the file then said "it didnt have the updated checksum and wont play on psp". i was wondering is there a way to fix this so i can play it on my psp? also i was wondering if since i cant do the gamesave tweek, someone else can get my save file and do it for me and give it back. i would rather want to know how to fix the whole checksum but at this moment anything is good enough
