ahh, I see. .so that's why it showed corrupt file. .at least from my experience viewing other threads and trying the SFO editor out, its not 100% that you would be able to change regions and make it work on your PS3(at least for me). .I still say Xploder is better at changing regions(I'm just going to say in advance that I don't have an Xploder). .Have you tried it again by changing it to another region, then changing it back, put it back in your PS3 and see if you can still load your save file?
