Guys I had issues with this but I can confirm this is the best mule out there. I am EU from Germany and I had to do zero modification with bruteforce or anything.
All items all lvl 1 chars no freezes corrupts or any modification needed.
If you are having issues check that the USB flash drive is empty. I used my mp3 player and ps3 had issues with it. Use a run of the mill empty drive. Also delete your previous savegame it will conflict with the mule.
Follow what people said.
Make a folder called PS3 in that folder make another called SAVEDATA extract mule in there.
On you ps3 go to your game utility folder and delete your old save then copy this one.
Good luck people!
