I agree with you but with an exception of different result. I managed to duplicate two files, rename the save folder (internally) using SFO editor and the folder name.. using SFO editor and later resigned it with Exploder. It seems to work, it doesn't overwrite my save file but I cannot load two save files at the same time as two different characters It means, that PS3 cannot tell the difference that they are two different characters even after the renamed/resigned.
It's probably both save files' names remained the same. There is two different SFO editor. I also using the SFO editor from aldostools.org (from PS3 Tools).
