Editing Game Saves

==Saved Games==
These files are stored on the PS3 HDD, and can be copied over to a media through USB or similar. There are two types, those which are encrypted+signed, and those which aren't neither. This allows modifications/cheats for some games, yes. When copied, they are put inside these folder called "PS3\SAVEDATA\", followed by their Title ID. I'd like to call the encrypted+signed saves as protected saves.

==Save Game Directory Name Format==
All games define their own sub folder(s) based on the following pattern
based in on information from PS3 Secrets, thanks

standard pattern parts: ABCDEF
A==> Media Format B=Bluray, S=Dvd
B==> C= First Party , L= licenced
C==> Country code A=Asia , E=Europe , J=Japan , U= US
D==> D= Demo, S= game , M=?
E==> Unique 5 digit game Start ID
F==> Unique Game Creaters define the remainder of the format

==Directory Structure==
{| border="1" cellspacing="0" cellpadding="5" border="#999" class="wikitable" style="border:1px solid #999; border-collapse: collapse;" 
|- bgcolor="#cccccc"
