*[[PS3 Savedata]]
==Common terms used in this page==
*[[PS2 Savedata]]
'''<userid>''' The number assigned by the system to this user when his account was created (is a counter). Stored in [[XRegistry.sys]], e.g: '''00000001'''
*[[PS1 Savedata]]
 
*[[PSP Savedata]]
'''<SAVEDATA_DIRECTORY>''' Name of the folder where the savedata files are stored, composed by [[PARAM.SFO#TITLE_ID|TITLE_ID]] + some variable characters added by the game, e.g: '''BLES00001-nick01save01'''
{{File Formats}}<noinclude>[[Category:Main]]</noinclude>
 
'''<TITLE_ID>''' Name of the folder where the game was installed (different than the TITLE_ID in his PARAM.SFO that refers to the originall ID when the game was released years ago as a disc)
 
'''<virtual_memcard>''' The name you assigned to the card when it was created from the [[Memory Card Utility (PS/PS2)]] in XMB

===Copy Protection Flag===
The ones without "Copy Protection" can be copyed to an externall USB storage device (by pressing triangle over his icon in XMB with the option "copy" of the side menu)
 
[[PARAM.SFO#ATTRIBUTE_in_SaveData|Copy protection]] can be removed from a Game Save by changing a flag in the ATTRIBUTE of his PARAM.SFO. This can be done when PARAM.PFD doesnt contains the signature of PARAM.SFO (only a few old games)
 
===Games which are unprotected===
There are two types of possible protections:
 
*One possible encryption in the files generated by the game that is not mandatory and depends of the developers of the game.
 
*And other protection based on signatures stored in [[PARAM.PFD]] generated and managed by the system. This file supervises signatures of other files of the folder, the list of files supervised is not fixed and again... it depends of the developers of the game, but usually [[PARAM.SFO]] is inside this list
 
This allows modifications/cheats for some games wich files are not encrypted, and not supervised by [[PARAM.PFD]]
 
* MotorStorm (protected with CRC32 checksum)
* Call Of Duty 4 (hacked saves can be found on the internet)
* Battlefield: Bad Company
* Assassin's Creed
* Blazing Angels: Squadrons of WWII

==Minis Saved Games==
This format is inherited from PSP (is older than PS3), and later implemented in PSvita, the "Minis Saved Games" can be exported/imported between the 3 consoles. There is no conversion of the files between the 3 consoles.

===PS1 Classics Save Game in internall HDD===
Stored in slots inside a "PS1 virtual memory card" in PS3 format, games can use one slot or severall ones, each slot has a name that identifies it (the first one is at offset 0x64 inside virtual_memcard.VM1 // it snt 0x8A for .VM1 and 0x64 for .PSV?)
dev_hdd0
|--- savedata
      |--- vmc
          |--- virtual_memcard.VM1
 
===PS1 Classics Save Game in externall USB===
When exporting to a "standard" USB device the Save Games are converted to "slots" in PS3 format. The name of the exported file is the identifier of the slot when it was inside a virtual_memcard.VM1
 
dev_usb0
|--- PS3
      |--- EXPORT
          |--- PSV
                |--- virtual_memcard_slot_ID.PSV
 
===PS1 Classics Save Game in externall PSP===
To export to PSP first is needed to register the PSP as a remote play device (in PS3 settings menu), and activate the USB mode (in PSP XMB)
 
Then, from the [[Memory Card Utility (PS/PS2)]] you can browse the slots inside the virtual_memcards, by pressing triangle over an slot and selecting the option "copy" the PS3 gives two options, one is an icon of your PSP identifyed by his nick, by selecting the PSP icon the PS3 displays this message: ''"Do you want to convert this data for use with the PSP system and then copy it?. If you select [No] the data will be copied without being converted"''
 
You can continue your game from PSP to PS3 under differents game formats such as cso/iso and continue on PS3 after transfer of your savedata if the game share the same DiscID. See: [[Emulation]]

*When the game is installed in PS3 it contains a "SAVEDATA" folder stored with the rest of the game files, only used by the PS3 to generate Save Games in PSP format
 
*This "SAVEDATA" folder used as a source contains a PARAM.SFO (with CATEGORY "MS" memory stick, and his SAVEDATA_DIRECTORY where it will be installed when exported to PSP), an ICON0.PNG (in 80x80 pixels) and two virtual_memcard.VMP (with empty slots). All in PSP format, never updated, and not intended to store Save Games, only to export them

The original memory card for the PS1 is 128 kilobytes of non-volatile RAM. This is split into 16 blocks each
containing 8 kilobytes each. The very first block is is a header block used as a directory and file allocation table
leaving 15 blocks left over for data storage.
The data blocks contains the program data file name, block name, icon, and other critical information. The
PSX accesses the data via a "frame" method. Each block is split into 64 frames, each 128 bytes. The first frame (frame
0) is the file name, frames 1 to 3 contain the icon, (each frame of animation taking up one frame) leaving the rest of the
frames for save data.

This Number is created unique to the current game played. Meaning the first time a game is
saved on the card, every subsequent save has the same identifier, but it a new game is started from
the beginning, that will have a different identifier.
 
The identifier is a variation on the name of the game, for example FF7 will be FF7-S01, FF7-S02,....(last bytes are not used in this case, can be also filled with zero in other game)
It don't really matter.
 
With a PocketStation program, the product ID is a monochrome icon, a hyphen and the later part containing a "P".
 
Country code(2 bytes)+Product number(10 bytes)+Identifier(8 bytes)= '''File name'''. See also: [[http://www.ps3devwiki.com/wiki/Emulation#DiscID_explained DiscID]]
