*[[PS1 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'''
*[[PSP Savedata]]

**'''<virtual_memcard>''' The name you assigned to the card when it was created from the "Memory Card Utility (PS/PS2)" in XMB
**'''Any_Other_Files''' Represents all the other files in the folder generated by the game with any filename and filextensions that are dependant of each game and can vary, e.g: "PROFILE.BIN", "PROGRESS.SAV" (in PS3 Game Saves) or "SECURE.BIN" (in Minis Game Saves) etc...
**'''<MC_Save_ID>''' Identifyer of each Game Save of a PS1 or PS2 Memory Card. Used as the file name when an single Game Save is exported to USB, e.g: '''BESLES-53702535953'''.PSV
**[[PARAM.SFO]] Information about the Game Save. This one is never encrypted.
**[[PARAM.PFD]] Signatures of some of the other files in the folder. The signature method is still unknown.

===PS3 Copy Protection Flag===
The ones without "Copy Protection" can be copyed to an external 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)
 
===PS3 Games 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

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.

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.

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".

====Virtual Memory Card PS1 (.VM1)====
VM1 is a PS1 memory card in "PS3 format", used in PS3 internal HDD only., games can use one block or several ones, each block 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?)
 
====PS1 Single Save ? (.PSV)====
PSV is a PS1 "block" in "PS3 format". When exporting to a "standard" USB device the Game Saves are converted to "blocks" in PS3 format. The name of the exported file is the identifyer of the block
 
Size: 9KB (only one single save data using one block)

====Virtual Memory Card PSP (.VMP)====
VMP is a PS1 memory card in "PSP format"
 
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 blocks inside the virtual_memcards, by pressing triangle over a block 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"''
 
If you select [YES]:
Then, PS3 will display the others virtual memory cards of your PSP (SCEVMC0.VMP and SCEVMC1.VMP for each ps1 classic game) you select where to copy the save data. It s doesn t really matter which virtual memory card was selected, you can import/export internally on PSP after.
 
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 and . See: [[Emulation]] and '''Filename''' ( on following structures, and Identifier doesnt really matter  )
 
 
*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.
 
Difference between SCEVMC0.VMP & SCEVMC1.VMP when copy to PSP: the slot 1 is for SCEVMC0, slot 2 is for SCEVMC1.VMP. If you save previoulsy on slot 1, it will be SCEVMC0.VMP who contain the informations about your savedata.
 
*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 blocks). All in PSP format, never updated, and not intended to store Save Games, only to export them
 
Size: 129KB ( on PSP, size displayed is different)

===Memory Card Formats PS2===
 
====Memory card PS2 (original)====
The PS2 memory card file system has a fairly simple design, with some allowances made for the limitations of flash memory. It's overall structure is similar to the well known MS-DOS FAT file system. It uses a file allocation table (FAT) to keep track of allocated space and a hierarchical directory system where all of a file's metadata is stored in it's directory entry. Like the FAT file system, which groups disk sectors into clusters, the PS2 memory card file system groups flash memory pages in to clusters. On standard PS2 memory cards, the cluster size 1024 bytes, or 2 pages long.
 
*The Superblock
The key to the PS2 memory card file system is the superblock. Located in the first page of the memory, this is the only part of the file system with a fixed location. While some things like the do end up in fixed locations on standard 8M memory cards, you shouldn't rely on this.

====Virtual Memory Card PS2 (.VM2)====
The file begins the same than a "original PS2 memory card". Its not verifyed if there is something added at then end etc...
 
====PS2 Single Save ? (.PSV)====
 
====Virtual Memory Card Exported? (.VME)====
Virtual Memory Card in "E" format ?
 
When exporting Game Saves for "PS2 classics" (CATEGORY 2P) to a external USB drive there is a "rare" PARAM.SFO exported. This PARAM.SFO seems to be a copy of the main PARAM.SFO from the installed game folder with an added "signature" "injected" at the end of the file (out of his structure) with a lenght of 20 bytes. Is supposed to be a security feature when exporting the gamesave, is not confirmed if this PARAM.SFO (with the injected "signature" out of his structure) exists in the internal HDD (when importing, or present at some time with the "PS2 virtual memory cards").
