===PS3 Protections===
There are 3 possible protections in "PS3 Game Saves" that can be used together at the same time, it depends of the game wich ones are used and what files are affected
 
====PS3 Game Save files encrypted====
Game developers have the option to encrypt the files generated by the game (when the game writes/reads the Game Save). This encryption/decryption is managed by the game and is different for each game, in some games this encryption doesn't exist, this allows modifications/cheats for Game Saves which files are not encrypted or the encryption method is known, and are not signed by PS3 (read next section below)
 
For more info about unencrypted game saves see: [[Game_Modding]]
 
====PS3 Game Save files signed====
PS3 can generate a signature for each file inside the folder, this signatures are stored in the [[PARAM.PFD#Protected_files_table | Protected files table ]] inside the file PARAM.PFD
 
This table inside PARAM.PFD is limited to a maximun of 114 signatures, seems to be a number high enough for all games developers to protect all, but the fact is usually only a few files (the important ones) are protected with this signatures, one of them uses to be PARAM.SFO
 
This signature generation/verification is managed by the PS3 and not the game, and can be used together in combination with the previous method (1ºencrypted + 2ºsigned)
 
====PS3 Game Saves Copy Protected====
There is a "feature" in "PS3 Game Save" format that allows developers to disable the "copy" function to an external USB storage device (by pressing triangle over his icon in XMB with the option "copy" of the side menu)
 
This "copy protection" is managed by a "flag" that can be turned on/off inside PARAM.SFO, see: [[PARAM.SFO#ATTRIBUTE_in_SaveData|Copy protection]]
 
But... this means you need to modify PARAM.SFO (the signature changes)... so this only works when PARAM.PFD doesn't contains the signature of PARAM.SFO (only a few old games)
 
Also, This can be used together in combination with the previous methods (1ºencrypted + 2ºsigned + 3ºcopy protected)

*'''ICON0.PNG''' in the table represents all the multimedia files supported by the XMB for this format like images, audio, etc... See: [[Content_Information_Files#Saved_Data_Utility_.28minis.29|Content Information Files - Saved Data Utility (minis)]]
 
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.
 
PSP remaster & PSP save for apps&game can also be exported/imported following the same path.
 
===Game Saves PSP Remaster===
 
*PSP remaster games:
 
Monster Hunter 3rd HD ver. (BLJM-85001)
 
K-On!Houkago Live！！ HD ver. (BLJM-85002)
 
Sangoku Musou Multi Raid 2 HD Version (BLJM-85003)
 
----
*Encrypt/decrypt PSP savedata: http://wololo.net/2014/02/02/release-sed-port-for-pc/
 
*Speculation:
PSP saves featured on FW 3.60, PSP remaster saves on FW 3.70 (with also [[Remote_Play#Remote_Play_compatibility| Adhoc]])
 
Gamesave function PSP<--->PS3 (SAVEDATA_USE_PS3_SAVE on psp emulator command)
 
*Notes about native support
Cobra dongle writes/reads PSP game saves from path dev_hdd0/home/'''<userid>'''/minis_savedata/'''<SAVEDATA_DIRECTORY>'''.

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.

====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 File Name (identifier of the block is on Hexa format)
 
 
Serial number file type name (on UTC): _CP_DDHHMMSSSSSSSSSS
 
When trying to copy not valid save data:
*From corrupted Data ( Blue Cube as Icon):On Informations: Lock Copying prohibited, when trying to copy:"the data is corrupted."
*from modified data : During process of copy: "the data is corrupted."
*from malformed header : During process of copy:  error 80029303.
 
Some values on the header are more "sensitive" than others.
 
Size: 9KB (when save data using one block), PS3 XMB display as 8KB.

(Using Memory Card Adaptor don t corrupt save data in normal case, you need to insist or copy to other Virtual Memory Card to avoid the error)
 
See [[Playstation_Update_Package_(PUP)#Problem_solving_.2F_tips |Tips related to USB Stick/Mass storage device]]
 
====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, can take a little before all are displayed) 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 (during game: option on Memory Card Utility).
 
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 previously 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)
Note: CONFIG file ( 1040 bytes, generated by PSP or PS3? //when VMP is not empty //can be update for the Game Saves PS1 board of this page) used as original SYSTEM.CNF (kind of autorun), similar use than the [http://www.ps3devwiki.com/wiki/Talk:Eboot.PBP#CONFIG CONFIG file] on USDIR
. 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)

====Extracting and Injecting single PS1 Game Saves in PC/PS3====
*1.- Make a copy (with FTP or any file manager) of one of your internal virtual memory cards, in path: dev_hdd0/savedata/vmc/ (e.g: mycard.VM1)
*2.- Rename the file extension to .MCR (e.g: mycard.MCR)
*3.- Use MemcardRex or PSXGameEdit to extract or inject individual game saves (identifyed al slots)
*4.- Rename the file extension back to .VM1 (e.g: mycard.VM1)
*5.- Overwrite the original file in your internal HDD with the new file
 
*Notes:
**By overwriting the original file with the new one the XMB doesnt need to be updated and the new file is loaded normally (the console has no idea of what happened). If the save data is not visible on XMB, copy an other save data block to your memory card, them it ll appear.
**When adding new virtual memory cards with different names to the internal HDD, the XMB is unable to detect them because his database has not been "updated", this is solved by the option "restore database" from recovery menu, or by importing a new valid memory card from USB (it seems this last option updates the XMB database to be enable to identify all the contents of dev_hdd0/savedata/vmc/)
**you can also select them from the options of the PS1 emulator during game (PS button-assign slots).

====Editing PS1 Game Saves icons in PC====
PS1 icons has a size of 16x16 pixels, each pixel can use a color from a palette of 16
 
PSXGameEdit has a very good icon editor, it has the basic functions (as replace the selection of colors of the palette, basic pixel-by-pixel painting, flip, mirror, and rotation). There is a "Files" button with the options import and export in '''.ico''' format (in gimp the correct format to import is: .ico 4bpp, alpha 1 bit, 16 colors palette)
 
It supports animated icons. There are 4 "mini" images aligned at the top intented to display the animation, the first 3 ones at the left are the 3 frames of the animation (there is a maximun of 3 in the format, for static icons all displays the same frmae)... the fourth "mini image" at the right is a preview of the animation (it moves in a loop when the icon is animated)
 
For static icons (marked in the main windows as "ANIM= N")... there is a "force anim" option... but it seems it breaks the structure of the file, better dont use it !
 
*MemcardRex has a very basic icon editor, the most important feature is it can export to: BMP, GIF, JPEG, and PNG

===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.

A standard Ps2 Memory Card is composed by 1024 blocks, each block contains 16 pages of 528 bytes, for a total of 528*16*1024=8.650.752 bytes (0x840000)
 
Total ECC data is 16*16*1024=262.144 bytes
 
This gives an available space to store data of: Total-ECC = 8650752-262144 = 8388608 bytes = 8mb
 
*Backup Blocks
Two complete blocks are reserved to deal with the possibility of the memory card being removed by the user when data is being saved. Writing data to card requires erasing and reprogramming an entire block
 
Before writing a block, both '''bblock1''' and '''bblock2''' are erased. Then a copy of the new data that is going to be written is stored in '''bblock1''', and the number of the block that is going to be written is stored in '''bblock2'''. The block being programmed is then erased and writed. Finally, '''bblock2 is erased'''
 
Recovery caused by removal of the memory card is implemented whenever a memory card is inserted into the PS2 by checking '''bblock2''', if it's not erased, then programming is assumed to have not been completed. The contents of '''bblock1''' are then copied to the block given in '''bblock2'''. Then '''bblock2''' is erased
 
*Error Correction Code (ECC)
The data area of each page (512 bytes) is divided into 128 byte long chunks and for each chunk a simple [[http://en.wikipedia.org/wiki/Hamming_code 20-bit Hamming code]] is calculated and stored in three bytes
 
The first byte contains the column (or bit-wise) parity bits, with the even groups in the lower nibble and the odd groups in the upper nibble. The second and third bytes contain the even and odd groups respectively for the line (or byte-wise) parity bits
 
The 3 ECC bytes for each of the 4 chunks are stored in order in the page's spare area for a total of 12 bytes

====Virtual Memory Card PS2 (.VM2)====
File structure is the same than a "original PS2 memory card", there are not apparent differences
 
*Speculation
Last place to store a PS3 identifyer is inside the FAT filesystem ?... maybe there is none
 
====PS2 Single Save ? (.PSV)====
 
====Virtual Memory Card Encrypted (.VME)====
 
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").
 
Wrote by ps3hen in ps3hax forums weeks ago
PSN PS2 games do not save to VM cards in the same way to original PS2 games and PS1 games do
Each user who plays a PSN PS2 Game and makes a save, generates two VM cards (one for each slot) especially for that user account, for that game.
Each time the game is loaded the user selected VM cards(chosen from the VMC ulitity) are um-mounted and the user's save file for that game mounts the dedicated PS2 VM cards to the PS3 Virtual MC slots.
When the game is quit, the dedicated VM cards are un-mounted. But for some reason the user selected VM cards are not re-mounted, this is when I knew they mounted dedicated VM cards for each save.
The save file structure goes like this:
/PS3/EXPORT/PS2SD/XXXX11111/ICON0.PNG
                                            PARAM.SFO
                                            SCEVMC0.VME
                                            SCEVMC1.VME
Side note: "XXXX11111" will be different to the Title ID inside the Param.sfo. Inside the Param.sfo is the original title ID of the game when it was a PS2 Disc Game.
 
===Memory Card Tools PS2===
[[http://www.csclub.uwaterloo.ca:11068/mymc/ mymc]]
mymc is a public domain command line utility for working with PlayStation 2 memory card images (.ps2) as used by the PlayStation 2 emulator PCSX2.
It allows save files in the MAX Drive (.max), EMS (.psu), SharkPort (.sps), X-Port (.xps) and Code Breaker (.cbs) formats to be imported directly into these images.
It can also export save files in eiter the MAX Drive and EMS formats. See the README.txt file included in the distribution below for more details.
 
====Extracting and Injecting single PS2 Game Saves in PC====
The method is the same one used in PS1, see: [[Game_Saves#Extracting_and_Injecting_single_PS1_Game_Saves_in_PC | Extracting and Injecting single PS1 Game Saves in PC ]], but here the file format is: '''.VM2''' (a virtual PS2 memory card in PS3 format), and '''.PS2''' (a 1:1 raw copy of a PS2 memory card). Both are the same
 
The PC program to manage this '''.PS2''' memory cards is "mymc" and also can be generated by the emulator "PCSX2". See: http://wiki.pcsx2.net/index.php?title=Memcard
 
*External forums manuals:
http://psx-scene.com/forums/f177/tutorial-ps2-psu-saves-ps3-internal-memory-card-without-memory-card-adaptor-103436/
 
====Editing PS2 Game Saves icons in PC====
In PS2 save Games the icon is a file with the extension '''.icn''' (any name is valid), is "linked" to the save game by the file '''icon.sys'''. The PC program "PS2 SaveBuilder v0.8" can generate this 2 files (included a black default icon)... the icon can be replaced later.
 
The format supports 3D objects (e.g: save games of tomb raider with a figurine of lara croft)
 
The program "bmp2icon.exe by sjeep" can generate a '''.icn''' in the correct format for importing to "PS2 SaveBuilder v0.8", additionally it can add a 3d object where your image is applyed as a texture over the faces of a basic 3D object, the options are: 3D rectangle, 3D cube, of flat square
 
The source image to importing in "bmp2icon.exe by sjeep" must be a 24-bit 128x128 pixel .BMP
