Memory Card Formats PS1
Memory card PS1 (original)
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.
Original Memory Card PS1 (128 KB) (on PS3 XMB display : freespace available / 120KB) |- Header Block 0 (this block is not accessible and visible from menu) | |---1 Header Frame ( 128 bytes) | |---15 Directory Frame (1920 bytes) | |---20 Unused Frame (2560 bytes) | |---Filled with FF (3456 bytes) | |---others ( 128 bytes) | (total: 8192 bytes : 8 KB) | |- Data Block 1 (adress: 0x2000 , blocks are visible on screen, one game can use more than one block) | | | |---Frame 0 (File Name: 128 bytes, see Frame 64 on .VM1) | |---Frame 1 (Icon: can be different at each BLOCK for the same game) | |---Frame 2 (Icon: can be combined for animation or for PocketStation Icon) | |---Frame 3 (Icon: same as frame 2, max animation use 3 frames) | |---Frame 4 (Save Data) | |--- ... | |---Frame 63(Save Data) | (total 64 frames: 8 KB) | |- Data Block 2 | |- Data Block 3 | |- ... Data Block 15
- Total memory card size 128KB = 131072 bytes = 0x20000 bytes
- 1 Block = 8KB = 8192 bytes = 0x2000 bytes
- 1 Frame = 128 bytes = 0x80 bytes
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 0x8A inside virtual_memcard. VM1,0x64 for .PSV)
Serial number file type name (in UTC): _NEW_DDHHMMSSSSSSSSSS

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 identifier of the block on Hexa format
The file format has a 0x84 bytes header, in a PS1 Memory Card every slot is 0x2000 so if the savedata is composed by only one slot the total file size is 0x2084 (8.324 bytes). In PS3 XMB is displayed as 8KB
A part of the header is common for PS2 (most, but for PS2 is bigger)

Virtual Memory Card PSP (.VMP)
VMP is a PS1 memory card in "PSP format". Total memory card size is 129 KB = 131200 bytes = 0x20080 bytes (0x80 bigger than a real PS1 memory card)
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 CONFIG file on USDIR . All in PSP format, never updated, and not intended to store Save Games, only to export them

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
- 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
