PARAM.SFO
SFO (System File O???) are used in folders wich content needs to be displayed in the XMB. In the same folder than the SFO are the "content files" (ICON0.PNG PIC0.PNG etc...) and in few cases (like in savegames) there is a PARAM.PFD for security reasons.
The parameters SFO contains can be simplyfied as imputs and outputs of the content:
- Contains the information strings needed to display the content in the XMB and his restrictions (e.g. name and version of a game).
- When executing the content, the SFO is sending "boot modifyers" (or flags) to the content to activate "speciall modes" (e.g. audio and video modes of a game).
SFX (System File in XML format) are used to create SFO's. Additionally SFX files are used in Blue-Ray disc games inside PS3_EXTRA folder to display content in XMB. In fact the values contained in both formats are the same and the conversion is easy from one format to the other
SFO and SFX can be "chained" in a structure of subfolders with a maximun of 3 levels (SFX format is used in level3).
Level2 SFO's can contain specific values than cant be used in Level1 (e.g. CATEGORY when used in level2 has lot of different and specific values). In the same way when ATTRIBUTE is used in level2 his valid values are completly different than when used in level1.
Internal Structure
Header
typdef struct Header { uint32_t Signature; /* Always PSF */ uint32_t Version; /* Usually 1.1 */ uint32_t Name_Table_Start; /* Start position of the Name_Table */ uint32_t Data_Table_Start; /* Start position of the Data_Table */ uint32_t Entries_Number; /* Number of entries */ };
Definition_Table
This structure repeats one time for every Entries_Number defined in the header. All values are in Little Endian
typedef struct Definition_Table { uint16_t Name_Table_Offset; /* Offset of the Name of the entry, from start of Name_Table */ uint16_t Data_Type; /* Type of data of the entry in the Data_Table */ uint32_t Data_Used; /* Used Bytes by the entry in the Data_Table */ uint32_t Data_Size; /* Total bytes reserved for the entry in the Data_Table */ uint32_t Data_Table_Offset; /* Offset of the Data of the entry, from start of Data_Table */ };
Valid Data Types | Description | Notes |
---|---|---|
04 00 | Present but filled with zeroes | In ACCOUNT_ID when not registered in PSN |
04 02 | utf-8 | |
04 04 | integer |
Name_Table
The entries of this table (and the next table) can vary depending of the kind of content displayed in the XMB (in other words... are defined by CATEGORY and restricted by the system).
Each entry of the table needs 1 blank byte after the name to separate them
The table has padding at the end to fit the total size in bytes to a multiplier or 4, this padding is added after the last blank byte of the last entry. If the last entry (included his blank byte) matches with a multiplier of 4 this padding doesn't exist
Data_Table
This table has no padding between entries neither at the end, padding is not supported in any way, "Data_Size" is in the "Definition_Table" and the space is reserved for each entry
The number of "Data_Used" bytes for each entry is in the "Definition_Table", it matches the "Data_Size" when the entry is an integer (integer entries uses all the reserved bytes) but can vary with utf-8 entries (e.g. TITLE of the game), additionally utf-8 entries needs 1 blank byte after the last character of the text string, this byte can be considered part of the string to count the "Data_Used" bytes for the entry in the "Definition_Table"
Internall Structure Examples
SFO
This is an example of a hand made SFO structure, it contains only 1 entry (TITLE_ID), i choosed this one because is short enought to explain the structure in 4 lines, needs padding at the end of the Name_Table, and the Data_Used is smaller than the Data_Size
0x0000 00 50 53 46 01 01 00 00 24 00 00 00 30 00 00 00 | .PSF....$...0... | 0x0010 01 00 00 00 00 00 04 02 0A 00 00 00 0F 00 00 00 | ................ | 0x0020 00 00 00 00 54 49 54 4C 45 5F 49 44 00 00 00 00 | ....TITLE_ID.... | 0x0030 41 42 43 44 31 32 33 34 35 00 00 00 00 00 00 00 | ABCD12345....... |
All the blocks of the file are explained in the next list, it has separated sections for header and the three tables.

ATTRIBUTE
Data type: Int32 Block fixed size: 4 bytes Bytes used: 4
This parameter contains a maximun of 32 flags that can be turned on/off to activate/deactivate speciall boot modes for the content.
Values are stored in "Little Indian" format, by converting them to "Big Indian" and then to binary is easyer to see in a "human readable" format how are ordered from older to newer (note that the list separates them in 4 blocks, each of this blocks are "filled" from top to bottom). The older flags are related to PSP in the first block because PSP is older than PS3.
Flags can be used in groups, to remove or add a flag from the group is needed to make an addition or a substraction of the values.

- PSP Remote Play
The format "MPEG4 AVC/AAC" only works when the other format "MPEG4 SP/ATRAC" is activated
- PSP Export
Can be activate depend to CATEGORY (HG and others?) and works only if "feel free to fill" checked by "feel free to fill"
- XMB In-game
Is a feature that lets you pause the game (with the PS button) and play your own music from the files stored in your HDD The formats supported are the same than the native ones, it support playlists and all the normall functions of the music player. It was introduced in firmware 2.40
- Move Controller warning screen
This screen (and the other warning screens) are displayed before the game is launched, them explains the correct way to use the move controller, navigation controller, and eye cam respectively
Each of this screens are displayed around 3 seconds, the game waits for them to appear so is a good idea to remove them to improve the loading time, the removing of any of the 3 screens has no effect of the controller support and the controller will work without them
A example of a bad use of this screens is "3.56 FJW cfw" that patches all SFO's to activate 2 of this flags to force all his users to see 2 logos (i cant comment one of them, and the other the gargoile) causing a delay in the timing to boot a game or program >:P
- Navigation Controller, and Eye Cam warning screens
Only works when "Move Controller" warning screen is activated
- Calibration Notification
This flag makes appear a calibration screen, but only when the controller has not been calibrated previously (or when is missconfigured)
- Stereoscopic 3D Warning Screen
This is a warning screen similar than the ones related with move peripherals, but only appear when you are using a 3D compatible TV (is intended to give you some seconds to catch your 3D glasses)
- Installable Packages in path PS3_GAME\PKGDIR\PKG** (where ** is a number from 00 to 99)
This is one of the 2 ways to install packages (used in Blue-Ray discs), it can be said that the flags is "activating" the sub-folder PKGDIR, inside PKGDIR there is another SFO that can be considered an "Level2 SFO"
The ATTRIBUTE of this "Level2 SFO" is always an "1" (different of the values explained in this table that are only applicables to "Level1 SFO's"
- Enable game purchase
Only works if the category is a DG/HD and checked by "feel free to fill". Can change somes settings as titles, parental lock level, resolutions, and others Content Informations Files (probably related to expirations and such) after you purchased the game.
- Move compatible
Enables support for the Move Controller (Navigation Controller and Eye Cam are activated at the same time that the Move Controller and doesn't have/need a flag)

Is the most weird parameter of all the list, because is the only one that contains severall strings, one of this strings is another parameter (ACCOUNT_ID), and his size is huge for being an integer.
Based in the name... the way it works can be related with other parameters like: PARAMS2, HYBRID_PARAM, and COMMERCE_PARAM (all this parameters can be considered unknown by now)

Suggestions... (this will be erased later)
This section will be long, we need to reuse the old texts as most as possible but making the explains more "generall"
To separate PSL1GHT PARAM.SFO & PS3SYS PARAM.SFO part for an other page (under Talk page) to gain spaces. Also if you have an idea about what is HYBRID_PARAM or COMMERCE_PARAM thanks you.
