PARAM.SFO

SFO (System File Object) are used in folders which content needs to be displayed in the XMB.

The basic file/folder structure of a PS3 content is composed by a SFO, the multimedia Content Information Files, and for special content like Game Saves or Trophy files there is a PARAM.PFD for security reasons, other type of content like games or apps needs an structure of subfolders with names as INSDIR, LICDIR, PKGDIR, TRPDIR, USRDIR, etc...

The values contained in a SFO can be simplyfied as inputs/outputs for/from the content:

• Boot modifyers (flags) that are sent to the content when is executed to activate special modes (e.g. audio and video modes of a game).
• Information texts about the content and his restrictions (e.g. title and version of a game).

SFX (System File in XML format) is similar than SFO but without the data related to his structure (the SFO metadata that has no real value).

The conversion between the 2 formats is direct because the important values contained in both formats are the same (version, param_key, param_fmt, param_max_len & param_data).

SFO's and SFX's can be chained in a structure of subfolders where the "main" SFO activates a special subfolder, and the subfolder contains another SFO that activates another subfolder and so on.

This structures are limited by the system and activated by a combination of CATEGORY and special flags on ATTRIBUTE.

In Blu-Ray discs, the "main" PARAM.SFO itself is activated by another flag inside PS3_DISC.SFB.

Internal Structure

header

Code Sample

index_table

This structure is repeated the number of times defined in index_table_entries in the header. All values are in Little Endian.

Code Sample

key_table

The entries of this table (and the next table) can vary depending of the kind of content. Are always ordered alphabetically (from A to Z), each entry of this table is NULL terminated with 1 blank byte (0x00) to separate them. The valid values used in the most common content types are grouped in Parameters Table for a fast reference.

The table has padding at the end to align their size to a multiply 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 multiply of 4 this padding doesn't exist.

data_table

This table has no padding between entries neither at the end, param_max_len for each entry is stored in the index_table and this sizes are fixed by each entry (e.g. RESOLUTION always has a param_max_len of 4 bytes), so the space in data_table can be considered reserved (filled with zeroes when not used).

• Integer entries uses all the reserved bytes, so the param_len is the same as param_max_len.
• utf-8 entries never uses all the reserved bytes, needs 1 blank byte after the last character of the text string, this blank byte can be considered part of the string to count the param_len bytes for this entry (e.g. the title "my homebrew " has a param_len of 12 bytes from the total of 128 reserved in param_max_len).

param_fmt: Partially known based in some examples found in different content

param_fmt	Format	Notes
04 00	utf-8 Special Mode	Used in contents generated by the system, e.g: Game Saves (ACCOUNT_ID, PARAMS, PARAMS2, SAVEDATA_FILE_LIST, SAVEDATA_PARAMS)... and Trophies (PADDING)
04 02	utf-8	Character string, NULL finished (0x00)
04 04	integer	32 bits unsigned

Internal Structure Examples

Both example files (SFO & SFX) are hand made (the structure is correct but are only a minimal example). Both contains the same info but in different format: only 1 entry (TITLE_ID) and the value for this entry (BLUS12345)

The difference between them is SFO contains the "metadata" info related with his structure, and SFX dont (its XML code).

SFX

Code Sample

SFX are used in some disc with special content. See CATEGORY For Disc Contents
SFX Can be used as "templates" to generate SFO files
SFX Can be created using a SFO as the "source". See: SFO2SFX

SFO Requirements for Trophies

Trophy installations uses a PARAM.SFO without CATEGORY, can be considered different than the others because XMB doesnt identify them based in his CATEGORY but the format is the same

His placement in XMB up to firmware 4.25 was in "Game" column... after 4.30 are placed in "PlayStation Network" column, this placement in XMB is not dependant of his CATEGORY

Trophy folders are generated by a trophy installer (TROPHY.TRP), for more info see: Trophy files

• The requirements of this type of PARAM.SFO are displayed in the previous table with a "fake" CATEGORY marked as: "╦"

Parameters Descriptions

Filled with zeroes when the user has not been registered in PSN.

ACCOUNTID

param_fmt: utf-8
param_max_len: 0x10 (16 bytes)
param_len: 0x10 (16 bytes)

Used by: Trophy

Same string than ACCOUNT_ID but stored as utf-8 because the system uses it for normal functions (in this case is sent to PSN to synchronize the trophy data with your online account).

• PSP Remote Play v1 and v2

Remote play is a feature that displays the PS3 screen on a PSP to enable remote operation over a wireless LAN. There are two PSP Remote Play modes, "v1" is in low quality using MPEG4 SP/ATRAC codecs, and "v2" uses MPEG4 AVC/AAC. See: Remote Play page and Official video in youtube.

• PSP Export

Allows the copy of the content to a PSP by pressing triangle over his icon in XMB and the option "copy" in the side menu. Used by "PS1 Game", "Minis Game" and "PSP Game".

From FW 4.00, this option have been removed and the copy to a psp (or install on XMB) is from "bubbles" PKG (the flag is still used there). After been copied, you can still keep the pkg.

• XMB In-Game Forced Enable

XMB In-Game v2 was implemented in firmware 2.40, before 2.40 there was an old XMB In-Game v1. Games released before firmware 2.40 uses "XMB In-Game v1" even when launched in higher firmwares. This flag activates "XMB In-Game v2" for this old games, it has no effect in games released after 2.40 because this ones has XMB In-Game v2 activated by default. See: Official introduction video of the feature in fw 2.40.

If pressing home button for few seconds, XMB In-Game V1 will appear even in recent games. Some games such as Fritz chess got even 3 different XMB In Game: V2 when the game is launched, V1 during autosave feature screen, and a kind of V1.5 after (ICONS barely visible and no background visible)

• XMB In-Game Disabled

Replaces "XMB In-Game v2" by "XMB In-Game v1", works with all games, useful to free ram and to improve the loading time of the menu.

• XMB In-Game Background Music

Allows to pause the game (with the PS button), play your own music from the files stored in your HDD, and return to the game while your music is playing. This feature enables a SPU (inside CELL) that runs an specific thread to play the music independently of the other game threads (is a feature of the firmware, not of the game)

• System Chat voice

Disabled ? (or supported): not tested/found/used in apps

Speculation: was valid before Jun 2010 flags (maybe for some "Home" tests related with voice chat)

• PSvita Remote Play 480p (852x480)

Used for first time by "patch v3.52" for "torne" (IP9100-BCJB95006_00-TORNE0PATCH00352-A0352-V0352-PE). Previously torne had 2 flags for the two PSP remote play modes. This patch was released few days after PS3 firmware 4.00, in his chagelog there is a clear reference to PSvita connectivity with PS3 but its not verifyed (and cant be tested in a firmware before 4.00)

• Move/Navigation/Eye (warning screens)

This warning screens are displayed before the game is launched (around 3 seconds each), are an explain of the correct way to use the "move controller", "navigation controller", and "eye cam" respectively. The game waits for them to appear so is a good idea to remove them to improve the loading time, the removing of this 3 screens has no effect over the controller, move controller will work without them.

• Calibration (notification screen)

This is a calibration screen that appears when the controller has not been calibrated previously (or when is miss-configured).

• Stereoscopic 3D (warning screen)

This is a warning screen similar than the ones related with move peripherals, only appears when the TV is "3D compatible".

• Install Disc

Hides the primary icon of the disc (only the secondary icon is displayed), used when the disc contains only "Install Packages" and there is no bootable content on the "main" path (PS3_GAME/USRDIR/EBOOT.BIN).

• Install Packages

Activates the subfolder structure PS3_GAME/PKGDIR in discs by loading another SFO from this subfolder (the system loads the "main" SFO from PS3_GAME, and then "jumps" to the "secondary" SFO), every time one of these SFO's inside substructures/subfolders is loaded... a new subicon/mount point is loaded in XMB. See the examples in "fake disc structure"

• Game Purchase Enabled

Activates the option to purchase the content by pressing triangle over his icon in XMB. is directly related with CONTENT_ID. When the content is purchased his CONTENT_ID is checked online to obtain the license. After the license is retrieved the game loads another PARAM.SFO from a subfolder with different values (e.g. PARAM.SFO from the subfolder, as C00, with the TITLE "Full" is loaded, and the main PARAM.SFO with the TITLE "Demo" is ignored)

• Move Controller Supported

Enables support for the Move Controller (Navigation Controller and Eye Cam doesn't have/needs a flag)

• License Logo Disabled

Removes the "About this Game" option in Side Menu (by pressing triangle over the icon in XMB). This option ignores the LICENSE text. Used by games that has his own license and not the sony one (e.g: PCengine & NeoGeo)

• Unknown flag n21

When activated, "XMB in Game" for software is used (e.g.:"Do you want to quit the software now?" similar for apps category) and "About this Game" option is removed (on HDD category). It don t really means it s used for software such AP, AM etc...but can be also during other process such patches etc...

ATTRIBUTE in Patches

When a patch for a game (e.g: a disc game) is installed, the game boots from the "patch installation" folder, XMB loads from this folder his Content Information Files, a new PARAM.SFO, and a new EBOOT.BIN

After one of this installations PS3 loads both PARAM.SFO's (the "original.sfo" one from disc + the new from the "patch.sfo" folder)... some values are taken from the "original.sfo" (e.g: BOOTABLE, RESOLUTION, SOUND_FORMAT... are not present in patches)... and others are taken from the "patch.sfo" (e.g: APP_VER increases in every patch)

Patches uses a system of "overwrite flag/param_key" that makes the PS3 ignore the "original.sfo" value and use the value from the "patch.sfo"... this can be used in combination with the "standard flags" (one flag indicates the value must be taken from the patch... and the other flag activates the feature)

Blu-Ray disc structure details:

PS3 Blu Ray

These are "fake Blu-Ray discs" with the minimal values inside SFO's/SFX's needed for the structure to work, and the needed HYBRID_FLAG's inside the main PS3_DISC.SFB. All the files are 100% hand made from scratch and tested.

Game discs in folder PS3_GAME The basic structure of a game disc.

PS3 Blu Ray video content

PS3 Blu Ray install content

Themes folder is mounted as a "secondary icon" under the "main game icon". Doesn't need/admit an SFO/SFX, the icon contained in the theme is resized and displayed inside a bubble, also the TITLE of the Theme is used for the content.

Video folder is mounted on video column. Videos can not be copied to the internal or external storage.

Game discs in folder PS3_GAME/PKGDIR

PS3 Blu Ray

Can be considered an "expansion" of the basic blu-ray structure of a game disc, activated by the flag 00000200 in the ATTRIBUTE of the PARAM.SFO inside PS3_GAME. Packages are displayed in subfolders inside bubbles with his icons resized.

When the packages are installed, the file PARAM.SFO from PKGDIR is renamed to DISC.SFO and copyed inside the installation folder.

               |--- INSTALL.PKG

Game discs in folder PS3_GAME/INSDIR Can be considered an "expansion" of the basic blu-ray structure of a game disc, activated by default ?

Used for "game patches" and "game expansion packs". The PARAM.SFO inside "INSDIR" contains the "APP_VER" of the bigger patch of the folder. Note that "download content" packages doesnt contains "APP_VER" so his installation doesnt updates the main game. For this reason "APP_VER" is only related with patches and is only needed when there are patches in the folder.

Others type of PKG can be installed but the main game will reload the message below because it was expecting to have a game patche (?) for boot.

"This game cannot be started unless it is installed on the system storage. To install on the system storage you must create a game partition of %. Do you want to start installing? Yes No"

You can download this structures to experiment with them or to look how SFO's SFX's are built ---> [Blu-Ray fake discs by sandungas]

• Remove-insert again disc might be required to make structures appears.

• DISC.SFO seems to force the user to start the installed game with the original disc with this message on XMB:

"to play this game, you must insert the following disc. Insert the disc, and then start the game 
again.  (8001003E) Install disc"

This can/should be resolved by launching BD emulator, removing the disc.sfo file, or using the Lxx folders

It is a scale to rate the content for the different users based in user profile settings and international rating systems as: [| PEGI], [| ESRB], [| CERO], etc...

The higher the level the higher the restriction e.g:

• A game rated 11 will be displayed with an "locked" icon in XMB and requires the "unlock PIN" for a user with level 1.
• A game rated 1 can be played by all levels, from 1 to 11.
• Level 0 is disabled.

Game Selector Boot Process

When the disc boots, the EBOOT.BIN loads APP_CHOOSER.SELF, is a "game selector" and contains 5 games: half life 2, half life 2ep1, half life 2ep2, Portal, and Team fortress 2

Each of this games has his own .SELF and his own SAVECONTENTPS3 folder (each game uses different Content Information Files when generating his savedata). There is another savedata folder generated/loaded by the selector that is common. In some games (e.g: portal 1) there are several savedata folders to store: the "game settings", "autosave", and "manual save"

All the PARAM.SFO's generated in this savedata folders contains SAVEDATA_LIST_PARAM with a param_len of 7 bytes, and his values are strings of 6 numbers + a zero (NULL terminated)

The value stored by this game in SAVEDATA_LIST_PARAM is the "size of the folder on disk". This size is dependant of the filesystem (512 bytes cluster size in UFS2), and how many clusters are taken as the "minimun chunk" (that seems to be 2 clusters)

Because the writing process standards (and from the point of view of available clusters for the next writing operation) when a single byte is used in a cluster, this whole cluster is considered "not available for next writing process of a new file". This means e.g: that a file with a size 513 bytes uses 2 complete clusters (512 bytes in the first cluster and 1 byte in the second cluster, both clusters are reserved for this file)

To calculate the number of clusters used by a folder... is needed to calculate the number of clusters used by each file inside the folder, this includes the files that uses a number of clusters that is not even and needs to be "rounded-up". e.g: a file with size 1 byte (that is supposed to fit in 1 cluster) uses 2 clusters because the number "1" is not even. In few words, the number of clusters used by a file needs to be "rounded-up to next even number"

• This save game is a good example because always contains the same values in SAVEDATA_LIST_PARAM (the second one from euro region, that is only the game settings, lol):

	138.142	273 clusters	276 clusters	141312 (SAVEDATA_LIST_PARAM)

• The process is:
  • 1.- Divide by the cluster size
  • 2.- Round-up cluster number (if needed)
  • 3.- Multiply by the same cluster size (to know the amount of bytes reserved for this clusters)

This can be simplifyed by using 1024 (2 clusters)... because this way there is no need of step 2 (the "round-up")... but i have no idea if naming this "chunk" of 2 clusters a "page"... or why UFS2 filesystem takes them 2 by 2... i prefer to left this example as is, feel free to correct me

Also, there is a simple "trick" that can be used to display the files divided in clusters of the size you want (maybe are others but this is the faster way i found). By formatting a usb pendrive in advanced mode, using the cluster size your need, then moving the folder there (by using FAT32 with 1024 bytes cluster the value reported by your operative system is the same one stored inside SAVE_DATA_LIST)

• Other TITLE_ID's
  • TEST12345 (in savedata). When mounting a disc in a backup manager using the option "direct boot", the mounted disc use the TITLE_ID from backup manager (TITLE_ID from backup manager has not been unloaded properly and the disc adopts it). The savedata of this game will use TEST12345. When several different games are mounted and "direct launched", the savedata will be corrupted/invalid (because the overwriting of PARAM.SFO). TEST12345 seems to a common TITLE_ID used in all backup managers, the name probably is derived from official tools or internal firmware functions (Described as tips with ps3.gen.exe:"setting the TITLE_ID to TEST-XXXXX or disc version to "00.00" enable the program to build the disc image even when errors are found).

Disc revision, or Package revision. The number increases when the content is re-released or re-packaged for whatever reason that doesn't affect the main executable (e.g. when a disc game reaches platinum sales, or "game of the year edition" including extra contents).

When the main executable is updated, the APP_VER increases (this can be done with patches)... but the VERSION of the patch (or the re-released disc) returns to 01.00.

Additionally this gives the possibility to release different versions of the same patch (used when the original patch contains a bug, needs to be replaced, and is not cumulative)

The format is XX.YY where "XX" and "YY" are numbers, and the point "." is included in the string, e.g: 01.00.

• When used in a SFO for a trophy it has a param_len of 3 bytes, with the format: X.Y e.g: 1.0

Tips & Tricks

This section is to add more extended explains about features that cant been easily clasifyed inside other sections

Replacing a PARAM.SFO manually

When replacing a PARAM.SFO manually in the internall HDD (using a file manager, FTP, etc...) the system ignores it. This happens because the system is storing a "duplicated" copy of the old one.

To be sure that the new PARAM.SFO has been loaded you can change the TITLE (Paid attention also to TITLE_xx) , this way you can see the new name displayed in XMB, is a good idea to use something that identifyes the change as "My test 01".

• The most convenient and quick way to "refresh" the XMB is as simple as booting the game one time (by pressing X button over his icon)... inside the game press "PS" button and exit with "quit"... then return to the XMB and the new PARAM.SFO has been loaded. So in resume... the XMB is refreshed when you boot it for first time so you need to boot it one time and quit to load the new PARAM.SFO.

• The other solution is by using the option "rebuild database" from the recovery menu (this re-indexes all the files in the internall HDD), is long but can fix rare problems. This can be used when the PARAM.SFO you are playing with is not BOOTABLE (you cant boot it to "refresh" the XMB)

When replacing a PARAM.SFO manually in a Game Disc (to be loaded later by a backup manager) sometimes the system ignores it. This happens because the system is storing a "duplicated" copy of the old disc structure included his PARAM.SFO (iirc). The trick to "refresh the XMB" is again by booting the game (pressing X in the main icon)... for this to work is needed to have a EBOOT.BIN in the main path inside USRDIR folder (e.g: the EBOOT.BIN from the "move demo disc" just plays a video in .MP4 and is tiny)

Creating a frankenstein PARAM.SFO

PS3 Blu Ray "corrupted data"

The first step is to go to the Parameters Table to look wich param_key's are mandatory and wich ones can be removed or zeroed (note this table has a lot of YES that probably are OPT, is just that this ones has not been verifyed or found)

• When you generate a non proper file you can have a nice icon of "corrupted data", but in some cases the game boots normally. In other cases when adding or removing param_key's the file is "partially" corrupted because there is a "break point" in the structure and the file is "partially" loaded (the PS3 loads the values before the structure "break point" normally, but after this point the values shown as corrupted or missing). Try to boot from app_home if needed.

• When adding "non-standard" param_key's to a SFO for an specific type of content (that only admits a few ones) the SFO is loaded without problems but firmware ignores them because are "not-expected" (e.g. when adding SUB_TITLE to a SFO for category "HG").

• The minimal structure tested (and working) for a homebrew can be copied/downloaded at the bottom of the page, its not "standard" but the PS3 doesn't complain, and probably can be reduced even more.

• If Error 80028F08:

can be resolved by pressing triangle one time and launch the game from start or back from the ICON.

Creating Discs

The "fake blu-ray" structures that can be downloaded from this page uses two "dirty tricks" that was usefull to identify the critic values needed to work, but can be a bit confusing to replicate them.

The first one is the removing of TITLE and TITLE_ID from most of the SFO's, this can generate a strange behaviour mostly for the primary icon. The second one is the ATTRIBUTE flag to hide the main icon. The other factor involved in this weird behaviours are the "backup managers" that are hardcoded to look for files and format in some specific structures.

When playing with this fake blu-rays use a USB pendrive (is faster to connect/disconnect to ps3/pc) with a "GAMEZ" folder in the root, and remember to "dismount" the game before disconecting the USB to avoid the XMB to go crazy, also remember the XMB sometimes keeps a backup copy of the old PARAM.SFO

For install packages (max: 100, FW min: 1.80) you can use PS3_EXTRA or PKGDIR both will work but are displayed different

For themes ( max: 200, FW min: 2.50) and videos (max: 200, FW min: 2.40) use PS3_EXTRA or PS3_CONTENT remember themes includes his own icon and title, videos are mounted in video colum when using PS3_CONTENT pretty nice for chapters of series, video manuals, etc...

(Max items & FW min are theory, not tested)

For patches use INSDIR, his installation is more automated

Creating Patches

The type of patch is defined by his APP_VER, TARGET_APP_VER, and VERSION. There is no way to update an installed content without APP_VER The standard way to install a patch is by using the same TITLE_ID of the previous release and a bigger APP_VER, when the patch is installed his PARAM.SFO replaces the old one, consequently his APP_VER increases

But there are some tricks related with this patching system that can be used to add files to the install folder without keeping this standard:

• Using a "blank" APP_VER

This is as easy as filling the value for APP_VER in the patch with zeroes, the undesired effect is the app will have no version. The benefit is this will work for installing cummulating files as "themes", "roms" etc...

• Using the same APP_VER and TARGET_APP_VER in the patch and in the app

This will replace the PARAM.SFO by other with the same values, so is similar than the previous one, but keeping his version. Additionally this assures you that the files are compatibles with this version of the app (e.g: a theme that only works with a specific version)
