Editing PARAM.SFO

==Description==
'''SFO''' ('''S'''ystem '''F'''ile '''O'''bject) 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 (most of the int32 datas) that are sent to the content when is executed to activate specific features or settings (e.g. audio and video modes of a game).
**Information texts (most of the utf8 datas) about the content and its restrictions (e.g. title and version of a game).

'''SFX''' ('''S'''ystem '''F'''ile in '''X'''ML format) is similar than SFO but without the data related to its 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.

These structures are limited by the system and activated by a combination of [[#CATEGORY|CATEGORY]] and special flags on [[#ATTRIBUTE|ATTRIBUTE]].

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

==Internal Structure==
===header===
At offset 0x0, length 0x14 (20 bytes)
{{Boxcode|code=<syntaxhighlight lang="c">
struct sfo_header
{
uint32_t magic; /************ Always PSF */
uint32_t version; /********** Usually 1.1 */
uint32_t key_table_start; /** Start offset of key_table */
uint32_t data_table_start; /* Start offset of data_table */
uint32_t tables_entries; /*** Number of entries in all tables */
};
</syntaxhighlight>}}

===index_table===
At offset 0x14, composed by a number of entries defined with '''tables_entries''' in the '''header''', each entry is 0x10 length (16 bytes). Values are in Little Endian.

Every entry belongs to a '''key''' name in the '''key_table''' and defines a '''data''' area in the '''data_table'''

{{Boxcode|code=<syntaxhighlight lang="c">
struct sfo_index_table_entry
{
uint16_t key_offset; /*** param_key offset (relative to start offset of key_table) */
uint16_t data_fmt; /***** param_data data type */
uint32_t data_len; /***** param_data used bytes */
uint32_t data_max_len; /* param_data total bytes */
uint32_t data_offset; /** param_data offset (relative to start offset of data_table) */
};
</syntaxhighlight>}}

|-
|}

===key_table===
Composed by a number of '''key''' entries defined with '''tables_entries''' in the '''header''', are short utf8 strings in capitals, NULL terminated (0x00), and ordered alphabetically (from A to Z). This alphabetically order defines the order of the associated entries in the other two tables ('''index_table''', and '''data_table''')

The end offset of this table needs to be aligned to a multiply of 32bits (4 bytes), this is made with a padding at the end of  '''key_table''' when needed (in a few SFO's the table is aligned naturally as a coincidence caused by the length of the '''key''' names used, when this happens there is no padding needed)

===data_table===
Composed by a number of '''data''' entries defined with '''tables_entries''' in the '''header''', every entry in this table is defined by the associated entry in the '''index_table''' by using: '''fmt''', '''len''', '''max_len''', and '''offset'''. There is no padding between entries neither at the end of this table

Some '''data''' entries can be filled with zeroes (not used, but availables for being used). This entries can be considered reserved, and are marked with a '''len''' = 0 in the associated entry in the '''index_table'''

==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 bigger difference between SFO and SFX is SFX doesnt contains:
**SFO header
**Key and Data offsets
**Data used length

Trophy folders/files are created by a trophy installer (TROPHY.TRP). See: [[Trophy files]]

==Parameters Descriptions==

===ACCOUNT_ID===
{{Boxinfo3|content='''param_fmt''': utf8-S<br />'''param_max_len''': 0x10 (16 bytes)<br />'''param_len''': 0x10 (16 bytes)}}
{{Boxtip1|content='''Used by''': Save Data}}

PSN User Account stored as '''utf8-S'''. The string is compared with the user info in [[XRegistry.sys]]. The comparison can only return two values, right, or wrong, if the comparison returns right the SaveData is valid.

When the user/console has not been registered in PSN = 0000000000000000

When the savedata ownership has been removed (by official DEX feature "fake save data owner") = FFFFFFFFFFFFFFFF

====ACCOUNTID (for trophies)====<!--messed up name when trophies was implemented-->
{{Boxinfo3|content='''param_fmt''': utf8<br />'''param_max_len''': 0x10 (16 bytes)<br />'''param_len''': 0x10 (16 bytes)}}
{{Boxtip1|content='''Used by''': Trophy}}

Same string than ACCOUNT_ID but stored as '''utf8''' because the system uses it for normal functions (in this case is sent to PSN to synchronize the trophy data with your online account).

===ANALOG_MODE===
{{Boxinfo3|content='''param_fmt''': int32<br />'''param_max_len''': 0x4 (4 bytes)<br />'''param_len''': 0x4 (4 bytes)}}
{{Boxtip1|content='''Used by''': PS1 Game}}

*'''Analog Mode Enabled'''
Enables compatibility with the analog sticks of the Dualshock Controller.

Digital is single stick mode i.e. remapping the dpad, Analog is twin stick mode or flightstick mode
* http://en.wikipedia.org/wiki/PlayStation_Controller (digital only)
* http://en.wikipedia.org/wiki/Dual_Analog_Controller (Dual analog, can be set digital with analog button)
* http://en.wikipedia.org/wiki/DualShock (Dual analog with rumble, can be set digital with analog button)
* http://en.wikipedia.org/wiki/PlayStation_Analog_Joystick (Dual analog, can be set digital with analog button)
Note: DualShock3+SixAxis are the first to remove the analog button, but can be set in digital mode by software (hence the need of this setting)

*Questions:
**It works (and can be enabled) in PS2 classics ?
**In case of working in PS2 classics... is needed ? (is posible Dualshock 2 enables it by default, so can be pointless)
**On Cobra cfw (not classic) analog mode is auto selected when a PS2 game needs the function, digital mode is grayed out and cannot be highlighted.
**Is posible to disable it ? (in PS1 classics the default mode seems to be disabled so can be pointless, but for PS2 Classic and in case of enabled by default it could be posible to disable)
<!--// please, replace this questions with a short answer that clarifyes it //-->

===APP_VER===
{{Boxinfo3|content='''param_fmt''': utf8<br />'''param_max_len''': 0x8 (8 bytes)<br />'''param_len''': 0x6 (6 bytes)}}
{{Boxtip1|content='''Used by''': HDD Game, Minis Game, PSP Remasters Game, Game Data}}


Application version (or patch version). Not used in old games.

The format is '''XX.YY''' where "'''XX'''" and "'''YY'''" are numbers, and the point "'''.'''" is included in the string, e.g: '''01.00''' for the first stable version released.

*Cummulative Patches
Game patches uses a bigger '''APP_VER''' as '''01.01''' for the first patch, but keeping the same [[#TITLE_ID|TITLE_ID]] from the original release.

Contains a maximun of 32 flags that can be turned on/off to activate/deactivate special boot modes and features of the content.

Values are stored in "Little Endian" format inside the SFO, to represent the whole tables in a "human readable" format has been needed to convert them to "Big Endian" and then to "[http://tizzyt-archive.blogspot.jp/2013/08/learning-binary.html Binary]".

Remote play is a feature that displays the PS3 screen on a PSP or a PSVita enabling remote operations over a wireless LAN. See: [[Remote Play]]
}}

{{Boxframe0|content={{dot}}'''PSP Export''' ''(firmware v1.70)''<BR />
Used in PS1 Classics, PSP Minis, and PSP Games. Allows the copy of the game to a PSP by pressing {{padtriangle}} over the game icon and selecting the option <span style="background:#bbbbff;">[Copy]</span> in the side menu. This export process is closelly related with how the PS3 manages the downloads and installation of content from PSN using temporal subfolders in ''dev_hdd0/vsh/task/''. See [[Project Database (PDB)]]
}}
}}

{{Boxframe1|content='''XMB In-Game''' (short {{padps}} press)
{{Boxframe0|content={{dot}}'''XMB In-Game Forced Enable''' ''(firmware v2.40)''<BR />
Games released/compiled before firmware 2.40 doesnt uses "XMB In-Game" even when launched in higher firmwares. This flag enables "XMB In-Game" for these old games, the flag has no effect in games released after 2.40 because newer games has "XMB In-Game" enabled by default. See: [[XMB#XMB Modes|XMB Modes]].
}}

{{Boxframe0|content={{dot}}'''XMB In-Game Disabled''' ''(firmware v2.40)''<BR />
Disables "XMB In-Game", the flag works in all games and doesnt causes any problem, useful to free ram and to improve the loading time of the menu. See: [[XMB#XMB Modes|XMB Modes]].
}}

{{Boxframe0|content={{dot}}'''XMB In-Game Background Music''' ''(firmware v2.40)''<BR />
When enabled allows to play your own music from the files stored in your HDD by using the icon that appears in XMB {{icon category music}} column, is posible to play single songs or a playlist and then return to the game while your music is playing. See [[XMB In-game background music]]
}}
}}

{{Boxframe0|content={{dot}}'''System Voice Chat ?'''<BR />
Speculation: Not clear if the flag enables or disables voice chat, and not clear wich kind of voice chat (in the very probable case there are severals chat modes/types), supposed to be valid before Jun 2010, matching chronologigally the release of "home" (probably used in beta stages of the developing of chat functions inside "Home" enviroment to make internall tests related with voice chat). Enabling the flag manually for testing in different SFO's with different CATEGORY's didnt give any result

This warning screens are composed by several animated images loaded from ''dev_flash/vsh/resource/game_ext_plugin.rco''<!--// and ycon_manual_plugin.rco ? //-->, are displayed before the game is launched (around 3 seconds each), are an explain of the correct way to use "move controller", "navigation controller", and "eye cam" respectively. The game waits for them to appear so removing them improves the loading time, the presence of this 3 flags/screens has no effect over move controller support.
}}

{{Boxframe0|content={{dot}}'''Move Calibration Notification''' ''(firmware v3.40)''<BR />
This is a calibration screen composed by several animated images loaded from ''dev_flash/vsh/resource/sysconf/calibration/'', appears when the controller has not been calibrated previously (or when is miss-configured).

{{Boxframe1|content='''Discs'''
{{Boxframe0|content={{dot}}'''Install Disc'''<BR />
Disables the main/primary icon of the disc {{media ps3 bd}} (only the extra/secondary icons are displayed), used when the disc only contains "Install Packages" and there is no bootable content on the disc main path in ''dev_bdvd/PS3_GAME/USRDIR/EBOOT.BIN''.
}}

{{Boxframe0|content={{dot}}'''Install Packages'''<BR />
Loads a secondary SFO from path: ''dev_bdvd/PS3_GAME/PKGDIR/PARAM.SFO'' (the flag in the main SFO in path ''dev_bdvd/PS3_GAME/PARAM.SFO'' {{media ps3 bd}} enables the secondary SFO in path ''dev_bdvd/PS3_GAME/PKGDIR/PARAM.SFO'' displayed as a bubble inside a disc {{media ps3 bd install}}), the secondary SFO and the contents of this subfolder are mounted by XMB under the main disc icon in {{icon category game}} column. See [[#CATEGORY|BluRay Disc Structure]]
}}
}}

{{Boxframe0|content={{dot}}'''Game Purchase Enabled'''<BR />
Enables the <span style="background:#bbbbff;">[purchase]</span> option that appears in side menu when pressing {{padtriangle}} over the icon in XMB. Is directly related with [[#CONTENT_ID|CONTENT_ID]]. When the content is purchased its 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. main PARAM.SFO enables the purchase flag and could use the TITLE "Demo", when purchased other PARAM.SFO from a "C00" subfolder is loaded that could use the TITLE "Full".
}}

{{Boxframe0|content={{dot}}'''flag 1048576 (decimal)''' ''(firmware <4.00?)''<BR />
When activated, "XMB in Game" for software is used (when quitting an app that uses this flag the message displayed in XMB In-Game changes to: ''"Do you want to quit the software now?"''), and disables <span style="background:#bbbbff;">[About this Game]</span> option that appears in side menu when pressing {{padtriangle}} over the icon in XMB. This flag is used in combination with the parameter [[#BOOTABLE|BOOTABLE]] = 2 to make the software boot in a special mode
}}

{{Boxframe0|content={{dot}}'''PCEngine''' ''(firmware <3.41?)''<BR />
}}

{{Boxframe0|content={{dot}}'''License Logo Disabled''' ''(firmware <3.41?)''<BR />
Disables the <span style="background:#bbbbff;">[About this Game]</span> option that appears in side menu when pressing {{padtriangle}} over the icon in XMB. This flag also removes the needed of storing a [[#LICENSE|LICENSE]] param_key in the PARAM.SFO, the consequence of removing LICENSE param_key is the size of the PARAM.SFO file is reduced drastically (LICENSE text is huge in comparison with the rest of the file... SFO's without LICENSE are much smaller). Used by games that have their own license and not the sony one (e.g: PCengine & NeoGeo)
}}

{{Boxframe0|content={{dot}}'''Move Controller Enabled''' ''(firmware v3.40)''<BR />
Enables Move Controller support for the game. See [[Move Motion Controller]]
Note [[Move Navigation Controller]] is supported in all games because is a reduced version of [[DualShock 3]] and [[PlayStation Eye]] camera is enabled automatically when needed. This ones doesn't have/needs a flag

Disables the <span style="background:#bbbbff;">[Copy]</span> option that appears in side menu when pressing {{padtriangle}} over the gamesave icon in XMB. In other words... disables the gamesave export feature. Used only in PS3 Game Saves (CATEGORY: '''SD'''). See [[Game Saves]].
Note in PS3 Game Saves the PARAM.SFO is always included in the list of protected files that is stored inside PARAM.PFD, so after removing the copy protection flag in the .SFO is needed to generate a valid .PFD. See [[PARAM.PFD]]

'''Not Bootable'''
*Looks pointless because the SFO's for contents that are not bootable simply doesnt includes the parameter BOOTABLE (like savegames or trophies where BOOTABLE doesnt exists and if you include it manually the system ignores it), but in some specific cases the PARAM.SFO contains the parameter BOOTABLE with a value of 0 (e.g: in SFO's of CATEGORY '''PP'''... for PSP transferable games, where the game is not intended to boot on PS3, is only stored temporally in PS3 ready to be transfered to a PSP)

'''Bootable (mode 1)'''
*Used in all games that "boots" on PS3 (and all apps that boots on PS3, with the exception of the ones using bootable = 2 explained below)

'''Bootable (mode 2)'''
*After 4.00 firmware XMB can identify some bootable contents as "software" by using this flag ("bootable games" and "bootable software" should be considered different based on this flag, or they boots in different modes), is used in combination with the ATTRIBUTE flag 1048576 (in decimal), this flag displays an specific message from game_ext_plugin.rco/english.xml when quitting the software ''<Text name="msg_need_quit_to_operate_ask">To perform this operation, you must quit [%1]. Do you want to quit the software now?</Text>'', and ''"About this Game"'' is removed from the option side menu (infobar)
*Note the XMB mesages enabled with the ATTRIBUTE flag are specific for software (not for games), and the data type of BOOTABLE is int32 (flags), when looking at BOOTABLE flags in binary the flags are different (BOOTABLE flag 2 doesnt contains flag 1)
*The use of this flag is not completly known/documented, feel free to experiment and return back to edit wiki with new info <!--// instead of leeching for fame and glory in your kiddy circle :/ //-->

[[Content ID]]

Content Identificator for Gamepurchase feature. Used in games that runs in "demo mode" and can be purchased (unlocked) by pressing triangle over its icon in XMB.

The format is: '''XXYYYY-NP_COMMUNICATION_ID-LICENSE_ID''' where:
*'''XX''' is ?
*'''YYYY''' is ?
*'''-''' is a separator character (mandatory)
*'''NP_COMMUNICATION_ID''' is explained in [[#NP_COMMUNICATION_ID|NP_COMMUNICATION_ID]]

{{Boxtip1|content='''Used by''': Save Data}}

Text lines displayed under [[#SUBTITLE|SUBTITLE]] text. Used only for SaveData to store long texts from the game like the name of the level you was playing, the equipment of your character (in a RPG), or the car you was driving (in a race simulator), etc...

When the text is too long to fit in the screen it scrolls vertically from bottom to top, if the '''Data_Used_Size''' is not correct this scroll doesn't flow properly.

The special byte "'''0A'''" displaces the text to the next line (a linefeed), this can be used to create long texts composed by several horizontall lines.

*Notes:
**The SFO parameter ACCOUNT_ID is the same than the ACCOUNT_ID inside PARAMS. When the parameters PARAMS & ACCOUNT_ID are present in the SFO the string can be found twice in the file (always happens in savegames). When the user has not been registered an account in PSN its ACCOUNT_ID is filled with zeroes
**When the SFO is generated the user/console data is taken from [[XRegistry.sys]]
**The system displays the time when the savedata was updated by reading the timestamp of PARAM.SFO


*Speculation:
**In the case one of the first bytes at the begining is used to store flags (second byte mostly because is the one that changes most in the samples found) there is a limited number of firmware features related with savegames that needs to work in a different mode based on a flag (this flags should be using as settings of the gamesave), some posible features enabled/disabled by this flags could be:
***Times the savedata was exported/imported to a external device (counters)
***Trophy disabled (not posible to unlock trophies from this gamesave, because was imported from external device and/or belongs to other user/console)
***Fake savedata owner (feature available in debugs)
***load trophy data when game boots (some games displays the list of trophies inside a game screen)
***savedata system screen replaced/hidden (some games uses their own savedata screen instead of the system screens, in this case the system needs to disable the default screens or make it invisible, like in tomb raider)
**Another option is the first bytes at the beginning are configuring the internal structure of the PARAMS area, by defining the counters types or their positions
**Another option is the first bytes are simply the version of the savegame (1.1, 1.2, 1.3, and so on...) this "gamesave versions" could be defining some requirements of the whole PARAM.SFO structure, or/and the security used by the related [[PARAM.PFD]] and other secured files in the gamesave

*Tests
**PS2 games remastered in PS3 format (not "ps2 classics") like "resident evil 4 HD" (CATEGORY=HG and TITLE_ID=NPEB00342) doesn't supports 1080 mode by default (or at least this one). 1080 mode in combination with SOUND_FORMAT (all SOUND_FORMAT modes enabled) the RESOLUTION flags are read but the PS3 crashes
**Note the resolution for original PS1 disc games can vary (See: [[Emulation#Resolution|Emulation Resolution]]). The RESOLUTION flags used in PARAM.SFO's of "PS1 Classics Game" from PSN seems to be specific and not fixed sizes (e.g: 01 00 00 00). This will need another table if more are found

*There are special RESOLUTION values for PS1 and PS2 Classics, and PSP Remasters ?. The resolution for original PS1 disc games can vary (See: [[Emulation#Resolution|Emulation Resolution]]). The RESOLUTION flags used in PARAM.SFO's of "PS1 Classics Game" from PSN seems to be specific (e.g: 01 00 00 00 for NTSC games and 02 00 00 00 for PAL games). This will need another table if more are found

Name of the folder where the game stores its SaveData. The format is: '''TITLE_IDxxxxx''' (9 bytes + 22 bytes max), e.g;: '''BLUS00001_savedata_01''' where:
*'''TITLE_ID''' Identifier of the content. Explained in [[#TITLE_ID|TITLE_ID]].

In most of the savegames (when the game doesnt uses it) is filled with zeroes with a '''param_len''' of 1 byte (the null termination)

This area is available for the game to store "any" data, the purposes of this data is to avoid tampering with the files generated by the game, the usage of this area is optional for the game developers and can be considered a more deep security layer under the [[PARAM.PFD]] layer

Because the data is generated and recovered by the game, its type or usage can be different for each game, the next table contains some valid examples found:

*Tests
**PS2 games remastered in PS3 format (not "ps2 classics") like "resident evil 4 HD" (CATEGORY=HG and TITLE_ID=NPEB00342) only supports '''LPCM 2.0''' by default. In the first tests was impossible to activate other sound modes (the flags are ignored). In combination with RESOLUTION (all RESOLUTION modes enabled) the SOUND_FORMAT flags are readed but the PS3 crashes

*Other SOUND_FORMAT values availables in non retail (Debug, AV/Test, etc...) consoles ?

{{Boxtip1|content='''Used by''': Save Data}}

The line of text displayed under [[#TITLE|TITLE]] text, used only in SaveData to store short texts from the game like your player name, your play time, photo used or your rank in the game 

When the text is too long to fit in the screen it scrolls horizontally from right to left, if the '''Data_Used_Size''' is not correct this scroll doesn't flow properly. The same behaviour happens with TITLE, TITLE_xx, TITLEID0xx and TITLE_ID

{{Boxtip1|content='''Used by''': Minis Save Data}}

Subtitle of the Save, the format is the same than [[PARAM.SFO#SUBTITLE|SUBTITLE]]

<!-- ====SUB_TITLE_xx (for localized languages)====
Especulative, i dont remember to test it, but by looking at the sfo attributes used on vita it looks this one probably exists and is missing in ps3 wiki, is for localized subtitles texts in savedata contents, my bet is this feature is supported since firmware 1.00-->

{{Boxtip1|content='''Used by''': Game Data}}

Target application version for incremental patches. Patches containing '''TARGET_APP_VER''' can be installed over the game with the same '''APP_VER'''.

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

===TITLE===

{{Boxtip1|content='''Used by''': All but Trophy}}

Default "title of the game" for all languages. The text is displayed right to the ICON0.PNG.

The special byte "'''0A'''" displaces the text to the next line (a linefeed), this can be used to create long texts composed by several horizontall lines, the maximun number of horizontal text lines allowed for the TITLE is 3 (in other words... you can use the "linefeed" byte 2 times)

====TITLE_xx (for localized languages)====
{{Boxinfo3|content='''param_fmt''': utf8<br />'''param_max_len''': 0x80 (128 bytes)<br />'''param_len''': variable}}
{{Boxtip1|content='''Used by''': HDD Game}}

Same than TITLE but for localized languages.

An .SFO can contain several TITLE_'''xx''' where '''xx''' is a number for a regional code.

The "default" TITLE is always present when other "localized" TITLE_'''xx''' are used.

{{Boxtip1|content='''Used by''': HDD Game, PS1 Game, Minis Game, PSP Remasters Game, Game Data}}

Identifier of the content, in the format '''ABCD12345'''. Must be the same ID inside the Makefile when compiling the .SELF, or/and when creating the .PKG (also known as [[Productcode]])

{{TITLE_ID for Physical Media}}

{{TITLE_ID for Digital Media}}

*Other TITLE_ID's. See {{talk}} page
**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).
**TEST***** All the disc images generated for debug PS3's in the development stages of the game

====TITLEID0xx (for trophies with localized languages)====<!--messed up name when trophies was implemented-->

SFO's for trophies contains a full list of 16 TITLEID0'''xx''' for all languages where '''xx''' is a number for a language code.

All them can contain data, or only the default TITLEID000. The ones without data are marked with a ''' Data_Used_Size''' = 0 bytes

The text contained inside default TITLEID000 is the same than [[#TITLE_ID|TITLE_ID]]

===VERSION===

{{Boxtip1|content='''Used by''': HDD Game, PS1 Game, Minis Game, PSP Remasters Game, Game Data, Trophy}}

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'''

<div style="float:right">[[Image:icon media ps3 bd.png|200px|thumb|left|PS3 Blu Ray]]<br /></div>

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.

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'''
<div style="float:right">[[Image:icon media_ps3_bd_install.png|200px|thumb|left|PS3 Blu Ray install content]]<br /></div>

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

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

'''Game discs in folder PS3_GAME/INSDIR'''
Can be considered an expansion of the basic blu-ray disc game structure, activated by default with the "g" HYBRID_FLAG from PS3_DISC.SFB

The presence of INSDIR forces a mandatory installation (warning screen with "Yes" or "No", if selecting "No" the game doesnt boots) performed in main XMB (before starting the game). When the installation is completed the game boots

 Inside game_ext_plugin.rco/english.xml
 <Text name="msg_game_cannot_start_wo_install_need_area_install_ask">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 %1.
 Do you want to start installing?</Text>

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 its installation doesnt updates the main game. For this reason "'''APP_VER'''" is only related with patches. Other types of PKG can be installed but the main game will reload the message above because it was expecting to have a game patch.

'''dev_bdvd/PS3_GM01/''' is a folder at the same level than PS3_GAME, is used for multiboot game discs (the only disc structure that supports '''direct''' multiboot). Each eboot is mounted using its own {{media ps3 bd}} icon. This discs uses speciall LIC.DAT files, see: [[LIC.DAT]] page

The two numbers at the end of the name '''PS3_GM01''' looks like a counter, but only '''PS3_GM01''' is supported (other numbers are not supported... yet)

----

You can download this structures to experiment with them or to look how SFO's SFX's are built ---> [[http://www.sendspace.com/file/o95vde| 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 Lxx folders. See {{talk}} page

==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 its 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 its 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===
<div style="float:right">[[Image:Icon_media_disc_broken.png|200px|thumb|left|PS3 Blu Ray "corrupted data"]]<br /></div>

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 its 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, its installation is more automated

===Creating Patches===
The type of patch is defined by its '''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 its PARAM.SFO replaces the old one, consequently its '''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 its 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)
