Samples: [[param.sfo/samples]]

'''SFO''' ('''S'''ystem '''F'''ile '''O'''bject) file format can be also found on [http://www.psdevwiki.com/ps3/Eboot.PBP#PARAM.SFO PSP], [http://www.psdevwiki.com/vita/index.php?title=System_File_Object_%28SFO%29_%28PSF%29 PSVITA], [http://www.psdevwiki.com/ps3/PARAM.SFO PS3]. This page, as well as talk page, is mostly speculation about this [[Content_Information_Files|content information file]].

The values contained in a parameter (other naming: key) of the SFO can be simplified as inputs/outputs for/from the content:
*Boot modifiers (flags).
*Information texts.
=== External Structure ===
Speculation about the Container wrapping the Data of the param.sfo File (only on disc?)

*length: 0x800 always?

*or first chunk starting at 0x38, ending at 0x208.

==== Key table ====
Ordered alphabetically, each name of parameters of this table is NULL terminated with 1 blank byte (0x00) to separate them. 

The table has padding at the end to align their size to a multiply of 4 ( if matches with a multiply of 4 this padding doesn't exist) 

==== Data table ====
*UTF-8 entries never uses all the reserved bytes, needs 1 blank byte (0x00) after the last character.

*Integer entries uses all the reserved bytes.

*'''Flag №2''' {{padcross}} / {{padcircle}} button assignment can be set per title using the param.sfo - it is however recommended to not deviate from the system standard as set per region/country. Without a value set, it defaults to the system standard.
*'''Flag №16''' CPU mode must be 6 CPU mode if extra USB Audio devices are used
*'''Flag №27''' The Application Requires PlayStation VR: By removing it, you can bypass (some games only?) the requirement of connecting the PSVR and experience a PSVR game without the VR.
