PARAM.SFO

See also Discussion page

Samples: param.sfo/samples

SFO (System File Object) file format can be also found on PSP, PSVITA, PS3. This page, as well as talk page, is mostly speculation about this 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.

Used on index table, type of data are:

param_fmt	Format	Notes
04 00	utf-8 Special Mode	Used in contents generated by the system (e.g.: save data)
04 02	utf-8	Character string, NULL finished (0x00)
04 04	integer	32 bits unsigned

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 №1The application does not support the initial user's logout is set per default.
• Flag №2 / 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.
