(After looking through a few param.sfo's, I noticed that for the "FORMAT" attribute, the param_len is marked as 3, even though if it were a null-terminated string as it indicates by the fmt, it would be then marked as 4. so basically, for param_len I chang)

PARAM.SFO[edit | edit source]

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[edit | edit source]

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.

Internal Structure[edit | edit source]

Header SFO[edit | edit source]

This is the Header of a SFO file.

Offset Data Length Notes
0x00 00 50 53 46 0x04 " PSF" Magic
0x04 01 01 00 00 0x04 Version
0x08 xx xx 00 00 0x04 Key table start offset
0x0C xx xx 00 00 0x04 Data table start offset
0x10 xx 00 00 00 0x04 № of entries in index table 
 typedef struct sfo_header_t {
     int magic; //PSF
     int version; //1.1
     int keyTableOffset;
     int dataTableOffset;
     int indexTableEntries;
 } sfo_header_t;

Index table[edit | edit source]

Starting at offset 0x14, this structure (0x10) is repeated the number of times defined in the header ( № of parameters)

Offset Data Length Notes
0x14 00 00 0x02 Key table offset
0x16 04 0x 0x02 param_fmt (type of data)
0x18 xx xx 00 00 0x04 parameter length
0x1C xx xx 00 00 0x04 parameter max length
0x20 00 00 00 00 0x04 Data table offset 
 typedef struct indexTableEntry_t {
     unsigned int16 keyOffset; //offset of keytable + keyOffset
     unsigned int16 param_fmt; //enum (see below)
     unsigned int32 paramLen;
     unsigned int32 paramMaxLen;
     unsigned int32 dataOffset; //offset of datatable + dataOffset
 } indexTableEntry_t;

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[edit | edit source]

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[edit | edit source]

  • 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.

Parameters Descriptions[edit | edit source]

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