Internal Structure

The values contained in a System File Object 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).

Header SFO

This is the Header of a SFO/PSF 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 (params/values) 
typedef struct{
    int magic; //PSF
    int version; //1.1
    int keyTableOffset;
    int dataTableOffset;
    int indexTableEntries;
} sfo_header_t;

Index table

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{
    u16 keyOffset; //offset of keytable + keyOffset
    u16 param_fmt; //enum (see below)
    u32 paramLen;
    u32 paramMaxLen;
    u32 dataOffset; //offset of datatable + dataOffset
} indexTableEntry_t;

Used on index table, there are 3 variables:

0x6+0x10*i
(i=0,1,2,3,4,5,...)

Param_fmt Arch Format Notes
04 00 Little Endian utf-8 Special Mode Used in contents generated by the system (e.g.: save data)
04 02 Little Endian utf-8 Character string, NULL finished (0x00)
04 04 Little Endian 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.

Algorithm

(i=0,1,2,3,4,5,...)

  • Get Position Value
    • [PSF offset] + [Value Start] + (0x14+(0x10*i))
  • Get Type
    • [PSF offset] + (0x16 * (0x10*i))
  • Get Lenght Param
    • [PSF offset] + (0x1C * (0x10*i))
  • Get Lenght Value
    • [PSF offset] + (0x24+0x10*i)-(0x14+0x10*i)
  • Get Position Param
    • [PSF offset] + [Param Start] + (0x20+(0x10*i))

for any problems, you can give a look into my sourcecode: sfo_stuff.c
