System File Object (SFO) (PSF)

See also Discussion page

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 Length Param
- [PSF offset] + (0x1C * (0x10*i))
Get Length 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
