== Internal Structure ==
The values contained in a '''S'''ystem '''F'''ile '''O'''bject 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.

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

=== 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,...)<br />
*Get Position Value<br />
**[PSF offset] + [Value Start] + (0x14+(0x10*i))
*Get Type<br />
**[PSF offset] + (0x16 * (0x10*i))
*Get Length Param<br />
**[PSF offset] + (0x1C * (0x10*i))
*Get Length Value<br />
**[PSF offset] + (0x24+0x10*i)-(0x14+0x10*i)
*Get Position Param<br />
**[PSF offset] + [Param Start] + (0x20+(0x10*i))

=====Notes:=====

*info bar (top screen):
You can check the status of your PS Vita system on the info bar.

PS Vita system-communication status - Active applications - Audio output status - time -Remaining battery charge

*Communication zone/ activities:
Move the screen down to reveal the communication zone.

====ATTRIBUTE2====

This parameter can not exist on some PKG (used for special functions??)

ATTRIBUTE2 is speculated to be sorted before ATTRIBUTE_MINOR

Speculation and some features could have been removed.
