Editing PS3 DISC.SFB

<div style="float:right">[[Image:icon media ps3 bd.png|200px|thumb|left|PS3 Blu Ray]]<br /></div>
Main file of a PS3 disc, used as a descriptor of the title and contents.<br>
The hybrid flags says to the PS3 to look for [[PARAM.SFO]]'s in specific folders, several flags can be used at the same time

=Internal structure=
The file has a lot of padding, probably to avoid forcing the laser lens to read a file too small. It has big endian byte ordering.

The order of the flags its not clear (is not alphabetically) but there are 32 bytes reserved for them, so probably any combination is valid

=Notes=
<div style="float:right">[[File:Icn-DiscBenefits.png|100px|thumb|center|Icon Disc Benefits]]<br /></div>
*The flag "'''g'''" activates two subfolders '''PS3_GAME''' (main game) and '''PS3_EXTRA''' (one of the 3 ways to include extras in a disc).<br> Games are marked as "'''gu'''" (because there is always an UPDATE.PUP), if you want to remove the folder '''PS3_UPDATE''' is good to remove the flag "u" from here
*The flags "'''T'''" and "'''V'''" activates subfolders inside '''PS3_CONTENT''' (the second way to include extras in a disc)
*The third way to include extras in a disc depends of "'''g'''" but its needed to activate another different flag in TITLE_ID\'''PS3_GAME'''\[[PARAM.SFO]] (in his ATTRIBUTE parameter)
*The flag '''"S"''' appears (need to remove-insert disc on top of BD-EMU) with games featuring Cross Buy (FW 4.25+?), and will load the icon "Disc Benefits" (dev_flash\vsh\resource\explore\icon) and [http://www.ps3devwiki.com/wiki/File:Xmb-contentinfo-sd.png pic].<br> This flag might only concern [[PSVita]] content. [[Talk:PARAM.SFO#TITLE_ID | Specific title id]] as XCJS-0000* is not required. Order is : "gSu".
*Other flags ?: See {{talk}} page.
