PS3 DISC.SFB
Main file of a PS3 disc, used as a descriptor of the title and contents.
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
[edit] Internal structure
The file has a lot of padding, probably to avoid forcing the laser lens to read a "too tiny" file

[edit] Hybrid Flags
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
| Hex | ASCII | Description | Path |
|---|---|---|---|
| 53 | S | Benefits | Unknown |
| 54 | T | THEME | TITLE_ID\PS3_CONTENT\THEMEDIR\PARAM.SFO |
| 56 | V | VIDEO | TITLE_ID\PS3_CONTENT\VIDEODIR\PARAM.SFO |
| 67 | g | GAME & EXTRA | TITLE_ID\PS3_GAME\USRDIR\PARAM.SFO & TITLE_ID\PS3_EXTRA\PARAM.SFO |
| 75 | u | UPDATE | TITLE_ID\PS3_UPDATE\UPDATE.PUP |
| 76 | v | BDMOVIE | TITLE_ID\PS3_VPRM\PARAM.SFO |
[edit] Notes
- The flag "g" activates two subfolders PS3_GAME (main game) and PS3_EXTRA (one of the 3 ways to include extras in a disc)
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 with games featuring Cross Buy (FW 4.25+?), pic and icon used fo this structure (dev_flash\vsh\resource\explore\icon) might only concern PS Vita content but the message displayed is undefined.
Activate "Disc Benefits" (from BD emu: remove-insert again disc). Order is : "gSu".
In one title, the game structure is also with PKGDIR but it s not related ("S" flag is the only requirement for this structure). Specific title id as XCJS-0000* is not required to load this structure.
