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
Internal structure
The file has a lot of padding, probably to avoid forcing the laser lens to read a "too tiny" file

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 | Unknown | TITLE_ID\PS3_GAME\PKGDIR\PARAM.SFO? |
| 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 |
- 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" appear with Cross Buy games (FW 4.20?). Order is : "gSu". In one example, the game structure is also with PKGDIR and the title id at 0x220 is the same title id than the param.sfo (DP).
