Talk:LIC.DAT

Multiboot PS3 Game Discs

There is an special type of PS3 game disc that contains several EBOOT.BIN with several LIC.DAT. These LIC.DAT files are a bit special because contains the TITLE_ID of all the EBOOT.BIN. The first game found using this disc structure was: Metal Gear Solid The Legacy Collection (BLJM-91001 on PS3_DISC.SFB), and the second one: Fighting edition (BLES-02129 on PS3_DISC.SFB)

Total size of the file is always 0x10000, license "slots" starts at 0x800 so... 0x10000 - 0x800 = 0xF800 (available size) and 0xF800 / 0x100 = 0xF8 (available license slots). So the maximun number of bootable contents in a "multiboot disc" is limited to 248 Wrong, the path PS3_GM01, PS3_GM02, etc... only allows for 2 digits... so up to 99 + main bootable content in PS3_GAME makes a total of 100

• dev_bdvd/PS3_GM01/LICDIR/LIC.DAT:
  • The file is the same, only is changed the flag to debug = 0x00000000 (and the crc32 because the flag is included before hash is calculated)
  • This means the file LIC.DAT under directory PS3_GAME is different than any of the others under paths PS3_GM01, PS3_GM_02, etc... (because the flag in main is retail and in the others is debug). But all the others are exactlly the same file because all them have the flag debug
