== Padding == | |||
Padding added at bottom of LIC.DAT file is to make the total size a multiplier of bluray disc sectors, and to protect the laser lens because otherway it is too tiny and so stressing for the laser. | |||

There is a 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). | |||
<strike>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</strike> --> 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. | |||
