When you insert a physical Blu-ray game disc, the console reads this file from the LICDIR (License Directory) folder to validate the software. Without a valid lic.dat file matching the specific Title ID of the game, homebrew backup managers like multiMAN, IrisMAN, or WebMAN MOD will fail to boot the game, resulting in errors like the infamous "An error occurred during the start operation (80010017)." Why Do You Need to Generate a Lic.dat File?
The backup manager will analyze the game directory. If it detects a missing license structure but a valid PARAM.SFO , it will automatically generate the required parameters or prompt you to convert the folder into an ISO file—which inherently bypasses individual LIC.DAT checks by emulating a real disc structure perfectly.
