How to use update & DLC in rpcs3?

Game may install itself to a folder named with a different Game ID for some reason, this may perfectly happen and is entirely up to the game.

It's as simple as if you're ripping the game from the PS3 copy paste the whole install directory to PC after installing the DLCs on your PS3, if you're installing them from packages just install the package and that's it.
Obviously, you have to use DLCs made for the same version of the game that you have, which is BLUS31572.

Paths for DLCs and Updates are entirely game dependent, but if you don't have them as packages then take note of the directory they were into before grabbing them off your PS3.

This is an update for BLUS31572.after installing it doesn't load in rpcs3.
can you try or tell me how to use this update.

the update creates two eboot files in BLUS31572 directory. rpcs3 loads the old version.
