I originally was trying to use PS3ISO Tools v2.1 but couldn't get it to work to save my life, it kept renaming my game folder then giving me an error message and closing. So I switched to GenPS3ISO (read that it was recommended by the Rebug team or something like that) and seemingly worked fine but asked for an IRD file.
I began looking into what an IRD file is and that lead me to a program called
PS3 ISO Rebuilder (which apparently also creates an ISO).
PS3 ISO Rebuilder wants me to "change certain files to the original" and I have no idea what to do. The red lines for UPDATE's seem easy enough but I want to ask...
Do I REALLY need to install the UPDATE file and change the yellow lines to the original files? Or can I just use
PS3 ISO Rebuilder to find the IRD file then go to GenPS3ISO and make the ISO without the UPDATE PUP and without changing files to the original (which I have no clue how to do)?
Any insight into this would be greatly appreciated, thank you.
