C'est à utiliser conjointement avec ReactPSN.
It is based on a my own research.
Place it to the ps3tools directory along with other tools and then place your idps and act.dat files to appropriate folders.
This tool will generate .rif file that you should copy to your exdata/ folder. Then you can unself a corresponding NPDRM file.
Have fun.
