+Place npdrm_free.prx in ms0:/seplugins/ and enable it in vsh.txt.
+Restart VSH, now you can launch any official EBOOT.PBP without a license.
+
+If a license is not found then a fake one will be created, otherwise the official license will be left alone.
+
+If flash2:/act.dat is not found then a fake one will be created.
+
+To allow PC Engine games to run, either enable the nodrm engine in Pro CFW or install nploader.prx and enable in game.txt.
+
+Game software manuals that require a license will now work without a license using this plugin enabled in vsh.txt.
+
+Licensed DLC should now work and should now be 6.20 compatible.
