NPdecrypter (EDAT/PGD/SPRX decrypter) is a plugin that is capable of decrypting your legally owned DLC files from games so you don't need to reactivate your account and/or switch between them while using your purchased DLC from different regions.

After your files are decrypted you can load them with NPloader or the noDRM engine of 6.20/6.35/6.39 PRO.

Installation

Copy the plugin in the seplugins folder and enable it in game.txt by adding the following line

ms0:/seplugins/npdecrypter.prx 1

Note: If you are on 6.20/6.35/6.60 PRO, disable the noDRM engine.

User guide

Load the game and it will freeze and start decrypting the DLC (check for the intermitent MS light), note that it takes some time like 2-5 mins per 5 MiB DLC.

When is completed then the game will continue. Now you can exit the game and check the /DLC/ directory, it must contain a copy of your DLC folder in their decrypted form.

Note from developer:

Some games doesn't initialize the npdrm right away, so you must do some action that triggers the DLC load (e.g. GEB loads the DLC after the save load).

Also some games load DLC from another GAME_ID, for those cases one must rename the directory to match the game ID of the game before attempting decryption (e.g. Rock Band Lite).

Remember to disable the plugin once completed because it could interfere with other games or plugins.
