NPloader (DLC loader) - codestation

Modified by lusid1 with encrypted DLC handling code by qwikrazor87

This plugin allows direct reading and loading of DLC (EDATA/PGD/SPRX) files in either 
their encrypted or decrypted form, so you don't need to reactivate your account and/or 
switch between them while using your purchased DLC from different regions. You can mix 
decrypted/encrypted files without problem too, the plugin takes care of that.

Instructions:

Copy the plugin in the seplugins folder and enable it in game.txt using the following
line: ms0:/seplugins/nploader_mod.prx 1

Tested on CFW from 5.00 to 6.60 (Pro CFW is recommended).
Mod tested on 6.61 ARK and 6.61 Pro.

New in 0.8:
Now you can place your DLC folders in a custom location (useful if you don't want to fill
up your xmb menu with content that you aren't gonna launch). To do this create a file named
nploader.ini (or use the file provided) and add/edit the path where you are gonna move
your DLC folders. Example: ms0:/PSP/DLC
Note: remember to add a newline to the end of the file.

Important: the redirection is only for DLC files, if you have another content that is using
the DLC folder (e.g.: game updates), then these files must remain in that directory
(e.g.: the *ARC patch files from the LBP update).

Known issues:
Do not mix with the noDRM implementation of Pro CFW. If you are using one of them
then disable the other.
Do not mix with the npdrm_free plugin. Use the npdrm_free_mod plugin instead.

Changelog:
v1.1 MOD:
      Improved DLC folder redirection compatability
      Skip DLC redirection when the file does not exist at the custom DLC location.
v1.0 MOD:
      Added support for encrypted DLC

      Skip opnssmp module when is loaded.
      Released source code.
v0.6: Added all the incarnations of the Prometheus loaded to the module blacklist
      so the plugin doesn't make the mistake of hooking to those. This fix will

      is gonna to be included in a future release.
