npdrm_free_mod

by qwikrazor87, modified by lusid1

A PSP/ePSP plugin to run official NPDRM PS1/PSP content without need of a valid .rif license or act.dat.

Usage

• Place npdrm_free_mod.prx at ms0:/seplugins/npdrm_free_mod.prx.
• Enable plugin in both ms0:/seplugins/game.txt and ms0:/seplugins/vsh.txt.
• Write this line in both .txt files: ms0:/seplugins/npdrm_free_mod.prx 1
• Restart VSH, now you can run any official PSN content without a license.

ALL content MUST be encrypted and left as is from official .pkg for this plugin to work, otherwise use NoDRM engine in PRO CFW.

NOTE: This modified version will not load DLC on its own. It is intended to be used in conjuction with nploader_mod which now supports both encrypted and decrypted DLC.

Changelog

v7.3 (MOD)

• Disabled loading of encrypted DLC to avoid crashing when used with nploader_mod

v7.2

• Suspend/resume issue should be fixed, thanks to kyleatlast.

v7.1

• Fixed the import scanning function that caused a crash on false positives.

v7.0

• This plugin now patches the core of npdrm to decrypt content if and only if the official method (rif + act.dat) fails
• Now you can run official PSN games and DLC without needing to decrypt them.
• Now generates KEYS.BIN for official PSN PS1 EBOOTs on-the-fly if needed.
• PSN TG-16/PC Engine games can now be run without first decrypting any content, do NOT decrypt the PSP-KEY.EDAT for it.
• PTF themes requiring a license can now be installed.
• Suspend issue from previous versions should now be fixed, if not try disabling all other plugins.

Credits

Huge thanks to all involved in the PSP/ePSP/PSVita homebrew community, devs and users alike, without whom I would not be able to accomplish this task. You are too numerous to name.

Big thanks to kyleatlast who revived this project by finally fixing the suspend issue in ePSP.
