NoPspEmuDrm is a plugin that allows you to bypass DRM checks on PSP and PS1 games, enabling you to play digital backups of these games or games that you legitimately own but on another PSN account. It is important to note that the developer explicitly states not to use this plugin for piracy.

Features

• Play any PSP, PSX, NeoGeo, PC Engine or TurboGrafix16 contents without a license -- Directly from the livearea, as if you got it from the PlayStation Store, no Adrenaline.
• Use any PSP DLC Content (EDATs) without a license
• Use PocketStation functionality with PSX games that support it. note: requires "PocketStation App" to be installed.
• Start PspEmu content without NpDrm activation
• Force __sce_ebootpbp signature file validation success (means- psp bubbles wont be thanos snapped out of existance upon downgrading or changing accounts)
• Can use any Multi Disc EBOOT.PBP on your vita, even if they are not within __sce_discinfo.

Installation

The installation of the plugin consists of two parts: a kernel plugin and a user plugin. Both need to be installed for the plugin to work correctly. The file paths for the kernel and user plugins are as follow on config.txt:

*KERNEL
ur0:/tai/NoPspEmuDrm_kern.skprx
*ALL
ur0:/tai/NoPspEmuDrm_user.suprx

Installation of PSP Games

To install PSP games, you may need to make additional modifications based on the version of the software you are using. For example:

• If you are using pkgj version v0.55, you need to add install_psp_as_pbp 1 to the config.txt file.
• If you are using nps browser with PKG2ZIP v2.3 or older, you need to add the -p argument to the pkg2zip parameters.

It is important to note that neither VitaShell nor PKGj Vita currently support promoting PSP games. To refresh the live area, you can click triangle on the main screen and select "refresh livearea".

Notes

• This is not an eCFW and will not work with PSX2PSP or Homebrew applications - only offical content. ( chovy-sign / sign_np will work though )
• First time startup of a game may take longer than later runs as it has to find the games decryption key, however it is cached after that and will be faster
• PSP EBOOT.PBP games dont work in adrenaline by default because adrenaline do not patch npumd drm. (can be fixed with npdrm_free psp plugin by qwikrazor however.)
