# NoPspEmuDrm:



A plugin to bypass all PSPEmu DRM Checks,

so you can play digital PSP or PS1 game backups; or of course- games you legitimately own but on another PSN Account



Defintely do not use this for piracy that would be bad mmkay?



Okay, now that message to keep the lawyers happy is out of the way --



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 game on your vita, even if they are not within \_\_sce\_discinfo. 

# Installation:

The plugin consists of two parts; a kernel plugin and a user plugin;

both need to be installed for it to work correctly;



the config.txt entries you need are:



```

*KERNEL

ur0:/tai/NoPspEmuDrm_kern.skprx

*ALL

ur0:/tai/NoPspEmuDrm_user.suprx

```



# Installation of PSP Games:



----



There is now a build of PKGJ that supports background downoload of PSPEmu contents 



https://github.com/blastrock/pkgj/releases/tag/v0.57



Please let us know if you have any issues with this !



----

Manual Install:



Copy digital PSP/GAME folder to ux0:/pspemu/PSP/GAME



however crrently, VitaShell not support "Promoting" PSP games



However i have a fork of VitaShell that adds this in:



https://github.com/KuromeSan/VitaShell/releases



and on the main screen click triangle, press "refresh livearea"



----



( if you use pkgj version v0.55 you need to add `install_psp_as_pbp 1` to the config.txt )



( if you use nps browser with PKG2ZIP v2.3 or older; you need to add `-p` argument to the pkg2zip parameters )



----



# Note:

- this is not an eCFW and will not work with PSX2PSP or Homebrew applications - only official 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 and will be faster



- Game manual will only work after first time run in some games as it looks for the cached keys ..



- Aderenaline compatibility: 

PSP EBOOT.PBP games dont work in adrenaline by default because adrenaline does not patch npumdimg drm. (psx games should work fine however)

..

so to be able to use psp EBOOT games with adrenaline youll need to install the [npdrm_free](https://github.com/qwikrazor87/npdrm_free) psp plugin by qwikrazor.

..

this is not needed if you dont use adrenaline

Hykem      - kirk_engine, used to "emulate" alot of the KIRK security co-processor functions from the PSP.



SquallATF  - Wrote alot of the Chovy-Sign2/PspCrypto code that this is heavily based on; Also helped with EDAT. 



TheFlow    - Original NoNpDrm code- NoPspEmuDrm_kern is fork of NoNpDrm.

             and for the original Adrenaline v3.00, which i think i copied like 1 function from

			 which was for reading/writing to PspEmu memory,
