NoPspEmuDrm Vita

A plugin to bypass all PSPEmu DRM Checks, so you can play digital PSP or PS1 game backups.

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. (Requires "PocketStation App" to be installed.)
Start PspEmu content without NpDrm activation.
Force __sce_ebootpbp signature file validation success (means that PSP bubbles won't be snapped out of existence upon downgrading or changing accounts).
Can use any Multi Disc game on your Vita, even if they are not within __sce_discinfo.

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

How to install PSP game:

Copy digital PSP/GAME folder to ux0:/pspemu/PSP/GAME/.
Note that currently, VitaShell not support "Promoting" PSP games, you can use the author's fork that supports this.
And on the main screen click Triangle, press "Refresh LiveArea".

Notes:

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 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).

NoPspEmuDrm Trailer - (Silica)

v1.06

First tries the last PBP or EDAT file to be opened, before scanning the whole /PSP/GAME folder, should hopefully speed up launch times if you have alot of games installed.
Improve detection for if you have NpDrm activation or not, hopefully.
Cleanup the code a bit, shouldn't have too much of an impact on things.

v1.05

Now reads ConsoleID for rif generation from idstorage, this should hopefully fix compatibility issues with Console ID Spoofers.

v1.04

Fixes a bug where games with data.psar file larger than 2,147,483,647 bytes would not work.

v1.03

v1.02

Fixes a rare bug in some games that would reboot the entire psp kernel at runtime, causing NpDrm.prx patches to be removed (ex; The Power Stone Collection).
Fixes a bug with parsing rif start and end dates, in offical rif files.

v1.01

Fixes a bug where cached rif would not be re-generated if was generated without activation and then you activated your console.

v1.00

Li - Main dev; wrote all plugin code (except crypto/), Being transgender.
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.
