The PSVita NPDRM Decryptor is a program that allows you to decrypt NPDRM encrypted PSVita titles. NPDRM is a type of encryption used by Sony on their PSVita games and apps. By decrypting these files, you can play them on your PSVita without needing a plugin like NoNpDrm Vita.

Features

Straightforward GUI to decrypt NPDRM protected apps/patches/addcont:
- Easier modding
- Allows all apps to run on all firmware versions
- Removes the need of plugins like NoNpDrm Vita
- Full control over the content you own

Software Requirements

Microsoft Windows 7 or later (x64)
.NET Framework 4.8.1
(Optional) "TrialPatch" user plugin to bypass game trials (e.g. Rayman Legends, FEZ)
(Optional) "rePatch-reLoaded" kernel plugin to install patches & addcont without merging

Usage

If you have a PKG file and not a NPDRM app in folder format you'll first need to extract the PKG with "pkg2zip.exe" or similar by providing the correct zRIF.

Use the + button or drag & drop encrypted folders, select the output directory and click the blue arrow
Adjust the options in the checkboxes to your liking
Remove highlighted folders with the X button

Follow the Input Folder Search Structure section below to setup your input folders correctly with patches and addcont.

The program will search for patches/addcont only when decrypting the main app with the specified folder setup.

Patches and additional content can still be decrypted separately.

Installing decrypted applications

App
- Copy the VPK/folder to the PSVita (NOT inside ux0:app)
- (VPK) Open VitaShell and install the package
- (Folder) Open VitaShell and press △ on the app folder and choose More -> Install folder
- Accept extended permissions
Patch
- Merge with main app or use rePatch
Additional content
- Use rePatch

For now app installation must be done through VitaShell because we need to generate a fake head.bin to display the app in the livearea.

Installing decrypted applications (rePatch)

App - Install as described before
Patch/Additional content
- rePatch-reDux0 Wiki

Troubleshooting

"My app says it's a trial"
- Install the "TrialPatch" plugin.
"DLCs don't work"
- Install the "rePatch-reLoaded" plugin.
"I can't install the decrypted app, VitaShell throws and error"
- Delete the NPDRM version. If that doesn't work, manually delete the folders with the TitleID of the game in ux0:app, ux0:patch, ux0:addcont, ux0:appmeta and reboot.
"The program doesn't recognize a patch folder"
- If you are trying to decrypt a single patch without the main app in the structure described above, you'll need to copy the original work.bin of the main app (app\sce_sys\package\work.bin) and place it inside the patch folder: patchTitleID\sce_sys\package\work.bin. Additional contents have their own work.bin, so you don't need the original one for DLC decryption.
"Some apps decrypt incorrectly / don't function properly"
- Open an issue and I'll look into it, some apps are known to cause issues.

TODO

Add proper support for gdc apps (e.g. Reader™ [PCSC80012])
Make VitaShell's Refresh livearea work on decrypted apps
