A GUI that allows batch decryption of NPDRM encrypted PS Vita titles.

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.
    • Full control over the content you own.

User guide

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.

How to use

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 PS Vita (not inside ux0:app).
    • (VPK) Open VitaShell and install the package.
    • (Folder) Open VitaShell and press Triangle on the app folder and choose M > 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.
