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.

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

Input Folder Search Structure:

├───addcont │ └───TITLE_ID │ │ └───DLC_FOLDER ├───patch │ └───TITLE_ID ├───app (any name or TITLE_ID) │ └───eboot.bin │ └───...

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
