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.

Installing decrypted applications (rePatch)

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

-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]].

 == Troubleshooting ==
-* &quot;My app says it's a trial&quot;
+[https://github.com/SuleMareVientu/PSVitaNPDRMDecryptor/blob/main/README.md#troubleshooting Troubleshooting on readme.]
-** [https://www.gamebrew.org/wiki/TrialPatch-PSV_Vita Install the &quot;TrialPatch&quot; plugin.]
-* &quot;DLCs don't work&quot;
-** [https://www.gamebrew.org/wiki/RePatch_reLoaded_Vita Install the &quot;rePatch-reLoaded&quot; plugin.]
-* &quot;I can't install the decrypted app, VitaShell throws and error&quot;
-** Delete the NPDRM version. If that doesn't work, manually delete the folders with the TitleID of the game in <code>ux0:app</code>, <code>ux0:patch</code>, <code>ux0:addcont</code>, <code>ux0:appmeta</code> and reboot.
-* &quot;The program doesn't recognize a patch folder&quot;
-** 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 <code>work.bin</code> of the main app (<code>app\sce_sys\package\work.bin</code>) and place it inside the patch folder: <code>patchTitleID\sce_sys\package\work.bin</code>. Additional contents have their own <code>work.bin</code>, so you don't need the original one for DLC decryption.
-* &quot;Some apps decrypt incorrectly / don't function properly&quot;
-** Open an issue and I'll look into it, some apps are known to cause issues.
-== TODO ==
-* Add proper support for <code>gdc</code> apps (e.g. Reader™ [PCSC80012])
-* [https://github.com/TheOfficialFloW/VitaShell/blob/master/package_installer.c#L222 Make VitaShell's <code>Refresh livearea</code> work on decrypted apps]
