Light.vnTools

Overview

Light.vnTools is an unpack/decrypt and repack/encrypt tool for game made with Light.vn (Visual Novel) game engine.

Requirements

• .NET 7.0 SDK / .NET 8.0 SDK

Usage

Important

The "new" encryption scheme that works on the newer Light.vn version is stripping the original file name, so I can't recover it.

We're missing the original file extension, but we can guess it by reading the file header and set the extension based on that,

For the time being you need to do it yourself by grabbing a hex editor program like ImHex, find the magic header, do some Googling then rename the file.

• Download Light.vnTools at Releases.
• Unpack/Decrypt:
  Drag and drop .vndat / .mcdat file(s) to the LightvnTools.exe.
• Repack/Encrypt:
  Drag and drop unpacked folder/file(s) to the LightvnTools.exe.
