Unity Unpacker

Highly experimental Unity unpacker in Node.js.

This is not an universal unity unpacker, but designed for some specific game. If you are going to unpack other game's resource files and other game is using Unity 5.1.2f, it may work. Otherwise, it might not work.

Work in progress.

$ npm install unity-unpacker -g
