Unity Unpacker

Highly experimental Unity unpacker in Node.js.

This is not an universal unity unpacker, but only targeting Unity 5.1.2f. I may eventually add supporting code for other versions, but for now it only supports 5.1.2f version.

Work in progress.

Installation

$ npm install unity-unpacker -g
$ # or
$ yarn global add unity-unpacker
