BinaryFileEditor

Binary file editor, patcher

Currently functionality of this application is very limited, but you should be able to replace any gif/mp3/jpg/wav/png/bmp or text in your binary file (ie. firmware).

Sometimes app can found file which is only very similar to known images/sounds formats, but in fact it is just a random bytes array.

This app is just a prototype! Code is not clean, optimal nor final.

This app is using DataStream.js library from: https://github.com/kig/DataStream.js/blob/master/DataStream.js

I've only added "skip" function.

/**
  Skip the DataStream read/write position.

  @param {number} length Bytes to skip.
  @return {null}
  */
DataStream.prototype.skip = function(length) {
  if (this.position + length > this.byteLength || this.position + length < 0) {
	throw new Error('Out of bound!');
  }
  this.position = this.position + length;
};
