Binmap Logo Binmap (experimental)

A tool that helps to analyse and document binary data files/formats. It can also be used to edit values and write back changes, just like a regular hex-editor but does not allow to insert or delete bytes. All UI controls of this application are custom-made for fast rendering and style.


start screen:

Binmap start screen

data loaded, unformatted; all bytes are formatted in hex by default:

data formatted and commented:

How it works and what it does

Drop any file into Binmap to load its data. Binmap shows all bytes in hex format by default. The format of each byte can be changed by selecting single bytes or ranges and clicking the respective format button. Line-breaks can be entered by hitting the ENTER key and can be removed again with the BACKSPACE key. Each section can be commented.

Binmap saves all modifications to a .binmap file which also contains the data file name. If a .binmap file exists, Binmap loads and applies it right after the new data file is loaded. In addition, .binmap files can be double-clicked or dropped into Binmap to load the data file and immediately apply the formatting.

Source Code

Binmap is a .NET application using XNA/MonoGame/SharpDX (Visual Studio Community 2015 solution) for fast rendering on the GPU. The dll overkill feels a little weird but I wanted to see how it performs for UIs. The font in use is called Pixel Operator and should be installed for compiling.
