bdiff

A(nother) binary diff tool, targeted toward decompilation and modding projects.

Features

• Automatic reload of opened files on change
• Pairwise byte diff display (vbindiff style)
• String, data viewer for various formats and encodings
• Support for displaying symbol information from binaries by parsing .map files via mapfile_parser

bdiff is currently in the very early stages of development. See the issues for planned features.

Why?

There's a million other hex viewers out there. Most people in the game decompilation scene use vbindiff, a very dependable but somewhat feature-sparse tool. Over the years, I've started wishing for little things here and there that I wish it could do, and I've also been looking to learn Rust.

Configuration

To provide a more convenient experience, projects can specify a "bdiff.json" configuration file which defines a workspace configuration for the program. An example config follows:

{
  "files": [
    {
      "path": "C:\\somethin.z64",
      "map": "C:\\somethin.map",
    },
    {
      "path": "C:\\another.z64",
      "map": "C:\\another.map",
    }
  ]
}

So far, the configuration format simply consists of a list of files to open (files).

For each file, there are two fields:

• path: The path to the file
• map (optional): The path to a GNU ld or Clang lld .map file, to be parsed so symbol information is displayed in the viewer
