What is it?
Simply put, - XBXTools will extract an xbx file to a dds file.
- XBXtools will build an xbx file from a dds file (or Jpg File).
- Acts as Bundler.exe(MS SDK) and xprectract2.exe.
- No painful cmd line interface anymore. Only 2 buttons - Extract/Build.

Notes:
*Jpg in "Build XBX" is only there for xboxlogo.xbx, Build all other XBX files from DDS.
*Save dds files as dxt1 with no mipmaps in photoshop, or your dds editor.
