Dynup released Xboxburner v1.0 on our forums, an easy to use burner for XBox and XBox360 game images:

I developed a GUI for growisofs. XBoxBurner burns XBox and XBox360 game images. It runs under Linux, Windows and MacOSX! Current version is: 1.0

XBoxBurner needs the following to run:
- Qt library (4.7 are urgently recommended!)
- growisofs (part of the dvd+rw-tools)

Windows and MacOSX versions are in preparation! I hope, this little app will help you!
Please write me your opinions! New ideas, suggestions, improvements, criticism and other feedback are welcome!
