It uses a bin format that needs processing to get the nb0 file.
I wrote a tool to convert the bin file into nb0 file. However it does not have the function to convert nb0 back to bin because of the complexity.
The converter can be downloaded at http://www.mediafire.com/upload_comp...id=pilqms9mmbx.
Usage: p320bin2nb0 <bin_file>
After successful conversion, the resulting file is output.nb0, which can be processed by using imgfsfromnb or msflshtool.
