or if that dont work! which it didnt with me. you can use a little Command line Program called bin2iso which i got at
www.dcemulation.com. (i remembered seeing the program there when i was exploring the crap the Sega Dreamcast can do)
Converts that bin to an ISO which you can burn with Nero or use winRAR to extract the contents of the ISO to your hard disk.
