I just bought an xbox... last week... with a manufacture date of April 22 2005.... I wonder what version it is... I'm not about to open it up just yet - I have to order a nice big hard drive for it...
BTW, eh., I have one of those discs that you have in your avatar... quite an interesting 140KB default.xbe is contained on it, as well as misc data that is hidden to most anyone... (about 6.4 GB worth of data, which seems to be hidden using a special flag in the xbox kernel)... Or so I think.
I used to use some software to backup my PS1 disks.. that software dumps 1:1 raw data of image into hd.. you might try dumping raw data .. Nero has a option like that..
