thats right, it was only a matter of time before a simple firmware change made the 360 play backed up software.
some clever people who "hang out" at
http://www.xboxhacker.net/
managed to change the firmware on a new 360 so that it would provide the needed responces from the CR protocal ( security software on the disks) this means that in theory if you could obtain the responces needed from other games then you could effectivly backup any game for the 360.
the firmware update also opens up the field for new desktops like the old evox to be installed thus allowing for the 360 to realy flex its muscles.
so in the next few months expect alot more work-arounds to be released for the 360.
