I'm not positive, but in Xport, it goes in the same location as the .ROS file
Added a 2nd download link for the Official Roster on Megaupload, if anybody has any problems with any of the links let me know and i'll provide an alternate. Also, i don't keep up with every single Roster on the boards, so if there is an update to a certain roster, just let me know and i'll get on it.
If somebody could make a short tutorial on how to add the roster files to their hard drive for the people that might not know how to do it, that would be great. Do people absolutely need the transfer kit? or is there a way to get it on a xbox 360 formatted usb drive first, and then copy over to main hard drive ? I notice that there is a USB Xplorer for the 360
