get the most up to date version of xport , and if ur cable comes with a disc ( from microsoft) DO NOT USE IT ! the 127 agression is on the enhancement pack ..
http://www.geocities.com/o_nfl2k_o/ .... but im not sure how to install it yet, other than that just follow the directions exactly and it all worked for me, roster/franchise , editor , stadium music etc. FYI im using xport v2.08 , MS transfer cable , 20 GB HD , XP SP2. Extra note: when doing the stadium music remove the FFFE0000 from your HD and then drag your custom "fffe0000" iin.
