NCAA Tuners were a disaster when coupled with patches & EA Online Pass, because the tuners were released simultaneously with patches and they were meant to work in tandem... The problem was for people without EA Online Pass, because the two things worked together, it legitimately broke the game for anybody who didn't have EA Online Pass... the only way to make the game playable was to disconnect from XBL / PSN, and delete all updates whenever you wanted to play NCAA.
As far as I know, EA never rectified this ridiculous issue, nor even recognized it.
