^^ he's talking about the savegame file, not the game itself. u know what im talking about? the file where he saves his playoffs,or his created players,etc....
just copy the whole nba live 2003 directoy to a cd or something, then install the game on the new computer,then the replaces all the files on the new computer with the files you put on a cd from the old computer,then you dont have to wonder and try to see which file/s u need. that should work
