they dont appear in the games section of avalaunch but they Do appear in Evox ?!
if thats the case, then i dont have a clue.
if it's not, then make sure that the game files are in folder in the games section:
games -> NBA Live -> game files.
i've had it wrong several times by doing it like this:
games -> NBA Live -> NBA LIVE 2005 -> game files.
Just make sure there installed correctly, game loading from subfolders doesnt work.
