if u have a v9 u can get a matrixml or smart chip or magic V 50k or if u plan to get the hard dirve i would go with dms3 which is what i have and it has a flash that well be out soon to allow ur hd to work with the modded unit so far thats the only chip that has hard support but all those chips will play this game
