i'm trying to get the starters from r/b and g/s plus larvitar through my gba action replay. i was able to get lugia and mewtwo but other codes didn't work. i need help. do gameshark codes work on action replay? every code i've tried except some action replay codes that helped me get lugia and mewtwo worked. the others don't.

please help!
