Where are the L3 and R3 buttons on a PS2 controller?
the l3 button is the analog stick that moves on the same side as the l1 & l2 buttons & the r3 button is the analog stick that moves on the same side as the r1 & r3 buttons which them selves are located at the back of the controller not on the underside though if you press the anlog sticks you will hear them click
