SPECIFICALLY, JUST TELL ME WHAT THESE BUTTONS DO:
(RT, RB, LT, LB),
( A;B;X;Y),
(FOUR MORE BUTTONS ON OTHER SIDE),
(TWO THUMB STICKS),
(BACK; MODE; START).
JUST TELL ME THE USES OF THESE.
As for the TURBO button, it relieves us of the burden of having to repeatedly pressing a single button, by keeping it pressed all the while, with the TURBO mode on. basically it acts as a cruise control for the gamepad LMAO
