The Famous D-Pad as we now know it, could had been alot different!
Nintendo is credited with inventing the 'famous D-Pad', that replaced the original Arcade 'JoyStick', but between the death of the JoyStick and the birth of the D-Pad, there was one attempt that failed, which was nicknamed the 'boob shaped controller'.
So the next time to pick up your Nintendo gamepad, just remember it could had been alot different what you are playing with in your hands, but us old-timers will remember grabbing the two breasts on the GOTCHA! Arcade cabs from Atari, alot of laughs that one got!
