      Hi All

      This is my first time doing a pi project & as well as posting here.
      I tried a lot googling but most show cases dont have this issue.
      My 3.5" LCD screen is using GPIO pin for input & power. Product pic (back of LCD screen) as below:

      Are there any other way for me to connect a gameboy gamepad not using GPIO? or anyway?

        @mattchoo Your screen likely doesn't need all of those pins to operate. My Sainsmart (Waveshare clone) 3.2" only needed a handful of pins to work even though it had a 26 pin connector. I had to take the display apart to remove the connector anyway, so when I did so I only connected up the necessary pins.
