        the white and grey wires are for the power button, while the brown and red are for the exit emu button

          @O-M-A-A I don't think the brown/red are tied to GPIO 7.

          Modify the script and change 2nd buttons's pin number from 7 to 33 and see if you get a different result:

          #!/usr/bin/python
          import RPi.GPIO as GPIO
          import time
          import subprocess
          
          GPIO.setmode(GPIO.BOARD)
          
          # we will use the pin numbering to match the pins on the Pi, instead of the
          # GPIO pin outs (makes it easier to keep track of things)
          # use the same pin that is used for the reset button (one button to rule them all!)
          GPIO.setup(5, GPIO.IN)
          GPIO.setup(33, GPIO.IN)
          
          oldButtonState1 = True
          oldButtonState2 = True
          
          while True:
              #grab the current button state
              buttonState1 = GPIO.input(5)
              buttonState2 = GPIO.input(33)
          
              # check to see if button has been pushed
              if buttonState1 != oldButtonState1 and buttonState1 == False:
                  # shutdown
                  subprocess.call("shutdown -h now", shell=True,
                    stdout=subprocess.PIPE, stderr=subprocess.PIPE)
                  oldButtonState1 = buttonState1
              
              if buttonState2 != oldButtonState2 and buttonState2 == False:
                  # Reset emulator
                  subprocess.call("/home/pi/scripts/multi_switch.sh --es-closeemu", shell=True,
                    stdout=subprocess.PIPE, stderr=subprocess.PIPE)
                  oldButtonState2 = buttonState2

            @mitu didn't work,
            would it be fine if u get access to my computed and try it yourself as maybe the way I'm doing it is wrong.

              Can't do that, I'm sorry.

                @mitu it is okay thank you for your patient,

                I will just summarized what I did so u will have an idea maybe of the mistake I did, when I installed the retropie image, I basically run the link to the script (shudown.py) and this made the power button to work.

                Then I open it with notepad++ and I modified it to install the exit emu button.

                lastly, I downloaded ur file (multi_switch.sh) and executed the command u provided it me.

                for now pins are 3+4 for the exit emu button and 5+6 for the power button.

                  I edited the post - try putting the reset pins (brown/red) on the original position and change the GPIO number from 3 to 33 (or just copy the edited script).

                    @mitu I put the 2 wires back to the same position and I edited the file from 3 to 33, but didn't work

                          I'll try to pull up my Pi to see how the reset button wires are wired on mine, it uses GPIO3, but I'm not sure where the other PIN is connected so that it generates the push event. It might take a while, though, I don't have it at hand right now.

                            As I counted PIN connection on your picture it is likely your wiring is tied to PIN26 instead of 33?

                                @O-M-A-A And if you look to the python code, what do you see? There is PIN33 used for input. Which is obviously not used in your setup? Please change the GPIOinit and buttonState2 to 26

                                Please use the script that @mitu posted!
                                Because he also used the BCM Pin layout as setting which makes things a lot easier to hook up.

                                  I'm not concerned much on the power button, as I'm planning to install a micro usb click button like this one:

                                  61jgjiVkgtL.SL1500.jpg

                                  So I can remove the push button pins on gpio 3 and install the exit emu button instead.

                                    @O-M-A-A The numbering can be done in 2 ways

                                    • pin number (1 - 40) - the inner numbers in your picture.
                                    • so called Board/BCM (?) numbers - the outer labels in your picture.

                                    If you look at how your wiring picture looks like, you see that the power wires are using pins 5 and 6, not GPIO5 and GPIO6. The numbers in your script are the PIN numbers, not the GPIO (outer) labels.

                                      Maybe this will help @O-M-A-A, too

                                      Can use it in GPIO 3 instead of the power button ? and remove the power button wires as I don't need it.

                                      The GPIO is a bit special one. It let's the Raspberry recover/restart from deep sleep mode. So it's very common in use for power off/power on events.
                                      Do use this switch cable to full cut power from the Pie - after Powerdown. But never cut power by force

                                        the exit emu button is on pins 25 and 26 which GPIO 7 I was using

                                        Can use it in GPIO 3 instead of the power button ? and remove the power button wires as I don't need it.

                                          You do need it, because that switch that you want to buy will not shut down properly your PI (i.e. will not run the shutdown command), it will merely cut down the power.
