      I am late to the game here but if my script works as intended (minus saving metadata which was never implemented) and cypherghost's script is not seeing the button presses then the logical thing would be to compare the two scripts and see how they are being handled differently.

        @yahmez ;)
        Thank you for stepping in my friend.
        So let's compare ;)

        #!/usr/bin/python
         
        import RPi.GPIO as GPIO
        import os, time
         
        GPIO.setmode(GPIO.BCM)
        GPIO.setup(23, GPIO.IN, pull_up_down=GPIO.PUD_UP)   #Reset switch
        GPIO.setup(24, GPIO.IN, pull_up_down=GPIO.PUD_UP)   #Power switch
        GPIO.setup(25, GPIO.OUT)                            #ON control
        GPIO.output(25, GPIO.HIGH)
         
        while True:
          if (GPIO.input(24)):
            time.sleep(0.25)
          else:
            print ("Shutting down...")
            os.system("sudo shutdown -h now")
            break
          if (GPIO.input(23)):
            time.sleep(0.25)
          else:
            print ("Resetting...")
            os.system("sudo reboot now")
            break
        

        and

        script version from here
        I did not implent reset handling here ;)

          @cyperghost Maybe the wires are connected to other pins ?

            @mitu This can only be answered by @Semper-5 but I assume not!
            As I remeber he told me, that the python scripts are working ;)

              If it just cuts power upon turning off the power switch it means that the on control pin is not going high on boot.

                  @yahmez Can you test the script on your build, too?
                  @mitu Python is very cool - indeed. But I also checked the way GPIOs are called. It's BCM mode. So Python GPIO = Bash GPIO

                    @cyperghost I will give it a try this weekend if I can but I have relatives coming to stay so I'm not 100% sure I'll be able to till next week.

                      Can you try gpio readall to verify that the on control pin is high?

                          @cyperghost I am no coding guy. Does your BASH script enable the internal pullup on 25?

                            @yahmez No! I don't use wiringpi.... or raspi-gpio.

                            But would be possible with bash, too

                            raspi-gpio set $trigger_pin ip pu
                            echo "monitoring BCM $trigger_pin"
                            
                            pin_state() {
                                raspi-gpio get $trigger_pin | grep -c "level=0 fsel=0 func=INPUT"
                            }
                            
                            shutdown_trigger() {
                                if [ `pin_state` = 1 ]; then
                                    echo "BCM $trigger_pin asserted low"
                            ....

                              @cyperghost That is the problem then, at least part of it.

                                @yahmez afaik this should work without the pullup. As I said, I sadly have no POLOLU switch available. Is there no connection to ground from the POLOLU to the GPIO?

                                  sorry for the late reply. I'm trying to get out of work.
                                  my GPIO config is exactly as configured in Yahmez's tutorial.
                                  23 reset
                                  24 power
                                  25 power (ON)

                                  my GPIO readall with cyperghost's script
                                  but as we see here, its not looking very live.

                                  just as a reminder, I can get Yahmez's to fire up with no problem - just to rule out the possibility of bad wiring and I did confirm that my wiring looked good to a few other people who are VERY familiar with this mod.

                                  EDIT: SORRY I didn't run the gpio readall with the script running. GPIO 25 has a difference now

                                    @cyperghost No. It will absolutely not work without the pullup. There is a reason I put it in my script :p

                                      @semper-5 Why is GPIO25 set low? Okay corrected now.
                                      @Yahmez Okay, that's interesting.... but I think it's no problem to integrate the script into yours. So I would suggest to remove the GPIO init and just make a call to to PID detection/removal routine.

                                        @semper-5 Looks like the script is not setting GPIO 25 high according to your GPIO readall

                                          @Semper-5 Use sudo command for this

                                          echo "$GPIOpin2" > /sys/class/gpio/export
                                          echo "out" > /sys/class/gpio/gpio$GPIOpin2/direction
                                          echo "1" > /sys/class/gpio/gpio$GPIOpin2/value
                                          

                                          With GPIOpin2=25 it will be a self runner ;)

                                          @Yahmez Ah so you tried out without using the pullups? That's interesting. So I should investigate this ;) As I said: No POLOLU switch, no testing area.

                                          So I say thank you to both of you! You should integrate a small 3,3V regulator. Then it's no problem to generate this. So intead of

                                          python os.system("sudo shutdown -h now")

                                          hook to a stripped down script with sudo command

                                          # Detect PID or EMULATOR NAMES
                                          emucall="$(sed '4!d; s/\([\\"]\|[[:alnum:]_]\+=[^ ]* \)//g; s/[][(){}^$*.|+? ]/\\&/g' /dev/shm/runcommand.info)"
                                          espid="$(pgrep -f "/opt/retropie/supplementary/.*/emulationstation([^.]|$)")"
                                          
                                          # Handle calls and send TERM signal
                                          if [[ -n "$emucall" ]]; then
                                              emupid="$(pgrep -f "$emucall" | tr '\n' ' ')"

                                              touch /tmp/es-shutdown && chown pi:pi /tmp/es-shutdown
                                              kill "$espid"

                                          poweroff

                                            @cyperghost it's not just the Pololu, but the way everything is wired in the case, the existing switches plus the added parts to convert it for safe shutdown. The Pololu on it's own is straight forward. Pin 25 has a diode between it's self and the switch to protect it from the 5v. It's internal pullup pulls it high. When you hit the switch it connects to ground and pulls gpio 25 down, which the script detects and initiates the shutdown.
