      @cyperghost Hi, I tried your emulator detector too and the result was the same more or less. There were some emulators that dont stop... If you prefer I could write you throug the other thread.

        @julenvitoria Thanks! You are right the signal levels are ignored by some emulators.
        I would suggest to use kill -9 <PID>

        I will update both scripts. So you see - once again something new explored .... ;)

          Ok, so no errors to report. But the power switch doesn't work now.
          I temporarily took out the entry in autostart.sh just to see what would happen in putty. and like I said, no errors. but when i press the power button (off) it does nothing

              @semper-5 Please do so as you wrote. Take auto entry from autostart.sh!
              and do a manuel start via SSH to see error messages. I need the routine how the POLOLU acts with the switch.

              Please use sudo /path/to/switch.sh & command with the latest script version.

              @julenvitoria You are welcome! Thank you for testing. The other script is also working! I tested several times.

                @cyperghost it doesn't output any errors.

                I enter: sudo bash /home/pi/RetroPie/scripts/switch.sh &
                output: [1] 10921

                I think it s working to some extent because if I try to run it again it will tell line 18 & 20 write protection due to device being busy

                  @semper-5 That's okay ... this [10921] thing is the process number.
                  So what happens if you press the power button? With the script in background running?

                  You should see a message like:
                  Switch press 0 - Switchtype 1
                  ES-PID: 1232

                      @semper-5 What is the output of
                      cat /sys/class/gpio/gpio24/value

                      if the power button is pressed, and then if the power button is released?
                      It should be 1 if pressed and 0 if released

                      The script must be active for this ;)

                          @semper-5 That's the error here ... but tell me why? That's not possible! The python scripts are working?

                          Maybe @Yahmez knows the answer?
                          If we watch for input of GPIO24 (=power button), why there is no change in input value?

                            @cyperghost I know! Our frustration is real. I mean it works as it should with Yahmez's script. And just to be sure I am following your instructions immaculately, yours is the ONLY script I'm running on this fresh image.

                            Geez it was embarrassing you guys telling me to use Notepad++ and how to invoke the script LOL. but I do appreciate all your efforts to walk me through it. I'm just thinking you guys must be getting as frustrated with me as I'm getting frustrated with this not working - I'm yelling at this damn box like "you're making an idiot out of me in front of the community, damn you!" haha

                              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
