      I think import time is needed for the sleep function.
      Also, I would do it the other way for button press: GPIO.PUD_UP and GPIO.FALLING

      the code:

      import os
      import RPi.GPIO as GPIO
      import time
      
      GPIO.setmode(GPIO.BCM)
      GPIO.setup(17, GPIO.IN, pull_up_down=GPIO.PUD_UP)
      
      def exitEmulator(channel):
          print('exitEmulator')
          os.system('killall retroarch')
          
      GPIO.add_event_detect(17, GPIO.FALLING, callback=exitEmulator, bouncetime=500)
      
      while True:
          sleep(10)

        Ok Guys, I made some test.

        I put a cable on Pin5 and pin6 and run the following code:

        import os
        import RPi.GPIO as GPIO
        import time
        
        GPIO.setmode(GPIO.BCM)
        GPIO.setup(3, GPIO.IN, pull_up_down=GPIO.PUD_UP)
        
        def exitEmulator(channel):
            print("exitEmulator")
            os.system("killall retroarch")
            
        GPIO.add_event_detect(3, GPIO.FALLING, callback=exitEmulator, bouncetime=500)
        
        while True:
            time.sleep(10)
        

        And... it's working 🙂

        Of course in this current state, it's only working with retroarch emulators

          haha i'm the man 😄

          Seriously, most of emulators are listed in the recalboxFiles.py. Would need to improve it because all bins are not listed there. But I really like this idea : kill the running emulator, or even reset the game (there is a topic on it somewhere, will gid this and update my post) -> https://forum.recalbox.com/topic/3435/game-reset/6

            solution via python with network commands:

            import os
            import RPi.GPIO as GPIO
            import time
            import socket
            import sys
            # addressing information of target
            IPADDR = "127.0.0.1"
            PORTNUM = 55355
             
            # enter the data content of the UDP packet
            PACKETDATA = "RESET"
             
            # initialize a socket, think of it as a cable
            # SOCK_DGRAM specifies that this is UDP
            try:
                s = socket.socket(socket.AF_INET, socket.SOCK_DGRAM)
            except socket.error:
                print 'Failed to create socket'
                sys.exit()
            #s.connect((IPADDR, PORTNUM))
             
            # connect the socket, think of it as connecting the cable to the address location
            
            data = bytes(PACKETDATA)
            
            GPIO.setmode(GPIO.BCM)
            GPIO.setup(3, GPIO.IN, pull_up_down=GPIO.PUD_UP)
            
            def exitEmulator(channel):
            	print("exitEmulator")
            	print(IPADDR)
            	print(PORTNUM)
            	print(PACKETDATA)
            	s.sendto(PACKETDATA, (IPADDR, PORTNUM))
                
            GPIO.add_event_detect(3, GPIO.FALLING, callback=exitEmulator, bouncetime=500)
            
            while True:
                time.sleep(10)

              @supernature2k Hi,

              I'm replying to this old topic because I'm currently working on a project that needs such a feature. I tried your last script, I just removed GPIO code at for now to test, so here is my code:

              import os
              import time
              import socket
              import sys
              # addressing information of target
              IPADDR = "127.0.0.1"
              PORTNUM = 55355
              
              # enter the data content of the UDP packet
              PACKETDATA = "RESET"
              
              # initialize a socket, think of it as a cable
              # SOCK_DGRAM specifies that this is UDP
              try:
                  s = socket.socket(socket.AF_INET, socket.SOCK_DGRAM)
              except socket.error:
                  print 'Failed to create socket'
                  sys.exit()
              #s.connect((IPADDR, PORTNUM))
              
              # connect the socket, think of it as connecting the cable to the address location
              
              data = bytes(PACKETDATA)
              
              print("exitEmulator")
              print(IPADDR)
              print(PORTNUM)
              print(PACKETDATA)
              s.sendto(PACKETDATA, (IPADDR, PORTNUM))
              

              So to try it, I start a retroarch game then I launch the script:

              # python rpi-exit-emulator.py 
              exitEmulator
              127.0.0.1
              55355
              RESET
              

              But in fact it does nothing, I'm still in the game (with no reset). Any idea ? 🙂

                @oyyodams it's RESET, not exit 😉

                  @substring yes that's it's supposed to do... but no reset by the way...

                    @oyyodams check on command line if you can connect to the port 😉 some netcat commands should do it

                      @substring Well I found a great doc on the wiki. But...

                      • I can't use netcast: nc is not include in this buildroot build (and I can't rebuild by now)
                      • It seems retroarch doesn't respond to any command. I tried to edit retroarch.cfg to add network_cmd_enable = "true", nothing better (even after reboot)

                      I will not let go;)

                            Ok solution:

                            network_cmd_enable = "true" has to be added in /recalbox/share/system/configs/retroarch/retroarchcustom.cfg
