      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
