      My knowledge of Python is pretty much nil. I haven't had any real coding background whatsoever. I've tinkered and modified some stuff ini files for the original xbox to help automate flashing bios and setting up hard drives the way I like it. But that's really it. I usually take other peoples code and modify it to suit my needs. I would like to go back to college someday to learn about coding. Thanks for the input.

        very lazy, didn't even try it :

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

        that can work, only for retroarch for now

        you should start this file from a custom.sh located at /recalbox/share/system (you need to create it). Create it yourself add python yourfile.py inside, chmod u+x custom.sh and reboot

            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 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
