      The script is not that hard to adapt :

      • list binaries that one wants to shutdown. So far, there is moonlight, retroarch, fba2x, kodilauncher.sh, mupen64plus, scummvm
      • instead of getting cmdline, get exe (it's a symbolic link)
      • check that exe is among the listed binaries. If so, kill the pid

      One could make that script way more dirty : just throw a kill of all known processes, anyway only one of them is supposed to run at once

      The next recalbox version will add those binaries : dosbox, PPSSPPSDL, reicast.elf, linapple, x64

      What's your knowledge of python ?

        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
