    @mediamogul quick side note here if I may: what were the broad steps you followed to build your OSMC dual boot? I have Kodi setup, but I really do prefer the OSMC flavor. Always have.

      NOOBS was used for the setup I'm currently using. Since both sides will need to be redone for Stretch, I plan to use PINN to replace it in the months to come, as it offers RetroPie as one of it's default install options. As you may be aware, using NOOBS for this involves converting a RetroPie SD image to be used. After that, it's just a matter of booting it up and selecting RetroPie to install alongside the already available OSMC option.

      When it's all said and done, you either have the option of using a dual boot selection screen every time the Pi starts, or you can take a page out of the Multi Boot Pi book like I do and use a custom addon for Kodi that launches RetroPie, along with a custom script in RetroPie to return to OSMC. All that said, besides mentioning PINN as an option, I'm probably burying the lead in that you could just get an install image from the Multiboot Pi page with OSMC and RetroPie already configured for this. While it will install older versions of both, they can of course be updated independently as they would normally.

        @meleu I am still not able to get the metadata to save from my process. Is there something I could look at to help troubleshoot the issue.

        I have verified that the killes.service is enabled and therefore running.

        I can execute the killes.sh script from the command line and emulation station processes do terminate. After I power down and backup, the metadata has been saved.

        My issue is when I execute the 'shutdown' command from within emulation station as a menu item. The command performed is the 'shutdown now' command, but the meta data is never saved when I execute it this way.

        Any thoughts that would help me debug would be great.

          Any updates on the MD not saving?

          I've made no progress. MD only saves when performing shutdowns or restarts within ES menu....not button :/

            I just wanted to update my previous post as I did not include the proper information before. I am running Retropie v4.3, RPi3 Model B, 5v @2.5A PSU, 32GB SandDisk Microsd.

            I have installed the killes service and installed the killes.sh script. I can successfully save metadata by running the script from the command line. I cannot save metadata if I run a script that does the 'shutdown now' command which is executed from the main retropie menu as was posted here: https://retropie.org.uk/forum/topic/10736/power-on-off-option-in-main-menu/3

            Additionally how do you put your system information into a footer in your post

              Hi! I´m on your previous situation: Modded Nespi Case soft shutdown, following PDF (working GREAT) and after some iso backups, I installed the killes.sh, but is not working... adding some favs and pressing power down button, and after power it up, favs didn´t save.

              I can see killes.service enabled from :~ $ systemctl status killes
              ● killes.service - Kill EmulationStation
              Loaded: loaded (/etc/systemd/system/killes.service; enabled)
              Active: active (exited) since Sat 2018-03-24 10:05:18 UTC; 3min 46s ago

              Is the fresh install your only way to go? For me, it would be a nightmare re-install 30gb of roms and ports, gamepad config, overclock... I´m making backups every now and then just to not repeat what it´s done (like 6 months of work here)

              So... how can I emulate the "fresh install" on my scripts? is something I should wipe from systemctl or something?

              Thank you!

                Sorry man, I really don't know what is causing this issue for people. Especially because the killes script worked for me both on a system I had already set up completely, and with a fresh install. Wish I could be more of a help here...

                  @meleu HI! I'm trying to make the gracefully finish to work but I can't and I don't know why... I follow all the steps even create the script in the same path than you (/etc) but it does not work. I'm using a raspberry pi 3 with the last version of retropie and shutdown script with a button connected to GPIO 3. Could you guide me about this?
                  Thanks

                    When using this with the Kintaro 9000 case, the power switch doesn't respond but the reset switch does. Using the reset switch won't save metadata. If anyone has experience with this, I'd love some help.

                    Pi Model or other hardware: Pi 3b
                    Power Supply used: 5.1v 2.5a
                    RetroPie Version Used: 4.3.17
                    Built From: Pre made SD Image on RetroPie website, updated to 4.3.17
                    USB Devices connected: dongle for wireless keyboard
                    Controller used: Official PS3 Controller
                    How to replicate the problem: Followed install instructions from Kintaro 9000, then followed instructions in this post

                      Hello fellows,

                      I've just updated the OP with the following warning:

                      UPDATE: many guys are reporting that this trick isn't working anymore. Maybe something has changed after an OS update, but I'm not sure. I don't use GPIO buttons to shutdown my RetroPie myself.

                      I'm currently very busy on other projects and unable to provide support here. Sorry mates..

                              @finaluser Yes yes... the killall method ;) It's the simpelest method and it will fail if there are emulators running in background.

                              The service @meleu gots following reason. You don't need annother script that explicitly shutdowns emulationstation. Sadly the service seems to not run correctly anymore (users reports that)

                              So I recreated annother script Multi Switch Shutdown Script that suppots all NESPicases, the Pimoroni ONOFFSHIM, the Mausberry and any generic button.

                              It will correctly shutdown emulators and ES and the reset button works more as an reset button ;) It shutdowns emulators if there are any running. Or it just restart ES if you are in main menu. The reboot option can be done by menu or via command line ;)

                                @meleu, I recently set up a safe-shutdown script for my Super Kuma 9000 case, and I ended up using a patchwork of your code, @cyperghost's, and @mediamogul's. It all seems to be running cleanly now, at least on my system - I tested shutdowns, resets, and full system reboots both from within Emulator Station and within a game, and it seems to be saving metadata correctly in all instances.

                                I hope this is useful to you or others who come across this thread!

                                I wrote it specifically to work with my modified kintaro pcb.py script, included at the end of this post. Though you should be able to call it from anywhere, as long as you pass it the appropriate option (default is REBOOT):

                                • --SHUTDOWN - Initiates a clean shutdown of any open emulators, then Emulation Station, and finally the Pi itself
                                • --REBOOT - Initiates a clean shutdown of any open emulators, then Emulation Station, and finally reboots the Pi
                                • --RESET - Initiates a clean shutdown of any open emulators, then a clean restart of Emulation Station. If Emulation Station is not open (ie, you crashed to the terminal somehow), this option will restart it.

                                Hopefully it's not too janky, I'm beyond rusty with bash and python.

                                # I stripped out the fan control functionality (it's not used in my build), and am working to make shutdowns / resets safe for Emulation Station.

                                # WIP Log:
                                # 180525 - Stripped out the fan control code with little issues.  Modified reset switch to indicate when it's changing functionality
                                # 		 - and to be generally less shitty
                                # 180526 - Replaced old code for shutdowns and resets (just calls to sudo shutdown) with appropriate calls to /opt/kintaro/killes.sh
                                # 		 - Also further tweaked reset button functionality.  Tapping reset will restart Emulation Station, holding it for 1-5seconds
                                # 		 - will reboot the system, and holding it for 5+seconds will cancel it.  System seems to be stable now, no metadata is getting
                                # 		 - lost on shutdowns or resets from within a game, or just emulation station itself.

                                  @tictac_93 This works in most cases ... yes

                                  But look. You take PID of runcommand and use pkill -P switch to kill child PID. That works in most cases but some emulators also just call annother process and this won't be catched by your method. You need at least annother pkill -P call.

                                  You should just use your python script and you can use the multi_switch and it's command line options. Therefore use a python call like output = int(subprocess.check_output(['./multi_switch.sh', '--es-pid'])) and you can check if ES is running. If the ouput is 0 then python interprets this as false if a PID is detected the value is grater than 0 - this interprets python as true.
                                  So the sniplet in python itself would be look like this.

                                  if output:
                                       os.system("./multi_switch.sh --es-poweroff")
                                   else:
                                       os.system("sudo shutdown -h now")
