      Thanks for all the work you have put into this, I was excited when I was pointed to this thread, sadly this did not work for me though. I am using the Pololu mosfet board in a Retroflag/NESPi case. I followed your steps but it was very odd because when I powered down via the switch the power LED on the case remained lit (faintly) after the pi shut down. It also did not save the meta data when shutting down from ES or from an emulator. Does the script HAVE to be located in /etc/ ?

        @yahmez no. You can put it wherever you want (and adapt your killes.service file accordingly). Make sure to make the script executable (I forgot to mention this in the OP. Will update it soon.).

        chmod a+x /path/to/killes.sh

          @yahmez Can you please provide your shutdown script? Maybe this gives the kick ;)
          @meleu I'm hunting down that rabbit - it's name is BASH

            I thought this would work for any shutdown script? 😜

              Thank you, this got the script working. Only problem is the case LED remains faintly lit. I cannot figure this out... I mean everything shuts down, the fan turns off, but the LED is still getting a little bit of power. Somehow by using the killes script the mosfet switch stays on. The only thing that can keep it on after the power button is is turned off is a pi GPIO staying high. But then again it's not fully on because the pi and fan are off... it's puzzling. I added a GPIO.cleanup() line to the end of my script but it did not seem to matter.

                After 5 minutes the LED fully extinguishes, so I guess this is a non issue even though it perplexes me. Thank you @meleu for working coming up with this graceful exit to ES. I really appreciate it.

                  Yes. This is the intention of my approach here. ;)

                  I'm glad to know it's now working for you!

                  Have a nice weekend.

                    @yahmez Yes the solution from @meleu is working in general (thanks to him!)

                    ... but I just want to take a look how the mass of these scripts are written. I'm currently working on annother way to shutdown and to give the user more control about the Pie.

                    One disadvantage will be that the shutdown scripts (bash, python or any other language) needs to be modified a bit. On the other hand, there will be no need to add something manually to systemd.

                    I don't know which method is better and I don't want to judge about. In the end the user decides on his own. The way how this script was born can be read on the first posting. And we can thank @meleu for his long breath and brillance in improve such scripts.

                    For me: It is always better to have two working ways ;)
                    Thanks for your help...

                      @BuZz do you think it would be valuable to add the trick described in the OP as an option in emulationstation.sh script module?

                      Summing up what it is: a way to ensure that ES will cleanly exit saving all metadata right before any shutdown/reboot.

                      If yes I can submit a PR for your evaluation.

                      EDIT: I'm thinking about an option like "Cleanly exit ES at any shutdown/reboot."

                        @meleu It's an issue with 3rd party reboot scripts? Looking briefly at op, I don't see why this is needed in RetroPie (it's not a RetroPie problem).

                          Not only 3rd party reboot scripts, but any shutdown method different than ES quit menu (example: "Perform reboot" on retropie_setup while ES is running, or shutdown -h now or reboot via SSH).

                          Looking briefly at op, I don't see why this is needed in RetroPie

                          Before the "Favorites/Last Played" feature was implemented, the "save metadata on exit" wasn't so important. But now it is. It can be really frustrating to lose your favorites after spending some time curating the list...

                          RetroPie doesn't actually need this, but it would avoid several topics here in the forum with people asking for help on how to not lose Favorites/Last played data when shutting down the pi with power buttons like Mausberry, Powerblock, etc.

                          (it's not a RetroPie problem)

                          Well, I have no intention to label it as a "RetroPie problem", but here is a 100% clean RetroPie use case (no custom configs/hacks involved):

                          1. Boot you raspi.
                          2. In ES add some games to Favorites.
                          3. Launch and exit some games (just to add some entries in the Last Played).
                          4. Launch retropie_setup via RetroPie Menu in ES.
                          5. Perform a reboot via retropie_setup.
                          6. After rebooting check that your Favorites/Last Played wasn't saved.

                          IMHO adding that trick as an option in emulationstation.sh script module has more pros than cons.

                            @meleu Well my advice would be to not reboot from retropie-setup and use ES. Maybe I should add a warning about rebooting when launched from ES. 3rd party reboot scripts can easily kill and wait for ES first. I'm not keen to invade the init system with ES to handle reboot scenarios outside of ES.

                                @buzz Well you can add a file "es-sysrestart" to folder tmp and send SIGTERM to EmulationStation-binary PID only - then this script provided with ES will takeover the shutdown sequence. If no active ES-PID is available the usual system shutdown can be performed.

                                Of course a warning hint within RetroPie-setup is also considerable and needs no maintainment - just a bit of user brain :)

                                    Being a owner of a NESPi Case (and Pi 3 model B), can i follow OP's guide as it is right now? or is there something else i should do/know about to make it work?
                                    I've been trying to follow the whole thing but as a lesser-experienced linux user i still feel sorry to ask :s

                                        @meleu After trying the guide with my NesPi case, i get the same initial result that @yahmez got. It's not saving changes and i also get the LED remains faintly lit (though i don't mind if it's fully off after 5 minutes).

                                        @yahmez Have you performed extra modifications or anything to make it work? You posted this link ( https://pastebin.com/25GKw9xv ) but i am unsure of what to make of it.

                                            The script is killes.sh, and, yes, it must be executable. There's nothing wrong with the .service file. ;-)
