    Hello;

    I’d some problem with my save when I shutdown the raspberry; see: http://blog.petrockblock.com/forums/topic/saved-game-lost-after-reboot/
    All is now OK with a restart every time that I’ve finished to play.

    I buy a shutdown circuit to shutdown the raspberry pi with a power buton.
    With this module, when I push the power buton, the command “sudo poweroff” is send to the system.
    I can modify this script with some other command.

    Is it possible to send a system command to shut down the emulator before shutdown the Raspberry ?
    With that, there will be no more problem with my save.
    How can I do that ?

    I run a “sudo ps” but don’t find an explicit process name about retropie or retroarch.

    /etc$ sudo ps

    I’m a very newbie in linux command.
    But I’ve found that:
    /etc$ ps aux | grep *retro*

    pi 2662 0.0 0.1 1752 508 tty1 S+ 17:53 0:00 sh -c /home/pi/RetroPie/supplementary/runcommand/runcommand.sh 1 “/home/pi/RetroPie/emulators/RetroArch/installdir/bin/retroarch -L /home/pi/RetroPie/emulatorcores/picodrive/picodrive_libretro.so –config /home/pi/RetroPie/configs/all/retroarch.cfg –appendconfig /home/pi/RetroPie/configs/megadrive/retroarch.cfg /home/pi/RetroPie/roms/megadrive/Streets\ of\ Rage.bin”
    pi 2663 0.0 0.3 4276 1300 tty1 S+ 17:53 0:00 /bin/bash /home/pi/RetroPie/supplementary/runcommand/runcommand.sh 1 /home/pi/RetroPie/emulators/RetroArch/installdir/bin/retroarch -L /home/pi/RetroPie/emulatorcores/picodrive/picodrive_libretro.so –config /home/pi/RetroPie/configs/all/retroarch.cfg –appendconfig /home/pi/RetroPie/configs/megadrive/retroarch.cfg /home/pi/RetroPie/roms/megadrive/Streets\ of\ Rage.bin
    pi 2690 49.7 1.7 76448 6888 tty1 Rl+ 17:54 59:12 /home/pi/RetroPie/emulators/RetroArch/installdir/bin/retroarch -L /home/pi/RetroPie/emulatorcores/picodrive/picodrive_libretro.so –config /home/pi/RetroPie/configs/all/retroarch.cfg –appendconfig /home/pi/RetroPie/configs/megadrive/retroarch.cfg /home/pi/RetroPie/roms/megadrive/Streets of Rage.bin
    pi 16527 1.0 0.2 3540 808 ? S 19:53 0:00 grep retroarch.cfg

    /etc$ ps -u pi

    PID TTY TIME CMD
    2530 tty1 00:00:00 bash
    2539 tty1 00:00:00 emulationstatio
    2543 tty1 00:00:16 emulationstatio
    2662 tty1 00:00:00 sh
    2663 tty1 00:00:00 runcommand.sh
    2690 tty1 00:59:35 retroarch
    11569 ? 00:00:00 sshd
    11570 ? 00:00:00 sftp-server
    12057 ? 00:00:00 sshd
    12058 ? 00:00:00 bash
    16614 ? 00:00:00 ps

    With the Time start and Time elapsed columns I thinks the process is the PID 2690
    But witch one should I kill: The one from “ps -u pi” or the one from “pa aux | grep *retro*”

    How can I kill a process without know the number ?

    i dont understand why you need to do this all you do is save your game then load up the ingame gui and click quit retroarch and it takes you back to the emulators screen where you can hit the start button on your pad or whatever you have set the menu to then click shutdown and thats it.

    if you have an issue with saving make sure the save directory is set to default on the ingame gui and if it is and its still not working run
    sudo chmod 777 /home/pi/RetroPie/roms
    and then reboot and try to save and see if that fixes it

    Hello;

    I’m want to do that to never forgot to exit with my gamepad to save.
    And I’ve set my raspberry into a NES case. That way I can use the power and reset buton of the case.
    If I shutdown the raspberry with my gamepad, the buton power will always stay in “power on” mode and the red LED always active even if the raspberry is shutdown.
    *****************

    Problem solved, a Simple command “sudo poweroff” works.
    Even if I have not exit the game.
