@mitu Ah, that scuppers those plans then. I think I'll give this up as a failed experiment. I did manage to get Kodi to launch from my green button by importing psutil and check_output and changing the code to espid = int(check_output(["pidof","-s","emulationstation"])) es = psutil.Process(espid) es.suspend() Kodi = subprocess.Popen("/home/pi/RetroPie/roms/ports/Kodi.sh") Kodi.wait es.resume() But then the script would no longer start from my crontab on boot so not really usable.

Mystic Mine is a Python game included in RetroPie. You can find it in the Experimental packages. I strongly recommend you to study how this game is programmed as it runs very well on the Raspberry Pi. The scriptmodule that installs and configures this game in RetroPie is here: https://github.com/RetroPie/RetroPie-Setup/blob/master/scriptmodules/ports/mysticmine.sh

I just added an exec functionality to my multiplexer: The idea is, to allow external programs to be executed on a button press. This can be used to enable/disable special functions which are triggered by external executables: Here is a demo and you get an idea why I need this functionality:

@sdabbs I don't know sorry. Try using pip to check and upgrade py modules. pip list pip upgrade xxx.xxx

I fixed it after writing it all out above I figured it out. First off I needed to run the below and reboot as it turns out not all functions where doing there job: sudo apt-get install build-essential python-dev python-smbus python-pip python-imaging python-numpy git Then when you restart the error goes away. Also the site has the GPIO pins incorrect as it should of been as follows. Now all works with options and game name displaying will check album art later.

I want to start emulationstation on-demand, this is what I've come up with: Emulationstation heavily depends on a terminal being allocated for it to work. It switches a lot between graphical and text-mode. So in "/etc/systemd/system/my-emulationstation.service": [Unit] Description=my emulationstation [Service] User=pi ExecStart=/usr/local/bin/run-emulationstation Type=simple StandardInput=tty-force TTYVHangup=yes TTYPath=/dev/tty20 TTYReset=yes Also, there's a bug that requires emulationstation to be started inside /home/pi, so in "/usr/local/bin/run-emulationstation": #! /bin/bash # switch to same tty allocated in .service chvt 20 # cd to home cd /home/pi # run emulationstation in foreground process /opt/retropie/supplementary/emulationstation/emulationstation.sh And for the curious: I want it to start when specific hardware is attached, specifically an 8Bitdo Zero Bluetooth Gamepad. So in "/etc/udev/rules.d/50-my-emulationstation.rules": ACTION=="add", SUBSYSTEM=="input", ATTR{name}=="8Bitdo Zero GamePad", TAG+="systemd", ENV{SYSTEMD_WANTS}="my-emulationstation"

@John_RM_70 Try one command at a time and see which ones locks up the Pi. It's probably tvservice, but it could be because of the previous command, which specifies might specify an invalid mode. Have you tried tvservice -p (preferred mode) ?

@mitu said in Modify Power Button Behaviour to 'Hold for three seconds'??: You can increase the bouncetime from 2sec to something larger. Even as it is now, just a single quick push will shut the software down - i dont have to hold the button at all. Perhaps I need to use a different script that relies on the button being held.

@JToivonen got what you mean and here is the "un modified" solution...simply if you're playing plug the usb controller and when you finish just unplug it and it will shutdown automatically!, even when a power trigger happens "electricity went off then come back again" and found that your gamepad isn't connected it will shut down :) here is the python file you just need to edit the line that kills qjoypad to kill whole system add poweroff or shutdown -h as you use in your momentry switch don't forget to make the file run at start and special thanks to pablo idea behind the script is that system creates a js0 file for controller 1 inputs and js1 for controller 2 when connected and so on, the script searches for that file if it's found that mean you've connected the gamepad and probably playing a game and when you finish unplugging the gamepad removes js0 file and when the script discovers the file is not found it kills an app process called qjoypad which you'll change to shutdown please note you're not gonna use //User Variables section in this code so just ignore it.

Ok I see... So it's possible to use my script and retropie However, only on a computer. Thanks for the information I wasn't aware that on RP almost all emulators don't run on X. Thanks a lot :)

@mesym Well I don't know what's wrong but this worked for me. It starts Tetris and shows me pointer adress. Something wrong with your py-fu? import os import time import subprocess p = subprocess.Popen(['/opt/retropie/supplementary/runcommand/runcommand.sh','0', '_SYS_', 'gb', '/home/pi/RetroPie/roms/gb/Tetris (JUE) (V1.0) [!].gb']) while 1: print(p) time.sleep(5)

@mitu I did it, but then suddenly my wi-fi dongle stopped working. Then I tried some more troubleshooting attempts for that and messed stuff up even more. Much as it pains me, I'm just reinstalling RetroPie and doing it all from scratch. I made backups of everything, so hopefully I'll be able to salvage some of my customizations.

i'm afraid I cant find much on how to output to this from python. Im no coder, it needs to be call-able from python once Ive done with my process. thanks for info!.. do you have any more? Other options please! what other options do I have to get my character input into ES and retroarch please?

I'm having the error 404 today, but other things in github still ok. edit: Typing wrong was what got me into that, now it's alright

so my remote monitering script helped rule out overheating on my pie its become unstable suddenly... so time to backup and reflash

Hi you can try it your self from command line type wget https://pyskool.ca/downloads/pyskool/pyskool_1.2.1-1_all.deb sudo dpkg -i pyskool_1.2.1-1_all.deb run it with pyskool if it needs python install it with apt-get install python

Thanks! I'll give that guide a go, and see what turns up.

@mitu I gave it another shot and moving the line to autostart did the trick! Music still starts and I get to keep the music folder on my usb stick. Thanks!
