Useful bash scripts for use on RetroPie systems

Download the scripts:

cd ~
git clone https://github.com/bverc/retropie-scripts scripts

• restart emulationstation.sh Restart Emulation Station
• safe shutdown.sh Perform safe shutdown of the system
• toggle bluetooth.sh Turn Bluetooth on or off
• toggle wifi.sh Turn wifi on or off
• toggle mute.sh Mute or Unmute speakers
• volume up.sh Increase volume by 10%
• volume down.sh Decrease volume by 10%

cd scripts
bash toggle\ mute.sh

Symlink scripts into retropiemenu folder so they are accessable from the Emulation Station menus

ln -s ~/scripts/toggle\ mute.sh ~/RetroPie/retropiemenu/

Create a new system in Emulation Station so all scripts appear in their own group.

Copy default es_systems.cfg and edit to ensure it is not replaced during upgrade

sudo cp /etc/emulationstation/es_systems.cfg /opt/retropie/configs/all/emulationstation/es_systems.cfg
sudo vi /opt/retropie/configs/all/emulationstation/es_systems.cfg

Add the following system entry:

  <system>
    <name>scripts</name>
    <fullname>Scripts</fullname>
    <path>/home/pi/scripts</path>
    <extension>.sh</extension>
    <command>bash %ROM%</command>
    <platform/>
    <theme>scripts</theme>
  </system>

restart emulationstation or reboot

If you wish, you can create a theme for the new system

Run a python script to run a bash script on GPIO button press. Some examples are provided:

• gpio-script.py maps scripts to GPIOs and runs script each time paired GPIO is pressed
• gpio-shutdown.py detects button press, waits 2 seconds and checks again before shutting down system

To run at boot, add to crontab.

crontab -e

At the bottom of the file, add the line:

@reboot python /home/pi/scripts/gpio-script.py

reboot
