RetroPie Scripts

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%

Usage

1. Run from bash

cd scripts
bash toggle\ mute.sh

2. Symlink into RetroPie Menu

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

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

3. Create new System for scripts

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

4. Run script from GPIO

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
