RetroPie launcher

To run this application automatically on boot, you can use the retropie-launcher.sh script. This script is designed to be called from RetroPie's autostart.sh file.

Assuming retropie-launcher.sh is located in /home/pi/modbay, you can edit /opt/retropie/configs/all/autostart.sh on your device to automatically start modbay.

To run the application once and then exit to the command line (or Emulation Station if configured), change autostart.sh to:

/home/pi/modbay/retropie-launcher.sh

If you want the application to restart automatically if it exits (for a kiosk-style setup), you can wrap the command in a while loop:

while true; do
  /home/pi/modbay/retropie-launcher.sh
done
