@nowun said in <SOLVED!> Retropie with C4 labs galaxy LED case mod.:

@clyde Thank you! That worked perfectly. I added "sudo python /home/pi/caseled/galaxy.py &" in before emulationstation and it boots up like a charm pre loaded with the settings I edited the script for the LED's.

If the script doesn't need administrative rights, you can omit the sudo before the command. It adds a tiny yet easily done bit of security to your system.
