Power Button in 2022

[lindsay]

Retropie 4.8
Raspberry Pi 4 2GB
Official power adaptor
PS3 controller
lr-Mame 2003 (0.78) and 2010

Hi All,
What is the current recommendation for power buttons and script to run them?
I tried following old ETA Prime tutorials but they didn't work with Retropie 4.8

Also on this forum the latest I could find was from 2 years ago.
Thanks so much

Redirecting the output of rc.local to a log file yielded this error:

• sudo python /home/pi/scripts/shutdown.py
  Traceback (most recent call last):
  File "/home/pi/scripts/shutdown.py", line 3, in <module>
  import RPi.GPIO as GPIO
  RuntimeError: This module can only be run on a Raspberry Pi!

Well, it definitely is being run on a Raspberry pi!

Save yourself the trouble and use @cyperghost's shutdown script - it's at https://github.com/crcerror/ES-generic-shutdown.

@mitu thanks, this is from 2018, does it still work in 2022?
And it seems it needs special case with a special power switch installed, or am I mistaken?

Yes.

No, it supports a number of special power switches, but it works also with a generic GPIO button.

@mitu Many thanks.
