Safe One Button Shutdown for Retropie/Retroarch/Raspberry Pi

[robertm]

Hi,
I am trying to make a safe one button shutdown for my arcade running Retropie, retroarch,Mame lr-2003 on a RPi4 with Canakit power supply, 32GB SD card, arcade controls, etc.

Multiple people have posted on this but I can find no clear answer.

I connected a momentary button to pins 5 and 6 (ground) on the RPi, added "dtoverlay=GPIO-shutdown" to the config.txt file, and rebooted the machine.

When pressed the system logs itself off (OK Standby but then I can flip a switch (unplug) the unit for complete shutoff)

Question 1) I have read that pressing this button causes "metadata to not be saved/lost." Is this correct? If a ROM (OR even just idle in Emulation Station...) is running when the button is pushed, does this cause data loss?? And if it does....

Question 2) What data is lost? The only thing I care about are the High Scores for the games, and not corrupting the SD Card, and....

Question3) Is there a software only script I can put somewhere that would shutdown down ES and then the RPi4 correctly for No data loss????

Thanks!
Rob

@robertm this is the one i have used and i have not come across any problems with it

I appreciate the reply but have nowhere near the technical background to understand let alone impliment those instructions. I am a complete tech noobie.

Is what I have done (momentary button to pins 5 and 6 (ground) on the RPi, added "dtoverlay=GPIO-shutdown" to the config.txt file) going to cause data loss when used?????

Thanks,

Rob

Seconded. Once you configure it, it works like a charm. I can even shutdown safely while a game is still running.
