my wiring is as follows:
momentary switch pins 5-6
led positive pin 8 with resistor
led negative pin 6 (bridged with switch's pin)

Hi again,
So, after all I added a momentary switch according to https://github.com/recalbox/recalbox-os/wiki/Add-a-start-stop-button-to-your-recalbox-(EN).

I uncommented only:
system.power.switch=PIN56PUSH

The result was being able only to turn on the Pi with the switch. Turning it off doesn't work.
Also the LED was on for about 3 seconds after I turned the pi on, afterwards it was going off. I managed to keep the LED on with a solution I found in another thread (https://forum.recalbox.com/topic/11266/led-status-light/10)
by adding the line "enable_uart=1" in the config.txt

Any idea why my switch isn't working for pi shutdown?
(rpi3, recalbox 17.12.02)

Not sure if this is what you mean... but I am using this great little GameList editor: https://forum.recalbox.com/topic/9265/soft-gamelist-editor

You can activate the "god-mode" and then you'll be able to select and remove roms, as well as the entries from the gamelist.xml.
You just have to give the path of the roms folder.

Perfect! Thanks!

Can I use a power ON/OFF switch togeter with an LED without wiring a RESET momentary switch?
I only want power switch and LED according to that guide:

Hi there people,
I know we can change the emulationstation music, also change the music for a specific system, but is it possible to change a system's music AFTER selecting a system while navigating its games?
