Need script help for Retroflag NESPi soft power switch hack

[Dan Zettinger]

I modified the retroflag NESPi case with the guide by James White to add a software shutdown switch however the script in the guide is for retropie and I have no experience converting this script to work with recalbox.

Here is the guide for reference: https://drive.google.com/file/d/0B9AzTQWe_cTFem1JS01HVU1GMDg/view

The main item I need to work is the power button with the reset button being less important. Has anyone been able to get this working and if so would you share the script you used?

Alternatively, would I be able to modify the existing 'rpi-pin56-power' script to change the pins?

Thanks in advance

@dan-zettinger there is already a script posted on this forum, have a look in the search bar ! Only for 4.1 !

Edit : idon't find anymore the post
It was a script with short press = emulator quit, long press = shutdown
By @supernature2k i think ?

Edit2 : i found it !!

I try to solve it so You have one GPIO set to high, that delivers 3,3V ... as long as this GPIO is setted high the mosfat delivers power. When does the GPIO not deliver power? Right... if the Pie is shut off!
The cap will loose power and the mosfat output also closes.
POWER cutoff
press the power switch again
the Cap colect power again = Switch should be as closed
then Power to the Pi....

@dan-zettinger Hello, have you managed to make the code changes to work as in the retropie?

I know they released a new Nespi case + early April 2018 and has a working safe shutdown and safe reset buttons. They include instructions on how to setup the script. Wondering if anyone can port that over to recalbox, would be awesome.
