hi
I installed ATXRaspi and the shutdown via the button is working fine.
But I can not get it to work by software in retropie.
I installed the NPN 2n3904, and run the script.
please need help....
thanks.
Sorry for my bad English, native spanish jejejej :P :P :P ::) ::) ::)
All the info I have on the subject is on the ATXRaspi page (https://lowpowerlab.com/guide/atxraspi/full-pi-poweroff-from-software/).
it should be similar, you create reboot/shutdown aliases that assert the NPN transistor base from your GPIO.
I have not tried this on retropie.
