Raspberry pi zero gpio controller

[kkokkinos]

I connected alla the buttons on the gpio headers of the zero however the pi doesnt recognise any button. I saw some videos about how to enable them from the recalbox.conf file but i cant find it anywere. I am using winscp and I have root access

@kkokkinos There are a few GPIO based controller drivers available in RetroPie:

• https://retropie.org.uk/docs/GPIO-Modules/
• https://github.com/recalbox/mk_arcade_joystick_rpi

I think you're trying to use the mk_arcade_joystick_rpi one ? If so, then you need to install it first from the RetroPie-Setup script (it's in the drivers section of the packages) and then configure it - as described on the Github page of the driver. You can ignore all the installation steps and just look at the pinout and make sure you connected the wires correctly, then jump to the Loading the driver section.

There is no recalbox.conf file in RetroPie, that is part of the Recalbox image -a different project.
