@cloc140 said in Enabling wifi in Retropie at installation on Picade Pi 4b:

it’s written on screen to press button A but I tried to press all buttons without sucess.

I assume you're taking about the controller configuration screen ? AFAIK the Picade needs a driver to be installed in order configure the input.

If you're trying to enable WiFi so that you can download and install the driver, then the easiest way would be to create a wpa_supplicant.conf configuration file on the sdcard - see https://retropie.org.uk/docs/Wifi/#connecting-to-wifi-without-a-keyboard. You can similarly enable SSH to be able to connect to the Pi and run commands - see the getting started documentation from the previous link I posted.
