@flashmaster hey flashmaster i solved it you need to go on https://github.com/mholgatem/GPIOnext follow his instruction install it and when you install it go to bash gpionext then configure and then choose keyboard just select random buttons and go back in with you retropie and go to configure and voila it will be recognised if you need further informations just reply

@tonaytan so guys I made a guide maybe someone wants to look into that because GPIOnext needs some commands that need to be added https://retropie.org.uk/forum/topic/12176/pigrrl-button-installation-need-advise

Private messaging isn't an available feature on this forum.

Mr.Monkeyface

I have tried this over and over but once I get to sudo cp waveshare-dtoverlays/waveshare32b-overlay.dtb /boot/overlays/waveshare32b.dtbo it never works I have tried both commands and nothing works. Any ideas.

sorry for bumping this old topic, but i've just got the 3.2" waveshare screen for a gamegear project, but when i go to run the 2nd command after installing a fresh version of retropie:

sudo cp waveshare-dtoverlays/waveshare32b-overlay.dtb /boot/overlays/

I get the below message:

cp: cannot stat 'waveshare-dtoverlays/waveshare32b-overlay.dtb': No such file or directory

any ideas please?

cheers

You should look for updated instructions on how to install the screen - the repository mentioned in the instructions has been restructured and the filenames don't match. Look into the repository documentation at https://github.com/swkim01/waveshare-dtoverlays and install your screen.

sorry about that thank you for the update. all instructions followed and i've got the fb1 folder. when i add the extra lines in and then reboot... i'm still getting a white screen on the waveshare 3.2 but retropie is showing on my monitor
