@griff How does it plug 'directly' ? GPIO/HDMI ? Check the screen vendor instructions on how to get it to work with Raspbian and apply those instructions to your RetroPie system.

@mitu no i will thank you again for your help and your patience I have other requests to finish but I think I should go to another topic? 1- how to configure arcade buttons and joysticks? 2- when I enter the Master system console everything is blocked, I can not do anything and I am forced to turn off and on.

@hurricanefan Here's hoping!

@chip hey finally I solved this. I did not flash the file with Applepi Baker instead, I used Etcher. Thank you so much for your reply! :)
