      I have had this screen running on Raspbian by downloading a driver and unzipping it in the home folder on my Pi 3B+. How do I do this in Retropie? I have coppied the extracted files to a USB drive. I am not sure where abouts to place them on a fresh install of Retropie and have been unable to find anything about where to place LCD drivers. I can get to the terminal but from there I am unsure how to proced. Thanks in advance for any help offered.

        The RetroPie Pi image is based on Raspbian, if you have installed the RetroPie image, you'll have a Raspbian Lite installation underneath.

            @mrditchy So I enabled SPI then I copied the folder to the home folder and unzipped it, however I couldn't get it to work. My screen is still just lit. The hdmi works. I am still totaly stumped.

              Do you get any errors by running the drivers' installation or the drivers are installed, but the screen is not working ? Do you have a link to the installation instructions for the screen/drivers ?

                @mitu I couldn't get the screen to work at all.Just a white out.No errors to be seen. When I boot with an hdmi monitor in it works The driver is at http://kedei.net/raspberry/raspberry.html and it is the SPI_128M_60HZ. I found another seller on ali that has the same screen and some instructions to follow that downloaded the driver into retropie but I couldn't get it to run. I enabled SPI but no joy. https://www.aliexpress.com/i/32913141070.html is the ali link that runs a script from git hub.

                  So here I am six months later pleased to report that I finally have got this screen working. Kedei have changed the download page to https://kedei.net/download.html On a separate computer I downloaded the driver as a zip file, which I copied to a USB drive. I then copied the file to /home/pi (in RetroPie) I then unzipped it. This gave me a new directory called LCD_driver. I then did a chmod -R 777 LCD_driver. Despite the page on ali saying do not use FBCP driver I used it with the ./LCD35_fbcp command. The screen now works. I hope this post helps anyone who is having difficulty with this screen.
