Also when tutorial said to download an image to install the screen: should I install win32disk on the raspberry to be able to write the screen image? Please help.

Understanding that many people have problems configuring their Kuman TFT display on the Raspberry Pi together with RetroPie, I have decided to make this step-by-step of how to install the Kuman TFT 3.5" display which you can connect directly to the GPIO ports of the Raspberry Pi and run your applications. A lot of people have been buying this Kuman display from Amazon and other online markets for its economical price but it is not an easy display to install for certain applications, compared to other displays that come with integrated HDMI ports that will surely be a lot easier to manipulate and start working.

I advise you to buy a GPIO cable or a ribbon cable to connect the display to the Raspberry Pi, because sometimes (and it happened to me) at the time of manipulating the display and fitting it on the pins of the Raspberry, the screen being so the thin can be broken easily.

Verify that you have RetroPie burn on your SD Card, if you have not already done so, click on the following link, install it and come back here to continue the steps.

Next, copy the following code to download the best driver from Github:git clone https://github.com/goodtft/LCD-show.gitchmod -R 755 LCD-showcd LCD-show/chmod +x LCD35­-show./LCD35­-show

If, after installing, the screen is a mess together with the TV missing icons or words, please connect via SSH to your Raspberry Pi and run this command:cd RetroPie­-Setup/sudo ./retropie­-setup.sh

The previous command will open the Retropie configuration file where in the end you have to look for something like SPEED and FPS and change the values to something like:dtparam=audio=ondtoverlay=tft35a,speed=62000000,fps=40,rotate=90#dtoverlay=ads7846,cs=1,penirq=17,penirq_pull=2,speed=25000000,fps=20,keep_vref$gpu_mem_256=128gpu_mem_512=256gpu_mem_1024=256overscan_scale=1
