Currently I bought one of these touchscreen that connect to the gpio and need some help to install the driver on retropie and raspberry pi 3 b (after succeed on pi 3 I will try the Pi Zero too).
Since I am a heavy windows user and command line isn't my strongest skill I am here to ask for all gurus for some help or advice.
So, I tried to follow the instructions of the seller (see link):https://www.waveshare.com/wiki/3.5inch_RPi_LCD_(A)
I know that the screen is working because I made one image with raspbian with driver already installed by someone else, but I can't make work on Retropie.
Following the instructions, I stopped at the point that I have to install the drivers. The problem is that I already try both drivers that is said in the link/instructions (170703.tar.gz / 161112.tar.gz) but for sure is missing some command line that I can't figure out by myself.
The screen maker is VKmaker and they use the drivers of waveshare screen.

Any help would be really appreciated!
I will be happy with the screen display some image, the touchscreen isn't necessary.
