@josdelsan said in SPI connection driver alternatives for ILI9341V display?:

Before I go back to RPI forum, I would like to know where I can read more about how emulationstation GUI is loaded so I can provide some context, otherwise I will be sent back here again.

You can replace EmulationStation with any SDL/non-SDL app that uses a GLES/OpenGL context and you have the same result (i.e. RetroArch or Mame). There's nothing special about EmulationStation and you can achieve the same result with any of GL test applications from the libsdl2-tests, like testgl2 or testgles2 (from /usr/libexec/installed-tests/SDL2/).
