Please help, how do I fix an upside down screen that is also flickering?

I just downloaded gba for the first time on my window 7 laptop. I downloaded 7zip and winrar shortly after. Not sure if doing it in that order had something to do with the upside screen and flickering that keeps happening. How can I fix this? I attached an image below of what I keep seeing.

Switch the display driver to OpenGL 1.x

Sorry, but I don't really know how to go about doing that
