I’m having trouble making all elements of the RetroPie experience fit on my screen.
If I set overscan_scale=1, all emulators fill my screen vertically as expected, but the Emulation Station UI flows over the edges of my screen.
If I remove overscan_scale=1, then Emulation Station fits fine, but none of the emulators fill the screen vertically – there is empty space on the top and bottom.
The only setting I’ve found that corrects this is using hdmi_group=1 and hdmi_mode=1 to force VGA mode. This lets both Emulation Station and emulators to scale properly. Unfortunately, Emulation Station looks awful at this low resolution.
