All of my overlays are 16:9 and stretch in 32:9, ruining them. I was hopeful when I upgraded to a super ultra widescreen monitor this would not be an issue. Is there a way to force Retroarch to start full screen in a 16:9 resolution for the interface and then when I start a game continue to remain in 16:9 while utilizing custom frame sizing to fit with bezels? I do not want retroarch to stretch nor do I want to play windowed.
p.s. an even cooler solution would be to have 2x or 3x games running simultaneously in separate bezels within the same retroarch window(full screen borderless) but I doubt that is possible.
