After changing a RetroArch 1.9.0 CEX core "Aspect Ratio" setting from the default "4:3" to "Custom" and running games with a different core, I have to change the latter's "Aspect Ratio" setting from "4:3" to "Custom" because I have a white screen when running games with them since the "Aspect Ratio" setting is blank for some reason insted of being set to "Custom".
