Hello!
Have issue with 240p option...

I've still use RPi4 with crt tv connected via composite cable, and it worked as default 720x480 - interlaced 60hz.

But if i go to recalbox's main menu\advanced settings\resolutions and choose there 720x240 - progressive 60hz, then I've got wrong picture - more stretched vertically in menu and too narrowed vertically in games wih overlays for 16x9 tv ( I've use standard old 4x3 crt tv).

How could to fix it?
