Just saw this post and i will try to get an answer to my question here since it seems more people knowing the issue is gathered around here.
here is what I am trying to achieve:
OVER COMPOSITE, allow emulation station AND Kodi to run in interlaced ntsc (sdtv 0) but run emulators in progressive ntsc (sdtv 16).
Config.txt is set to interlaced, but i cant make emulators to start using any global.videomode setting in recalbox.conf (tried "NTSC 4:3 P", no good, it doesnt start).
What should I do?
