Hello!

How could now get progressive scan mode ( 240p) with composite cable on crt???

Ok, in previous versions of recalbox it could be done by adding line:
sdtv_mode=16 ( instead default sdtv_mode=1 , as interlace) in recalbox-user-config.txt

So, when i do it now (sdtv_mode=16), i've got wrong resolutions:

So, ask again - how could fix it??
