Hello!
I use Raspberry pi 4 connected via composite to old crt-tv.
But i have a problem with running recalbox in NTSC mode (sdtv_mode=0 in config.txt).
My tv has 4 color modes: pal, secam, ntsc 4.43, ntsc 3.58.
So when i set ntsc 4.43 on tv - i've got "wrong" colors in recalbox ( green not green, purple not purple and etc.... ).
When i set ntsc 3.58 - i'v got just black-white-colored picture on display.

When run in PAL (sdtv_mode=2), all colors are fine, but i didn't want to play at 50hz, that's equaled 50 fps by emulators and all my roms are NTSC.

When i'v set pal 60 (sdtv_mode=3 in config.txt) - got black-white-colored picture too. But my tv has 60hz support:

So, i've need some "color fix" ....

As example, for retropie i've found this solution: twekwec and it's worked! But it's need phyton installed on the system. so it's unable on recalbox....
