Thank you Levente for the information! I have already noticed in plus4emu source code that the NTSC color phases are different while the standard says the color phases are rotated with 33 degree which is the case in the documentation (just the wrong direction). I will check YAPE too and use color angles from the emulators. I am investigating the color and luma signals via oscilloscope directly on the TED pins and sometimes on the composite output after the RF modulator. The luminance levels are also strange and not the same as in the documentation...
