@mad The PAL color inversion is a very easy trick, just change line evenness in $FF1C-1D and get it. Plus4emu supports this - there was a minor error in the emulation but it works for most cases. Every line for a PAL picture has color information (burst) and for odd and even frames it is created in a different way. When we change the line evenness this forces the TED to think that it must generate the color signal for another evenness.
@gerliczer Thank you. I have only slight doubts about the TED inability to generate a proper V-sync. We need exact information in what way even and odd PAL frames differ.
