I am doing the same thing with the exact same japanese mega drive board that has the CXA1145 in reverse.

I can’t get the sync to work! There is no video also if I use a composite video cable.

Added a resistor from blue pin 29 to cysnch. I also removed a capacitor on the other end of the resistor.
