VGA to CGA converter on a 25" Wells Gardner 25K7191
I am building a MAME cabinet out of a NEO GEO MVS cabinet. It has a Well Gardner 25" monitor. I bought a VGA to CGA converter board from China. It has 5 RGBS pin out on it and I tried matching the pattern and connected it to the board of the Wells. I get a picture but it is all wiggly and not straight. I can read stuff on the monitor though and it is the right color. I guessed on the pins because I received no documentation. Maybe I have a sync pin mixed up?
