Universal Do Run Run

I bought an untested PCB online and I know untested means may not work. I wanted it because it's original I think. She powers on, sound seems to work.

Game starts but I can't move up, or fire.

Any ideas on what to look at? I'm using a MAS Supergun and everything works with other games fine

Also any idea what this little adapter is soldered on to the connector? There's a small white connector attached to the PCB.

I went into test mode. All ROMS test ok.

Next screen shows colors. It's missing Green completely and one bar of blue.

Next screen is control test. Players 1 and 2 do not move up, but other directions fine. Player 1 fire button doesn't work.

Forgot I had Deoxit. Cleaned the edge connector. Joystick works fine. I can play. Green color is back, however now sprites are corrupt. I have yet to clean the chips yet.
