Hello arcade fanatics

I am tryin to finish up my mspacman galaga cab and the only thing really needed to polish it off is a cpo other than the original mint mspac overlay I had..
I wanna add buttons to the game.... well heres the control panal im using...
original midway panal with a 3" trackball hole in the middle..
some start buttons over on the far left.. between the Tb and s/btns 3 action buttins..
over on the far left I will mount a joystick.. what kind dunno.. doesnt really matter

Lemme grab a real pic with measurements of the actual cp.
But i was gona try for half black and mspac blue on the left .....
the rest will come lata
thx
