[Coco] So is this a G board?

[Retro Canada]

found a game that is not runnig: keys of the wizard. could it be related to the pia mod? could the pia mod be the culprit for superide hang?

how do i undo it there is a trace cut close to the VDG ( after the wire is hooked)

so i remove the wire, unbend the pia pin and about the trace cut? how to restore it? make a wire connecting it to the final destination?
