Those GI wires will go to the “interconnect board” will need to be repaired. Alternatively, Great Lakes Modular makes new interconnect PCBs for $110 but they are unique for every game and you need to tell them what game it’s going in.

I would at least replace the burn connector because replacing the board will likely not completely resolve your problem.

Repairing the interconnect is not too hard, but you will probably need to repair traces on the COMPONENT side of the board when you replace the header pin connector on the right side. This often requires “stitching” top and bottom traces back together.

Well, looks to be so. Oh well, repairing the original is not too bad. Just follow my instructions or, if you want, I can repair it for you.

There you go, I knew someone made replacements. It’s fairly obvious the OP wanted to make the game as close to original as possible. Repairing hacks and such was understood to me.
