Do you have another board to test you game out with while you work on this one? Honestly if it were me I would use it as practice and count it as a bonus if I revive it. I just had a board like this recently and the reset generator change is the way to go for this sort of board. You have to ohm out all the connections and vias when you get all the cleanup and repairs done. I had 1 via in that area not making a connection and hung up the board.
