I have some software you can use, though it will probably require VirtualBox and an older OS to play. I think it was programmed for DOS. But it works if you're willing to put forth the effort. Or if you prefer, you and your dad can construct a simple set and play at home while I follow along electronically here. It only requires two sets of shogi pieces (which I have made out of simple bakeable clay) and the appropriately sized grid of hexes.
