Through a lot of searches, I finally stumbled on sublynx's SH3 Charts Addon mod that used the maneuvering and timepiece boards. From the way it looked, I think he had it set up so that it was functional in SH3.
Does anyone know how these boards work in SH5? As it stands, you can't use any tools on them, and if we have to draw with the tools first, then line up the boards precisely over those markings, then I can't see it being useful or functional.
