Cool! I uploaded a scan of the D&D playfield. The printed part is glued onto a folded plastic piece with conductive traces, like a lot of games. I tried to remove it, but it's stuck on so well that it was pulling off the paint, so I scanned it as-is. That means you can see some of the traces through the printing, but that's how it really is. The case covers up a lot of it anyway- just the centers of each square are visible.
D&D is interesting; just 72 buttons and a speaker. But it's another one of those electronic games with pieces, which makes it more difficult to emulate in MESS.
