In another hat I am helping to develop Dungeon Craft, an update to FRUA - Forgotten Realms Unlimited Adventures.
Pictures and interactive conversations are two of its strong points. And it is modeled after D&D 1st edition for the most part. And it includes a LOT of easy scripting possibilities. Not like DSAs

I don't really know what it is you folks are talking about in this thread but the words make me think that DC might be of help.
