@War Lord might have the 1.xx code. Jeremy would too, I would think, if you want to send him a PM. It's pre-allegro *.cc code though, and it may not cross anyway. With enough work, it would be possible, but how man quests are in pre 1.84 format that anyone needs/wants to load?
We could make it a minor 2.60 goal, but I cannot say what the result might be. We would need to make a wholly different loading routine. Did 1.0x quests load in 2.10?
