Bourn's patch for the map editor, allowing you to create maps of any size:

It doesn't seem to work on WOF 3.58f or SOD.

Yeah, but what's the point if it can't generate a map of the desired size? Manually creating it is tedious, and there's no element of randomness because you'll learn the entire map inside and out.

The bad thing is that you can't even generate small maps and then insert them into a larger map, refining them.
