Just a quick post to let you know I got a small Minecraft -> DScraft map converter working. It's extremely early but it works in most situations. To use it, just download it here :
http://smealum.net/dscraft/mc2ds.exe , place the "region" folder from your Minecraft save in the same folder and run mc2ds.exe ; it should spit out a testmap.map file.
Again, this is extremely early and is probably buggy, you can't choose which part of the map you want to convert and it doesn't support torches and in their current form maps generated this way are likely to crash DScraft (at least current version, it's been "fixed" already), especially if they include large bodies of water. So you have been warned, don't complain about it because I honestly couldn't care less at this point.
But once the converter works properly, that means one could probably use programs like MCedit for DScraft.
