How to make the Editor work with extracted arcs?

[mimimi]

I've extracted all the arcs for easy modding. With the options.txt entry "use archives = false" the game runs fine. The Art Manager does too. But the Editor refuses to show the (game's decompiled) map. There's just a black window. With the arcs in place, the map shows fine. So I assume the editor is looking for arcs.

How can I tell the Editor to not use archives?

Is there a config file I can make, or do I need to hex-edit the Editor itself?
If so, what do I need to change exactly?
Does anyone know?

nargil66 gave me the idea:

moving all extracted arc folders to the database folder of the game will let the editor pick up on the assets and display the world map!

SOLVED!
