.DAT? Wth?

I haz a question. Mah question iz: How in the hell do you open and edit the map textures from WORLDS? How do you open fking .DAT files?

I once had this question. then forgot abt it lol.

You can't.

Yes, you can. How else did people make the lego death room, and wood valley, and wood seed. So yes, you can. But how do you open .DATs?
