ADiKtEd is one of three existing editors for DK1 maps. Others are UnDed and Official (Bullfrog) Editor, but ADiKtEd is the most featured and advanced.
ADiKtEd is a console program, but all the map editing routines are closed in Dynamically Linked Library, so it's possible for programmers to writa a GUI for it.
