James Hughes		 415 DNCE is the only 32bit Windows Duke Nukem source con editor available. It introduces a friendly and effective, visual IDE (Integrated Development Environment) way of editing Duke Nukem *.con files - resembling closely to the screen of modern HTML source editors.

DNCE is designed for editing *.con files, and it has many features that will make con hacking, testing and Duke launching easy, as opposed to some of the often used editors, such as WordPad (Windows) or Edit (DOS).

  • file size is not limited
  • built-in Duke and Build launcher - test your work in a snap!
  • syntax checking
  • configurable color coding of primitives
  • primitives list - point and click to insert
  • built-in calculator - convert count ticks to seconds and vice versa

WDiff  v1.49
Chris Sitte		 197 Windows File/Directory Difference Viewer.

  A Windows(3.1/95/98) application which displays the differences between two text files(Cons) or between two directories or ZIP archives.

Side by side display of two text files, directories or ZIP archives. Useful for programmers to see the differences between two source text files or two sets of files, where one or both sets can reside in a ZIP archive. Line editing functions.

Common and different sections are clearly marked with separator lines and different colors. The display window is scrollable in all directions. The middle line which separates the two sides can be moved in either direction to see more of the left or right side.

It is also possible to jump between common and different sections. This utility is especially useful for programmers who want to see the differences between two versions of a source text file or to show the differences between two sets of files, where one or both sets can reside in a ZIP archive. There are various formatting and comparison options available.

  -I use this program to compare two cons files, the original stock Cons and the modified Cons. It will show precisely where the modifications are in them at line numbers. Very useful to learn Con hacking/modding and to track down any errors.  -Corv

CONtrol
James Ferry		 65.6 This util optimizes the con files the same way Duke3D does just before a game is run. All CONs are merged with one complete con file. (This was once used back in the day by a few TC makers to try to hide/compress, or close your CON code to others.)

Note: An updated version is built into the 'OpenGL Build Touch tool' found in the 'duke3d-tools-build' download section.
