DOOM Text Edit v2.11 by Dylan Hicks. This interesting program allows you to make changes to the DOOM(1UD2).EXE file. It can edit the text data, variable markers, and all the cheat codes. The text data DTEDIT accesses is the data that DOOM uses when it displays game messages, error messages, and verification messages. It creates an entry table file (.ETF), which contains all of your changes, that you can load into the DOOM.EXE from the command line. Terrific for theme-based conversion projects.

DM2CONV v3.2 by Vincenzo Alcamo. This is a great little program! it converts any PWAD from one game version to another: DOOM to DOOM II, DOOM to HERETIC, HERETIC to DOOM or II, and back. But more than that, it uses response files to specify texture (and other resource) changes. You could do mass texture and flat changes in your level, since DM2CONV also converts to the same format: i.e., D2 to D2, D to D, H to H, etc. As you know, DOOM crashes if it comes across an invalid texture name. I had a level that did this and I could not find the texture in an editor. Using DM2CONV I simply converted the problem texture to a valid one. Also does object substitution, resource renaming, LineDef/Sector types remapping, music/sound remapping, and more. Also comes with GFXMAKER which creates a texture WAD from any IWAD. Works with Ultimate DOOM. Excellent documentation, easy to use.
