What is a .DEH file?
A .DEH file is a special kind of file called a DeHackEd Patch. It's used to change how the classic video game Doom plays. Think of it like a custom update or mod that you can apply to Doom to make it different from the original game. This could include changes to how fast the player moves, how enemies behave, or what the weapons do.
Back in the day, to make these changes, people used a program called DeHackEd, which worked on old DOS computers. The .DEH file would contain either binary data (which is like the basic language computers understand) or text data with instructions on how to change the game.
Nowadays, .DEH files are often used alongside .WAD files. A .WAD file is another type of file for Doom that can include new levels, graphics, sounds, and more. By using both .WAD and .DEH files together, people can create entirely new experiences in Doom.
To open and use .DEH files, you can use modern programs like GZDoom or SLADE. These programs let you play Doom with the changes the .DEH file adds. There are also specific editors like WhackEd4 for creating or modifying .DEH files. While the original DeHackEd program is no longer updated, these newer tools offer more features and work on current operating systems.
So, if you're interested in customizing Doom, you might look into using a .DEH file with one of these programs. Whether you're playing with mods others have made or trying to create your own, these tools will help you get started.
