NationMaster - Encyclopedia: DeHackEd

DeHackEd is an editor originally created for Doom's original EXE that allows the operation of the executable to be changed. Hit points, sounds, frame sequences, text Strings and several other miscellaneous values can be changed. Modifications can be distributed in the form of DeHackEd "patches" which can be applied to the executable.

The most common patches add fast monsters and weapons, player-seeking-self-detonating barrels, and so on. However, more balanced and artistic modifications can and have been made. Even though many advanced effects can be achieved with DeHackEd, it does not offer the complete flexibility that a custom source port can provide. Monster AI and armor classes are fixed for example. A source port is a source code modification to a computer games engine that allows it to be played on operating systems for which it was not originally created or compatible with. ...

Older DeHackEd patches use a binary format of data to be applied to an executable file using the DeHackEd patching utility. Later versions of DeHackEd save their patches in a human-readable plain text format that can be edited them with any text editor.

Boom included the ability to load DeHackEd patches and affect changes to the game upon startup without any modification to the executable file. Other source-ports added similar functionality, and command-line loadable DeHackEd support is now common with most modern source-ports. Boom also provided the BEX (Boom EXtended) extensions for DeHackEd support. BEX allows greater flexibility in string editing, application of codepointers to any frame, and extra codepointers. Boom was a port of the Doom source code by TeamTNT (who also made the Evilution level set in Final Doom). ...

Thing numbers

When modifying things in DeHackEd, each thing type has an associated number. These correspond to the index in the thing info table inside the executable (found in info.c in the Doom source code). This number is different from the number used to identify things when editing levels. Look up thing in Wiktionary, the free dictionary. ...
