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. At the time DeHackEd was released, Doom was a closed-source program, and thus to allow new features to be made available, the only choice was to patch the executable (as opposed to being able to change the source, which can now be done since id Software has made public a release of the sources). 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.

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.
