DeHackEd v2.3
By Greg Lewis (Tree)
gregl@umich.edu
DeHackEd is capable of heavily restructuring the way Doom works. Peruse
various data tables in the Doom exe file, and modify them at will. Make
fireballs invisible, make missiles do 2000 points of damage, make demons
float! Edit the Ammo tables to help your struggling Marine with more
ammo. Edit the Frame tables, and create new looking items, or extra-fast
shooting weapons. And save your changes in patch files to distribute to
your friends. Create new types of deathmatches, with plasma "mines" and
super-fast wimpy rockets. Wad developers can modify monster types to
distribute with their levels... great new possibilities!
[ sales mode off :-]
This will probably be the last version of DeHackEd I write. I intended
to stop after version 2.2, but because Id released a new Doom version
(and I had a few tricks to program yet) I decided to release 2.3. Hope-
fully now I am done, for I have other things to do than sit down and pick
apart exe files. =-} If you want to work on DHE yourself, I can send
you the source code (see my note on source code further down). So, until
next time (Quake?), happy Dooming.
Several patch files have been included, including the latest version
of the ever popular super-rapid-fire weapons patch. A complete list of
patch files is included below. If you think you're tough, I recommend
trying the TURBO.DEH patch, and seeing how your reflexes REALLY are! Or,
if you are a deathmatch maniac (or just a sucker for single-player pain),
load up the DMARMY2.DEH patch. It's specifically designed so that you
have a hard time guessing who is a human and who is undead!
Files in this release:
DEHACKED.EXE - The executable file, version 2.3
DEHACKED.INI - The preferences file, should be in the
same directory as dehacked.exe

detailed descriptions of the editing screens
DEHACKED.TXT - This file, mostly product information
DHEFUN11.TXT - "Fun with DeHackEd" v1.1, a small tutorial
type document with fun and easy hacks
DMARMY2.DEH - Intended for deathmatch, this patch turns
monsters into Marine look-alikes
FUN_2.DEH - A patch file showing Fun with DeHackEd tricks
README.TXT - Important start-up information
SAMPLE.DEH - Demonstration/description of the new text
format patch files
SUPRWEP7.DEH - The latest super-weapons patch
TURBO.DEH - Turbo Doom... not for the faint of heart!

I've released this program to the public domain without requiring
a registration fee for a "registered" version. However I have put quite
a chunk of time into this program, and I would appreciate any donations
that you are willing to send. I estimate a suitable sum to be about $10
for my efforts. My snail-mail address is:

There was a stir about DeHackEd a few months ago in several Doom forums,
newsgroups, and the like. If you plan on creating any large masterpieces
that use DeHackEd patches and which you wish to distribute, keep in mind
that iD's legal department considers such patches illegal, and a breach of
their software license and copyright. Further conversations show that Id
is unlikely to mind much, but just remember that you should think twice
before major distribution of patches, since the law's on iD's side.
If you are interested in the code for this program, I would be more
than happy to email you a copy of it. Just drop me an email message at
the address listed at the top of this file and I'll send it your way.
DeHackEd is written in Borland C++ v3.1, although it is 95% straight C
code.

Special thanks also go out to the following people, without whose help
DeHackEd would not exist. Thanks a lot for your help, and if I've missed
you on this list, just let me know and I'll fix it immediately.

For writing Doom, so I could blow the last year on it.
Matt Fell, (msfell@aol.com)
Many thanks for the great Doom exe specs, from which DeHackEd
was born!

For some down-n-dirty messing with the Doom exe file, to find
a few of the more technical details.

Gave invaluable help with the sound code, which just plain
wouldn't work without his help (still iffy for that matter).

For writing the "Fun with DeHackEd" text file, and helping in
finding additional unknowns.
