Heretic Save Game Editing FAQ by Strider VM
Version 1.0
Q. What is Hex Editing ?
A. Hex editing is changing values of a certain file in order
to cheat in games.
Q. How does it happen?
A. Most games have the option of having able to save the game. And since
save games lists the level you are on, items, keys, etc. editing
values would enable you to cheat.
Q. How does this FAQ be able to help me?
A. This is a guide on what values (Or part of the file) to change
to be able to modify a part of the save game. (Like weapons,
items, keys, etc.)
Disclaimer :
Since this thing is about modifying files, I am NOT RESPONSIBLE
for any damage this FAQ might cause. (Either your fault or just plain
wrong spelling :) So make sure to backup your files before doing any
modifications.
Now that thing out of the way, let's get started, shall we.....
What do you need in order to hex edit :
Of course, a hex editing program!
Something like Norton Disk Editor / XE etc.
What to Hex Edit :
Of course a Heretic save game file. (I think it's obvious enough.)
How to Hex Edit:
This is an explanation of how to hack Heretic save game files. First off,
you will need a hacking program. Open it up and open a Heretic Save Game.
Then there are 8 columns of 4 digit numbers (or, to be more exact, 16
columns of 2 digit numbers with spaces after every second set of 2 digit
numbers). Those are the things you alter. Ignore the stuff to the right
of that. On the status bar (the bar at the bottom of the hex
editor) you will see a thing which says offset: then an 8 digit number.
That is the place in the code your cursor is located. My hacking list
is divided into two sections, places in the code and things to put into
places in the code. If you want to edit the health , it should
read 60, so go to to byte 60 and change the value.

Extra Note :
The modifiers in the inventories, there is one that is not
completed, I think. (04) , don't use it since it might produce
side effects, just try it if you're too curious.
