- How to Cheat in Doom
- --------------------

- March 25, 1994
-
- Greetings. I am required to upload something non-illegal to the BBS to retain my
- downloading privledges. I think this will be valuable enough to keep me in fair
- standing. I downloaded the shareware version of Doom about a week ago. I was
- very very impressed. This game breaks new boundaries in groupware gaming. This
- game is much more cool than Spectre (vector graphics don't do much for me). I
- will probably register the game soon.
-
- I played the game in net mode and then played some in one player mode. I was in
- the easy mode and was basically addicted to the game. At the end of the game, I
- was killed several times by something which I won't mention to spoil your fun. I
- then decided to pull out my disk editor and see if I could do something about
- this travesty of events.
-
- Doom and the latest series of games has the cool feature of saving a game in
- progress. This little feature allows the user to do some maintenance on his/her
- body while not losing precious points (the game also has a pause function, but
- some people may actually have a life). Well, when you save a game it makes a
- neat file called DOOMSAVx.DSG where x is 0 - 5 for the 6 different save areas.
- The files are ascii files that may be edited with a disk editor (Norton is the
- tool of choice for me).
-
- After scouting around and basically plugging and chugging, and using some
- methods that I have developed (an example is to save a character with as many
- unique numbers as you can i.e. Ammo of 94, Health of 42, Shells of 49, etc) I
- was able to find out where certain values were stored, so that I can, how shall
- I put this... be able to dominate, decimate, and destroy everything in the game
- (including my net partner ... no matter).
-
- The values are stored in Hex and are byte reversed from normal appearance. An
- example of this would be:
-
- My Ammo Number is oh I don't know - 999. In hex 999 is 3E7. Breaking that into
- bytes would make it 03 E7. The byte reversal would display it as E7 03.
-
- The following are the locations of the various options in the game. I basically
- start them off with E7 03 myself:
-
- Armor - Offset 86 - 87 - Armor will allow you to go past 999.
- Health - Offset 82 - 83 - Health will work at 999, but if you pick up any
- kind of health bonus your level will drop to 199 and
- will not go past it. Could not locate the max
- setting for that. Also, you can still die will mega
- health if you do something stupid like fire a rocket
- point blank at something.
- Rockets - Offset 214 - 215 - Amount of Rockets you have
- (number)
-
- Rockets - Offset 230 - 231 - Amount of Rockets you can have
- (maximum)
-
- Cell - Offset 210 - 211 - Amount of Cells you have
- (number)
-
- Cell - Offset 226 - 227 - Amount of Cells you can have
- (maximum)
-
- Shells - Offset 206 - 207 - Amount of Shells you have
- (number)
-
- Shells - Offset 222 - 223 - Amount of Shells you can have
- (maximum)
-
- Ammo - Offset 202 - 203 - Amount of Ammo you have
- (number)
-
- Ammo - Offset 218 - 219 - Amount of Ammo you can have
- (maximum)
-
- Also, now that you have maxed out your supplies, you will need the hardware to
- go with it. Here are the Offsets of the weapons, just put an 01 in the byte and
- the weapon will come to life (although I activated weapons 6 and 7, they would
- not come to life, and I do not know why. I speculate it is because I do not have
- the regular version):
-
- Weapon 1 - Hands - Offset 170 - Always defaulted to 01
- Weapon 2 - Handgun - Offset 174 - Always defaulted to 01
- Weapon 3 - Shotgun - Offset 178
- Weapon 4 - Machine Gun - Offset 182
- Weapon 5 - Rocket Launcher - Offset 186
- Weapon 6 - Cellular Weapon ??? - Offset 190
- Weapon 7 - ??? - Offset 194
-
- I have no idea of where the chainsaw is hiding.....
-
-
- You can save game whenever you lose something important and fix yourself up
- again. Important note: Do not use your disk editor on a stacked or compressed
- hard drive. Your best bet is to copy the file to a floppy and edit it where you
- know you will not have any problem and you cannot hurt anything.
-
- I did not bother going about finding where treasure, computer map, chainsaw, or
- the keys are located. You have to leave something to attain.
-
- Then to use your game, just go into Doom and Load game. Select the game that is
- the one you modified and voilla.
-
- You can have more fun by checking out other pieces of the file, but I got past
- the point I wanted to and finished the shareware version.
-
- For those of you who do not have the means, skill, or time to make a mega -
- character. I have made three (easy, medium, hard settings) starting at the
- beginning of the game. Just copy the files into your DOOM directory and load
- them at your leisure. Note - if you have a game in progress make sure that you
- do not copy these files over it:
-
- DOOMSAV1.DSG - Hard
- DOOMSAV3.DSG - Easy
- DOOMSAV4.DSG - Medium
-
-
- I want to thank the authors of this most cool game for enlivening my miserable
- existance for a while.
