- This program will modify all of your save game files for
- Wolfenstein 1 by ID/APOGEE so that you will have 100%
- health, 9 lives, and 99 ammo.
- If you don't like to start over a million times and just
- want to have some fun with this terrific game, cheat!
- I recommend that you save copies of all your game save
- files (they are named SAVEGAM?.WL1 where "?" is a number
- from 0 to 9) before running this program in case you want to
- play as a mortal again!
- Place the WOLF1CHT.EXE file in the same directory as the
- save files and enter WOLF1CHT to modify the files.
- NOTE: If you get killed, you will start back at the
- beginning of the current level. Although you will still have
- all of your remaining lives, your ammo will be reduced. If
- you want your ammo back, reload the most recent save file.
-
- SAVE YOUR GAME OFTEN!

- 6-6-92 and 12-8-92
- I changed the number of lives to 9 (the original cheat
- gave you 200 lives) because you really don't need that many
- lives.
-
- VERSION 1.1 AND 1.2 NOTES:
- The new Wolfenstein (versions 1.1 and 1.2) have a different
- save file format to help discourage cheating. If you use
- WOLF1CHT with version 1.1 or 1.2, the game will tell you
- that the save file has been altered but will let you play
- anyhow. HOWEVER, your lives will be reduced to 1, your ammo
- to 8, your score to zero, and any new weapons you found will
- vanish!
- This can be prevented by altering two bytes in the
- WOLF3D.EXE file. Once the bytes have been altered, the game
- will still say the save file was altered but it will no
- longer reduce your ammo, lives, etc!
-
- IF YOU HAVE VERSION 1.1 OR 1.2 the bytes can be altered in any
- of three ways:
-
- 1) Perhaps the easiest way is to use the ALTERWLF.BAT
- program which I have included. It uses DEBUG to make the
- changes and saves a copy of the original EXE file as
- WOLF3D.OLD so you can rename it if you want to return to the
- unaltered version.
- Make sure that both ALTERWLF.BAT and ALTERW11.SCR are in
- the same directory as the WOLF3D.EXE file and that DEBUG is
- in a directory listed in your path. Then enter ALTERWLF 11
- to modify the bytes (ALTERWLF 12 will also work).
-
- 2) The second way is to use a hex editor on the WOLF3D.EXE
- file. Be sure to make a copy of the original EXE file in
- case you make a mistake and in case you want to go back to
- the unaltered version.
- Search for the sequence C7 06 CE which you should find at
- byte 3989h. Change the C7 06 to EB 22. That's all there is
- to it!
-
- 3) You can manually use DEBUG to alter the bytes. Again, be
- sure to make a copy of the original EXE file. Also, remember
- that DEBUG cannot write changes to EXE files so you will
- have to temporarily rename the file to something else (like
- WOLF3D.ZAP).
- Load the file into DEBUG and you should see the bytes C7
- 06 CE starting at byte 3A89h. Type E 3A89 EB 22 to alter the
- bytes then enter W to write the altered file. Quit DEBUG and
- rename the file to the EXE extension.

- VERSION 1.3 NOTES:
- There is NO version 1.3! Because there was a bogus file out
- there which claimed to upgrade you to version 1.3 and then
- did nasty things to your hard drive, this version number was
- skipped.
-
- 1-5-92
- VERSION 1.4 NOTES:
- Well, There was a pre-release version which was leaked out
- early by Scott Miller of Apogee (11/92). The problem here is
- that there are actually TWO versions of Wolf 1.4 out there. They
- differ only in the address for Apogee (according to Jay Wilbur
- of ID) but also differ in the name of the main program file. The
- file is named W3D-E1.EXE for the pre-release and WOLF3D.EXE
- for the "official" release.
- > What this means for you is that if you have the pre-release
- (ie a file named W3D-E1.EXE) just rename the
- file by entering the following at the DOS prompt:
- RENAME W3D-E1.EXE WOLF3D.EXE
- or let the ALTERWLF.BAT file do it for you.
- Remember to start the game by entering WOLF3D
-
- The bytes to alter are a little bit different than the old
- ones so ...
-
- 1) To use the DEBUG script, follow step 1 above, but type
- ALTERWLF 14 and make sure that ALTERW14.SCR is in the
- same directory instead of ALTERW11.SCR (or just put them
- both there).
-
- 2) With a hex editor, search for the sequence C7 06 EA which you
- should find at byte 3985. Change the C7 06 to EB 22.
-
- 3) Same as step 3 above except that you should see the bytes
- C7 06 EA starting at byte 3A85. Type E 3A85 EB 22 to alter the
- bytes.
-
-
-
-
- DETAILS:
- For you hex fans out there who like to do things
- manually, the WOLF1CHT program works by altering the
- following bytes in the save files:
- AMMO byte 34h (52 decimal) changed to 63h (99 decimal)
- LIVES byte 30h (48 decimal) changed to 09h (9 decimal)
- HEALTH byte 32h (50 decimal) changed to 64h (100 decimal)
-
- The ALTERWLF byte changes simply insert a JMP instruction
- which causes program execution to skip over the code which
- reduces the ammo, lives, etc.
-
- HAVE FUN!
