HACKING CTP: TIPS FROM ACTIVISION
How to edit the Great Library, Sounds, and Sprites
GREAT LIBRARY:
If you want to edit or create your own text entries for
anything in the Great Library, you must first decide
which type of entry (Unit, Wonders, etc.) you wish to
change. To find the filename used in the Great
Library, open the respective *ICON.TXT file in
\CTP_DATA\DEFAULT\GAMEDATA\. For
example, open UNITICON.TXT to find the filenames
used by the Legion (Unit) in the Great Library.
Each item in the *ICON.TXT files has several
filenames associated with it. The .TGA is used for
the still image. The .AVI is used for the rotating
image. The .TXT files beginning with "GAME" are
displayed in the Gameplay section of the Great
Library. The .TXT files beginning with "HIST" are
displayed in the Historical section of the Great
Library. The .TXT files beginning with "PREQ" are
displayed in the upper-left section of the Great
Library. The .TXT files beginning with "VARI" are
displayed in the upper-right section of the Great
Library. The .TXT files beginning with "STAT" are
displayed to describe the gameplay features of the
item in the Production Tab.
Once you have found the proper filename, you may
create your own file using the same file type and
filename as the original. Create .TGA using 160x120
pixel size. Create .AVI files with 160x120 pixel size
(use 15 frames per second and Indeo 5.10
compression for best results). After creating your file,
place it in the proper directory to be used in the
game. Place .TGA files in
\CTP_DATA\DEFAULT\GRAPHICS\PICTURES.
Place .AVI files in
\CTP_DATA\DEFAULT\VIDEOS. Place .TXT files
in \CTP_DATA\ENGLISH\GAMEPLAY\GL. The
original files are stored in the .ZFS files. Do not try to
change or open those files. Any file outside of a .ZFS
has priority and will be used instead of the original.
To revert back to the original files, simply delete your
files.
SOUNDS:
If you want to create your own sound files for Units,
you must first decide the action and filename for
which you wish to create a .WAV file. Refer to the
SOUNDS.TXT in
\CTP_DATA\DEFAULT\GAMEDATA\. Each Unit
has several sounds, one for each of the actions that
the Unit may perform. Match the Action and Unit to
find the filename. For example, to learn the .WAV
filename used for the Death of a Legion, open
SOUNDS.TXT and search for "Legion". The
filename "GUVV78.wav" is listed after the entry
reading "SOUND_DEATH_LEGION."
Some items have different names than those
displayed in the game. For example, the Mounted
Archer Unit appears as "Chariot" in the text files.
To use your own .WAV file, name your file the same
as the filename found in SOUNDS.TXT. Then place
your .WAV in \CTP_DATA\DEFAULT\SOUND.
The original .WAV files are stored in the
"SOUND.ZFS" file. Do not try to change or open
that file. Any file outside of the .ZFS has priority and
will be used instead of the original. To revert back to
the original files, simply delete your files. Use 22mHz,
16bit mono when creating .WAV files.
UNIT SPRITES:
To change the sprite used for a Unit, open
SPRITEID.TXT, which is located in
\CTP_DATA\DEFAULT\GAMEDATA. Then you
decide on two things. First, decide which Unit you
wish to change. Then decide which other Unit's sprite
you wish to replace with the first Unit. Simply change
the number of the first Unit to the same number listed
after the second Unit. You should write down the
original number of the Unit you are changing so that
you can change it back at a later time.
