Chocolate Doom installation
|
||
|
|
===========================
|
||
|
|
|
||
|
|
These are instructions for how to install and set up Chocolate Doom
|
||
|
|
for play.
|
||
|
|
|
||
|
|
Obtaining an IWAD file
|
||
|
|
----------------------
|
||
|
|
|
||
|
|
To play Doom, you need an IWAD file. This file contains the game data
|
||
|
|
(graphics, sounds, etc). The full versions of the Doom games are
|
||
|
|
proprietary and need to be bought. The IWAD file has one of the
|
||
|
|
following names:
|
||
|
|
|
||
|
|
doom1.wad (Shareware Doom)
|
||
|
|
doom.wad (Registered / Ultimate Doom)
|
||
|
|
doom2.wad (Doom 2)
|
||
|
|
tnt.wad (Final Doom: TNT: Evilution)
|
||
|
|
plutonia.wad (Final Doom: Plutonia Experiment)
|
||
|
|
chex.wad (Chex Quest)
|
||
|
|
|
||
|
|
If you don't have a copy of a commercial version, you can download
|
||
|
|
the shareware version (extract the file named doom1.wad):
|
||
|
|
|
||
|
|
* http://www.doomworld.com/idgames/index.php?id=7053
|
||
|
|
(idstuff/doom/win95/doom95.zip in your nearest /idgames mirror)
|
||
|
|
|
||
|
|
If you have a commercial version, obtaining the IWAD file is usually
|
||
|
|
straightforward. The method depends on how you obtained your copy of
|
||
|
|
the game:
|
||
|
|
|
||
|
|
* The Doom games are available to buy for download on Steam
|
||
|
|
(http://www.steampowered.com/). To find the IWAD files on a
|
||
|
|
Windows system, look in the Steam directory (usually within
|
||
|
|
"Program Files"), under the "steamapps/common" path.
|
||
|
|
|
||
|
|
* There have been several CD-based versions of Doom. Generally, the
|
||
|
|
IWAD files can be found on the CD and copied off directly.
|
||
|
|
|
||
|
|
* If the IWAD files are not directly available on the CD, or you have
|
||
|
|
a floppy disk version, installation is more difficult. The best
|
||
|
|
suggestion is to use a DOS emulator (such as DOSbox) to run the
|
||
|
|
installer.
|
||
|
|
|
||
|
|
* As an alternative to using an emulator, it is possible to extract
|
||
|
|
the files manually. On the install disk(s), you will find several
|
||
|
|
files with numbered extensions (with CD versions there may be a
|
||
|
|
single large file with the extension .1, eg. "resource.1").
|
||
|
|
|
||
|
|
From the command line it is possible to combine these files into a
|
||
|
|
single large file, using a command similar to the following:
|
||
|
|
|
||
|
|
cat doom_se.1 doom_se.2 doom_se.3 doom_se.4 doom_se.5 > doom_se.lha
|
||
|
|
|
||
|
|
The resulting file is an LHA archive file, and it can be extracted
|
||
|
|
using an LHA archive tool (there is one available for almost every
|
||
|
|
operating system).
|
||
|
|
|
||
|
|
Running the game
|
||
|
|
----------------
|
||
|
|
|
||
|
|
Chocolate Doom needs to know where to find your IWAD file. To do this,
|
||
|
|
do one of the following:
|
||
|
|
|
||
|
|
* Run Chocolate Doom from the Unix console with the '-iwad' command
|
||
|
|
line parameter to specify the IWAD file to use, eg.
|
||
|
|
|
||
|
|
chocolate-doom -iwad /root/doom2.wad
|
||
|
|
|
||
|
|
* Put the file into one of the following directories:
|
||
|
|
|
||
|
|
/usr/share/games/doom
|
||
|
|
/usr/local/share/games/doom
|
||
|
|
|
||
|
|
* Set the environment variable DOOMWADDIR to specify the path to a
|
||
|
|
directory containing your IWAD files.
|
||
|
|
|
||
|
|
* If you have multiple IWADs in different directories, set the
|
||
|
|
environment variable DOOMWADPATH to be a colon-separated list of
|
||
|
|
directories to search (similar to the Unix PATH environment
|
||
|
|
variable).
|
||
|
|
|
||
|
|
Playing with Chex Quest
|
||
|
|
-----------------------
|
||
|
|
|
||
|
|
Chex Quest is a game based on Doom with some minor modifications that
|
||
|
|
was distributed with boxes of Chex cereal in 1997. It is possible to
|
||
|
|
play Chex Quest using Chocolate Doom. To do this, the following files
|
||
|
|
are needed:
|
||
|
|
|
||
|
|
* The IWAD file 'chex.wad', from the Chex Quest CD.
|
||
|
|
|
||
|
|
* The dehacked patch 'chex.deh', which can be found here:
|
||
|
|
http://www.doomworld.com/idgames/?id=15420
|
||
|
|
(utils/exe_edit/patches/chexdeh.zip in your nearest /idgames mirror)
|
||
|
|
|
||
|
|
Copy these files into a directory together and use the '-iwad' command
|
||
|
|
line parameter to specify the Chex Quest IWAD file:
|
||
|
|
|
||
|
|
chocolate-doom -iwad chex.wad
|
||
|
|
|
||
|
|
Installing upgrades
|
||
|
|
-------------------
|
||
|
|
|
||
|
|
Chocolate Doom requires a version 1.9 IWAD file. Generally, if you
|
||
|
|
install a recent version of Doom you should have a version 1.9 IWAD.
|
||
|
|
However, if you are installing from a very old CD version or from
|
||
|
|
floppy disks, you might find you have an older version.
|
||
|
|
|
||
|
|
The most obvious symptom of an out of date IWAD file is that the game
|
||
|
|
will exit at the title screen before the demo starts, with the message
|
||
|
|
"Demo is from a different game version!". If this happens, your IWAD
|
||
|
|
file is out of date and you need to upgrade.
|
||
|
|
|
||
|
|
Id Software released upgrade patches that will update your game to
|
||
|
|
version 1.9. The following sites have the patches:
|
||
|
|
|
||
|
|
http://www.doomworld.com/files/patches.shtml
|
||
|
|
http://www.doom2.net/doom2/utils.html
|
||
|
|
ftp://ftp.idsoftware.com/idstuff/doom2
|
||
|
|
|
||
|
|
As the patches are binary patches that run as DOS executables, you
|
||
|
|
will need to use a DOS emulator (such as DOSBox) to run them.
|
||
|
|
|
||
|
|
Music support
|
||
|
|
-------------
|
||
|
|
|
||
|
|
Chocolate Doom includes OPL emulation code that accurately reproduces
|
||
|
|
the way that the in-game music sounded under DOS when using an
|
||
|
|
Adlib/Soundblaster card. This is, however, not to everyone's taste.
|
||
|
|
|
||
|
|
As an alternative it is possible to use Timidity for high quality MIDI
|
||
|
|
playback:
|
||
|
|
|
||
|
|
http://timidity.sourceforge.net/
|
||
|
|
|
||
|
|
A good set of patches for Timidity is the eawpats collection, which can
|
||
|
|
be found here:
