Command.txt exploit

The Command.txt is a text file placed in the Diablo I: Hellfire directory that enables the player to unlock the hidden characters, quests, and multiplayer mode.

A few steps are required to enable it, and the other secret features in Hellfire.

Unlocking the Undocumented Features
First, you must have Hellfire installed on your machine before any of the following will work. So, having Diablo I installed is mandatory.


 * 1) Download this file (640k, zip) hosted by the Unofficial Diablo Site. It contains:
 * Sierra's official Hellfire v1.01 patch (also can be downloaded directly from the Sierra site).
 * The hacked hellfrui.dll you need to enable multiplayer in Hellfire v1.01.
 * The command.txt file.


 * 1) Open the zip
 * 2) OPTIONAL: run hf101.exe to upgrade to the Hellfire v1.01 patch. This will not work on 64-bit versions of Windows due to complicated reasons related to CPU architecture, the difference between emulation and virtualization, and the fact that the installer is a 16-bit Windows program rather than a 32-bit one.
 * 3) Extract hellfrui.dll and command.txt to your hellfire folder (C:/sierra/hellfire by default).
 * 4) The Bard,, the  quest, the Jersey's Jersey quest, and multiplayer are now enabled in your Hellfire game.

Command.txt Editing
If you wish to disable any of the features enabled by the command.txt, simply delete the mention of that item in the code. For instance, if you wanted to not include the Cow quest, because it is considered silly by many people, just remove that portion from the code, turning this:

into this:

Be sure you do not change the spacing or leave an extra semicolon. These values are checked when the program initiates, so if you wish to change something, you will have to exit Hellfire, save the change, and then restart.

Either way, all the hidden features are worth a look at and the quests are fun to complete at least once.

Individual commands
Hidden quests:
 * &mdash; teddy bear & Little Girl quest
 * &mdash; Complete Nut instead of Lester the Farmer, also changes the dialogue of Na-Krul

Hidden characters:
 * &mdash; Bard (with Rogue's graphics)
 * &mdash; Barbarian (with Warrior's graphics)

Other options:
 * &mdash; probably used in multiplayer testing; now useless, because multiplayer was removed from hellfrui.dll (you need a hacked version of it)
 * &mdash;The Festering Nest color palette is changed (from yellowish green to violet/purple)
