SYNOPSIS
chocolate-strife [OPTIONS]DESCRIPTION
Chocolate Strife is an accurate and complete recreation of Rogue Entertainment's "Strife: Quest for the Sigil". It was created through more than two years of reverse engineering effort with the blessings of the original programmers of the game (see the section HISTORY below).

- -deh <files>
- Load the given dehacked patch(es)
- -merge <files>
- Simulates the behavior of deutex's -merge option, merging a PWAD into the main IWAD. Multiple files may be specified.
- -nocheats
- Ignore cheats in dehacked files.
- -nwtmerge <files>
-
Simulates the behavior of NWT's -merge option. Multiple files may be specified.
ENVIRONMENT
This section describes environment variables that control Chocolate Strife's behavior.- DOOMWADDIR, DOOMWADPATH
- These environment variables provide paths to search for Doom .WAD files when looking for a game IWAD file or a PWAD file specified with the `-file' option. DOOMWADDIR specifies a single path in which to look for WAD files, while DOOMWWADPATH specifies a colon-separated list of paths to search.
- PCSOUND_DRIVER
- When running in PC speaker sound effect mode, this environment variable specifies a PC speaker driver to use for sound effect playback. Valid options are "Linux" for the Linux console mode driver, "BSD" for the NetBSD/OpenBSD PC speaker driver, and "SDL" for SDL-based emulated PC speaker playback (using the digital output).
- OPL_DRIVER
-
When using OPL MIDI playback, this environment variable specifies an
OPL backend driver to use. Valid options are "SDL" for an SDL-based
software emulated OPL chip, "Linux" for the Linux hardware OPL driver,
and "OpenBSD" for the OpenBSD/NetBSD hardware OPL driver.
Generally speaking, a real hardware OPL chip sounds better than software emulation; however, modern machines do not often include one. If present, it may still require extra work to set up and elevated security privileges to access.
FILES
- $HOME/.chocolate-doom/strife.cfg
- The main configuration file for Chocolate Strife. See strife.cfg(5).
- $HOME/.chocolate-doom/chocolate-strife.cfg
- Extra configuration values that are specific to Chocolate Strife and not present in Vanilla Strife. See chocolate-strife.cfg(5).
HISTORY
The source code for Strife was lost, which means, unlike the code for all the other commercial DOOM-engine games, it cannot be released. The only access we have to the code is the binary executable file. Reverse engineering tools were employed to disassemble and decompile the executables, which were cross- referenced against the Linux DOOM and DOS Heretic sources and painstakingly combed over multiple times, instruction-by-instruction, to ensure that the resulting Chocolate-Doom-based executable is as close as possible to the original.
LEGALITY
Reverse engineering is a protected activity so long as the original code is not used directly in the product. Due to the vast amount of information lost through the process of compilation, and the need to refactor large portions of code in order to eliminate non-portable idioms or to adapt them properly to Chocolate Doom's framework, the resulting code behaves the same, but is not the *same* code.In addition, James Monroe and John Carmack have both stated that they have no objections to the project. Because they are the original authors of the code, and neither Rogue nor their publisher, Velocity, Inc., exist any longer as legal entities, this is effectively legal permission.
BUGS
Chocolate Strife is almost, but not entirely perfect, in recreating the behavior of Vanilla Strife. Help us by reporting any discrepancies you might notice between this executable and the vanilla DOS program.However, do *not* report any glitch that you can replicate in the vanilla EXE as a bug. The point of Chocolate Strife, like Chocolate Doom before it, is to be as bug-compatible with the original game as possible. Also be aware that some glitches are impossible to compatibly recreate, and wherever this is the case, Chocolate Strife has erred on the side of not crashing the program, for example by initializing pointers to NULL rather than using them without setting a value first.
AUTHORS
Chocolate Strife is part of the Chocolate Doom project. It was reverse engineered from the DOS versions of Strife by James Haley and Samuel Villarreal. Chocolate Doom was written and maintained by Simon Howard, and is based on the LinuxDoom source code released by Id Software.COPYRIGHT
