Chocolate Strife is the most accurate and complete recreation of Rogue Entertainment’s “Strife: Quest for the Sigil.” It was created through more than four years of reverse engineering effort with the blessings of the original programmers of the game. ## Why? 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. Tools such as IDA Pro have been employed to disassemble and decompile the executable, which was 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. ## Is it Legal? Chocolate Strife was originally reverse-engineered from the DOS Strife binaries. Although reverse engineering is legally a protected activity, this nonetheless left some open questions about its legal status. In 2014, a new commercial release of Strife was published (Strife: Veteran Edition) based on the Chocolate Strife code, and developed by the authors of Chocolate Strife under commercial license. The release of Strife: Veteran Edition, along with its GPL-licensed source code, constitutes tacit approval for the legal status of Chocolate Strife by its current copyright holder. ## Is it Perfect? Almost, but not entirely! That’s where you come in. Help us by reporting any discrepancies you may 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. ## What are some known problems? The demo version is *not* supported, and there are not any current plans to support it in the future, due to the vast number of differences (the demo version of Strife is based on an earlier version of Rogue’s codebase). The commercial Strife IWAD version 1.1 may run, but also exhibit issues. Like the demo version, there are no current plans to fully support it. Make sure your copy is updated to at least 1.2. Strife: Veteran Edition already includes the required version. ## How do I use it? From the Run box or a command line, issue a command to Chocolate Strife just like you would run Chocolate Doom. Most of the same command line parameters are supported. voices.wad will be read from the same directory as the IWAD, if it can be found. If it is not found, then voices will be disabled just as would happen with the vanilla executable. Do not add voices.wad using -file, as that is redundant and unnecessary. Some new command-line parameters in Chocolate Strife include the following: - -nograph - Disables the graphical introduction sequence. -devparm implies this. - -novoice - Disables voices even if voices.wad can be found. - -work - Enables Rogue’s playtesting mode. Automatic godmode, and pressing the inventory drop key will toggle noclipping. - -flip - Flips player gun graphics. This is buggy, however, because it does not reverse the graphics’ x offsets (this is an accurate emulation of the vanilla engine’s behavior). - -random - Randomizes the timing and location of item respawns in deathmatch, when item respawning is enabled. ## Copyright This program is free software; you can redistribute it and/or modify it under the terms of the GNU General Public License as published by the Free Software Foundation; either version 2 of the License, or (at your option) any later version.
