* What is it? *
|
|
|
|
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 a much earlier beta version of Rogue's
|
|
codebase). You should use a commercial Strife IWAD file, preferably of
|
|
version 1.2 or later.
|
|
|
|
|
|
* 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.
