The legal status is a lot clearer now that Strife: Veteran Edition has been released. Remove the "New in v2.0 Release" section as this is unlikely to be kept up to date, and these updates are covered by the NEWS file that serves this purpose.

* 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.
