.SH DESCRIPTION

|
|
.PP
|
||
|
|
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).

.SH 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.
|
||
|
|
|
||
|
|
.SH 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.
|
||
|
|
|
||
|
|
.SH 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.

.SH 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.
