Overview:

Amiga 68k port based on Chocolate Doom v2.3.0...includes ports of Heretic,
Hexen and Strife.

1998 saw the public release of the Doom source code by its original authors,
id Software. Since then, a large number of Doom "source ports" have been
created by programmers, who have extended the code, adding new features and
removing some of the limitations of DOS Doom (now commonly referred to as
"Vanilla Doom" by fans). These efforts should be commended, and many of the
modern Doom source ports are truly impressive pieces of work.

Chocolate Doom takes a different approach to other source ports. Its aim is
to accurately reproduce the experience of playing Vanilla Doom. It is a
conservative, historically accurate Doom source port, which is compatible with
the thousands of mods and levels that were made before the Doom source code
was released.  Rather than flashy new graphics, Chocolate Doom's main features
are its accurate reproduction of the game as it was played in the 1990s. The
project is developed around a carefully-considered philosophy that
intentionally restricts which features may be added (and rejects any that
affect gameplay).

Originally just a port of the Doom source code, the project has grown to
include ports of Heretic, Hexen and Strife, other commercial games that were
based on the Doom engine.


Requirements:

1) An RTG Amiga.
2) 68060 processor or better (PiStorm recommended).
3) AHI installed and configured.
4) CAMD library installed and configured for native MIDI playback.
5) Music packs for digital music playback (see links section below).   
6) The original games (or demos).


Configuration Options:

When running from the Shell you must specify a stack of at least 300,000.
Please see the Chocolate DOOM documentation for command line options, most of
these can be set via tooltypes.
Any errors/warnings should be written to a log file.


Limitations:

1) No network multiplayer support.
2) No Joystick support.


Version History:

2.3.0.01 - Added window mode support.
2.3.0.03 - Added native MIDI support (CAMD).
2.3.0.04 - Changed to update window even when inactive (DOOM and Strife).
2.3.0.05 - Fixed looping bug with MIDI playback.
2.3.0.06 - Updated mouse grab.
2.3.0.07 - SDL fixes for 8 bit window mode.
2.3.0.08 - Updated window mode and input capture handling.
2.3.0.09 - Updated custom WAD file handling.
2.3.0.10 - Fixed sound effects configuration.
2.3.0.12 - Added PiStorm optimized image reconstruction.
2.3.0.14 - Fixed save game issues with Strife.
2.3.0.16 - Improved the quality of the 32-bit scalers.
2.3.0.18 - Fixed minor visual bugs.
2.3.0.19 - Updated to use the latest SDL library.


Performance Considerations:

1) Fast File System is actually not, use PFS3 instead.
2) Playing OGG compressed music on a real 68k CPU will be very slow.
3) Use v4.18 of AHI as the later versions are too slow.
4) Image scaling will add an additional overhead, this includes enabling
   aspect ratio correction.
