Overview:

Amiga port based on ZDOOM v1.22.

ZDoom is a source port, originally based on ATB Doom and NTDOOM. 
It has since added full support for all commonly-used Boom additions, Heretic, Hexen, Strife and Chex Quest. 
It has added many additional features, including slopes, uncapped framerate, and z-clipping.
The large number of features supported by ZDoom made it the port of choice for several independent game projects,
notably Foreverhood, Action Doom 2: Urban Brawl, Chex Quest 3 and Harmony.


Features:

1) An awesome icon!
2) SDL Mixer music support (MIDI/OGG/WAV)
3) Native MIDI support (CAMD)
4) International keyboard mapping
5) Mouse scroll wheel support for weapons switching
6) ZDOOM TC support
7) Jumping
8) Mouse Look up/down
9) A Console
10) Particle Effects (blood, rocket trails)
11) Custom Skins support
12) Gun Sights
13) A Chase Cam
14) Rotating Overlay Map


Requirements:

1) An AGA Amiga.
2) 68060 processor or better.
4) AHI installed and configured.
5) 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).


There are a few Tooltypes to play with:

displaytype: PAL, NTSC.

When running from the Shell you must specify a stack of at least 300,000
Please see the ZDOOM documentation for command line and Tooltype options.
Any errors *should* be written to a file called 'ERROR.TXT' in the game directory.


Limitations:

1) No network or multiplayer support.
2) No Joystick support.
3) Only the original MUS music format is supported.
4) Only the original 8 bit PCM Audio is supported.
5) No botty support.


Version History:

1.22.01 - Added support to run from the Shell, updated SFX and music playback.
1.22.02 - Fixed memory corruption on startup, fixed console background.
1.22.03 - Fixed console memory corruption issue.
1.22.04 - Fixed background resize issue.
1.22.06 - Updated memory allocation routines based on ODAMEX.
1.22.08 - Fixed bug with memory allocation when running with less than 128 MB.
1.22.09 - Fixed a bug with the doomsound.library.
1.22.10 - Fixed more endian issues, increased WAD support, fixed sound channel bug.
1.22.11 - Fixed memory allocation on startup (again!)
1.22.12 - Updated custom WAD file handling.
1.22.15 - Built off the latest RTG code base.


Performance Considerations:

1) Fast File System is actually not, use PFS3 instead.
2) Playing compressed audio or video on a real 68k CPU will be very slow.
3) Use v4.18 of AHI as the later versions are too slow.
4) If you are using Paula try the 'FAST' audio AHI modes.
