NetHack 3.7 for Amiga
====================
Requirements
------------
- AmigaOS 3.0 or later (Kickstart 39+)
- 6 MB free RAM minimum (8 MB recommended)
- Hard drive with ~5 MB free space
Recommended: RTG graphics card (Picasso96/CyberGraphX) for best
tile rendering. Native AGA/OCS/ECS chipsets are supported.
Installation
------------
Extract NH370AMI.ZIP to a directory and assign it:
assign NetHack: <path>
The directory should contain:
nethack - game binary
nhdat - data library
symbols - symbol set definitions
sysconf - system configuration
nethack.cnf - game options
hack.font - font descriptor
hack/8 - font bitmap (8pt)
tiles/tiles16.iff - 16-color tiles (OCS/ECS)
tiles/tiles32.iff - 32-color tiles (AGA/RTG)
tomb.iff - tombstone image
record - high score file
To play:
cd NetHack:
nethack
Display Modes
-------------
Two display modes are available, selected in nethack.cnf:
Text mode (AMII):
OPTIONS=symset:AmigaFont
Tile mode (AMIV):
OPTIONS=windowtype:amiv
Tile mode auto-selects tiles32.iff (32 colors, 5 bitplanes) when the
screen supports 32+ colors, otherwise tiles16.iff (16 colors, 4 planes).
Configuration
-------------
Edit nethack.cnf for game options. Key settings:
OPTIONS=windowtype:amiv - tile graphics (default)
OPTIONS=symset:AmigaFont - text mode with line-drawing chars
OPTIONS=menucolors - colored inventory items
OPTIONS=time,lit_corridor - show turn count, lit corridors
OPTIONS=boulder:0 - display boulders as '0'
Menu color examples (add after OPTIONS=menucolors):
MENUCOLOR=" blessed "=green
MENUCOLOR=" cursed "=red
MENUCOLOR=" uncursed "=cyan
Building from Source
--------------------
Cross-compilation from Linux using bebbo's m68k-amigaos-gcc toolchain
(https://franke.ms/git/bebbo/amiga-gcc):
# Install toolchain to /opt/amiga
# Clone NetHack 3.7 source
cd NetHack
sys/unix/setup.sh sys/unix/hints/linux.370
make fetch-lua
make CROSS_TO_AMIGA=1 fetch-regex
make CROSS_TO_AMIGA=1 all
make CROSS_TO_AMIGA=1 package
The distribution ZIP is created at targets/amiga/NH370AMI.ZIP.
Toolchain requirements:
- m68k-amigaos-gcc (bebbo's amigaos-cross-toolchain in /opt/amiga)
- -noixemul (libnix) for linking
- -m68000 for maximum compatibility (or -m68020/040/060)
Known Issues
------------
- Native Amiga compilation (SAS/C, DICE) is not supported;
cross-compilation with GCC is required

Richard Addison, Andrew Church, Jochen Erwied, Mark Gooderum,
Ken Lorber, Greg Olson, Mike Passaretti, and Gregg Wonderly
polished and extended the 3.0 and 3.1 ports. Andrew Church,
Ken Lorber, and Gregg Wonderly are responsible for the 3.2 port.
Janne Salmijärvi resurrected the Amiga port for 3.3 and
Teemu Suikki joined before 3.4.0.
Updated for NetHack 3.7, cross compile fixes and 32 color tile support by Ingo
