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

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
Paschke in 2026.
