amitools - various AmigaOS tools for other platforms


amitools is a collection of (currently python 2.x only) tools that I've written to work with Amiga OS binaries and files on Mac OS X. But they should work on all other platforms supporting Pythons, too.

I focus with my tools on classic Amiga setups, i.e. a 680x0 based system with Amiga OS 1.x - 3.x running on it. However, this is an open project, so you can provide other Amiga support, too.

The tools are mostly developer-oriented, so a background in Amiga programming will be very helpful.


  • Python 2.7.x is currently supported
  • The following Python packages are required to build/install the tools:
  • All other packages are installed automatically, if missing:
  • First make sure to have the Python package installer pip:
    • On Mac OS X using MacPorts (Tool is called pip-2.7 here):
    sudo port install py27-pip
    sudo pip-2.7 install cython
    • On Linux Ubuntu:
    sudo apt-get install python-pip
    sudo pip install cython
    • On Windows with MSYS2 (use x86_64 version if possible):
      • Install with exe installer
      • Initial update is done with: (Open shell first)
      pacman -Sy
      pacman --needed -S bash pacman msys2-runtime
      • Now close shell and re-open a new dev shell (MinGW-w64 Win64 Shell)
      pacman -Su
      pacman -S mingw-w64-x86_64-python2-pip mingw-w64-x86_64-gcc git make


  • The musashi CPU emulator required for vamos needs some code generated first:
make do_gen
  • This will create some files in directory gen
  • Now you can use Python's setuptools to install everything:
    • Global Install is available for all users of your system and needs root privileges
    sudo python install
    • User Install is available for your user only but does not require special privileges
    python install --user
    • Developer Setup only links this code into your installation and allows you to change/develop the code and test it immediately. (I prefer user install here)
    python develop --user



  • vamos V)irtual AM)iga OS

    The most ambitious project in the collection emulates the Amiga OS library API so that native m68k Amiga OS 1.x - 3.x binaries can be loaded and executed (think of Wine for Amiga :). With this approach only API conform programs can be run (i.e. no direct hardware access is possible).

    The goal is to run CLI programs relying on Exec and Dos library starting with a minimal set of implemented functions. But the design of vamos is flexible enough to add more libraries and more functions later on.

    Remember, vamos is and never will be a full Amiga system emulator like WinUAE or FS-UAE!!

    It uses the Hunk library of amitools to load and relocate the binary. A m68k CPU emulator is used to execute the code (here: Musashi emulator in native C with Python binding generated via Cython.

    Every call to a library is trapped during execution and realized with own Python code or simply ignored if no trap is defined.

    All public in memory structures (e.g. ExecBase) are also provided. vamos implements a memory handler to allocate and free structures used in the heap of a program or for library data exchange.

    Currently, this is a work in progress and mostly a proof of concept that is very instructive and even fairly fast. Its a playground for me to learn lots about Amiga OS, its binaries, its libraries and how they work together...

  • xdftool

    Create and modify ADF or HDF disk image files.

  • xdfscan

    Scan directory trees for ADF or HDF disk image files and verify the contents.

  • rdbtool

    Create or modify disk images with Rigid Disk Block (RDB)

  • romtool

    A tool to inspect, dissect, and build Amiga Kickstart ROM images to be used with emulators, run with soft kickers or burned into flash ROMs.

  • hunktool

    The hunktool uses amitools' hunk library to load a hunk-based amiga binary. Currently, its main purpose is to display the contents of the files in various formats.

    You can load hunk-based binaries, libraries, and object files. Even overlayed binary files are supporte.

  • typetool

    This little tool is a companion for vamos. It allows you to dump and get further information on the API C structure of AmigaOS used in vamos.

  • fdtool

    This tool reads the fd (function description) files Commodore supplied for all of their libraries and dumps their contents in different formats including a code structure used in vamos.

    You can query functions and find their jump table offset.


  • Hunk library amitools.binfmt.hunk

    This library allows to read Amiga OS loadSeg()able binaries and represent them in a python structure. You could query all items found there, retrieve the code, data, and bss segments and even relocate them to target addresses

  • ELF library amitools.binfmt.elf

    This library allows to read a subset of the ELF format mainly used in AROS m68k.

  • .fd File Parser amitools.fd

    Parse function descriptions shipped by Commodore to describe the Amiga APIs

  • OFS and FFS File System Tools amitools.fs

    Create or modify Amiga's OFS and FFS file system structures

  • File Scanners amitools.scan

    I've written some scanners that walk through file trees and retrieve the file data for further processing. I support file trees on the file system, in lha archives or in adf/hdf disk images
