amifuse
Mount Amiga filesystem images on macOS/Linux/Windows using native AmigaOS filesystem handlers via FUSE.
amifuse runs actual Amiga filesystem drivers (like PFS3) through m68k CPU emulation, allowing you to read Amiga hard disk images without relying on reverse-engineered implementations.
Requirements
macOS: macFUSE
Linux: FUSE for Linux
Windows: WinFSP
Python 3.9+
7z: Required for make unpack (install via brew install p7zip on macOS)
A filesystem handler: e.g. pfs3aio (or use make download)
Installation
# Clone the repository with submodules
git clone --recursive https://github.com/reinauer/amifuse.git
cd amifuse
# Or if already cloned, initialize submodules
git submodule update --init
With virtual environment (recommended)
python3 -m venv .venv
source .venv/bin/activate # On Windows: .venv\Scripts\activate
pip install -e './amitools[vamos]' # Install amitools from submodule (includes machine68k)
pip install -e . # Install amifuse
Without virtual environment
pip install --user -e './amitools[vamos]'
pip install --user -e .
macOS-specific
Install macFUSE from https://osxfuse.github.io/ or via Homebrew:
brew install --cask macfuse
You may need to reboot and allow the kernel extension in System Preferences > Security & Privacy.
Linux-specific
# Debian/Ubuntu
sudo apt install fuse libfuse-dev
# Fedora
sudo dnf install fuse fuse-devel
Quick Start
To download a test PFS3 disk image and the pfs3aio handler:
make download # Downloads pfs.7z and pfs3aio to Downloads/
make unpack # Extracts pfs.hdf and copies pfs3aio to current directory
Then mount with:
# macOS: auto-mounts to /Volumes/, uses embedded driver from RDB
amifuse mount pfs.hdf
# Linux: requires explicit mountpoint
mkdir -p ./mnt
amifuse mount pfs.hdf --mountpoint ./mnt
Usage
amifuse uses subcommands for different operations:
amifuse inspect # Inspect RDB partitions
amifuse mount # Mount a filesystem
Inspecting Disk Images
View partition information and embedded filesystem drivers:
# Show partition summary
amifuse inspect /path/to/disk.hdf
# Show full partition details
amifuse inspect --full /path/to/disk.hdf
Argument
Description
image
Path to the RDB image file
--block-size
Block size in bytes (default: auto-detect or 512)
--full
Show full partition details
Mounting Filesystems
amifuse mount /path/to/disk.hdf
Argument
Required
Description
image
Yes
Path to the Amiga hard disk image file
--driver
No
Path to filesystem handler binary (default: extract from RDB if available)
--mountpoint
macOS/Windows: No, Linux: Yes
Mount location (macOS: /Volumes/, Windows: first free drive letter)
--partition
No
Partition name (e.g., DH0) or index (default: first partition)
--block-size
No
Override block size (default: auto-detect or 512)
--volname
No
Override the volume name shown in Finder
--debug
No
Enable debug logging of FUSE operations
--profile
No
Enable cProfile profiling and write stats to profile.txt on exit
--write
No
Enable read-write mode (experimental, use with caution)
--icons
No
Convert Amiga .info icons to native icons (experimental, macOS only)
Examples
# macOS: Mount using embedded filesystem driver from RDB (simplest)
amifuse mount disk.hdf
# macOS: Mount with explicit driver
amifuse mount pfs.hdf --driver pfs3aio
# Mount a specific partition by name
amifuse mount multi-partition.hdf --partition DH0
# Mount a specific partition by index
amifuse mount multi-partition.hdf --partition 2
# Linux: Explicit mountpoint required
mkdir -p ./mnt
amifuse mount disk.hdf --mountpoint ./mnt
# Mount an ADF floppy image (requires explicit driver)
amifuse mount workbench.adf --driver L/FastFileSystem
# Enable native icons (macOS only, converts Amiga .info files)
amifuse mount disk.hdf --icons
# Browse the filesystem
ls /Volumes/PDH0 # macOS
ls ./mnt # Linux
# Unmount when done (Ctrl+C in the terminal, or:)
umount /Volumes/PDH0 # macOS
umount ./mnt # Linux
Additional Tools
rdb-inspect
Inspect RDB (Rigid Disk Block) images to view partition information and embedded filesystem drivers.
# Show partition summary
rdb-inspect /path/to/disk.hdf
# Show full partition details
rdb-inspect --full /path/to/disk.hdf
# Output as JSON
rdb-inspect --json /path/to/disk.hdf
# Extract embedded filesystem driver #0 to a file
rdb-inspect --extract-fs 0 --out pfs3.bin /path/to/disk.hdf
Argument
Description
image
Path to the RDB image file
--block-size
Block size in bytes (default: auto-detect or 512)
--full
Show full partition details
--json
Output parsed RDB as JSON
--extract-fs N
Extract filesystem entry N (0-based) to a file
--out
Output path for extracted filesystem (default: auto-derived)
driver-info
Inspect Amiga filesystem handler binaries to verify they can be relocated and display segment information.
# Inspect a filesystem handler
driver-info pfs3aio
# Use a custom base address
driver-info --base 0x200000 pfs3aio
Argument
Description
binary
Path to the filesystem handler binary
--base
Base address for relocation (default: 0x100000)
--padding
Padding between segments when relocating
Supported Image Formats
HDF/RDB - Hard disk images with Rigid Disk Block. Filesystem drivers can be embedded in the RDB or specified via --driver.
Emu68-style MBR images - Disk images with MBR partition table containing an RDB partition, as used by Emu68 on Raspberry Pi.
ADF - Amiga Disk File floppy images (DD and HD). Requires --driver since ADFs don't contain embedded drivers.
Supported Filesystems
Currently tested with:
PFS3 (Professional File System 3) via pfs3aio handler
SFS (Smart File System 1.279) via SmartFileSystem handler
FFS/OFS (Fast/Old File System) via L:FastFileSystem from Workbench
BFFS (Berkeley Fast File System) via Chris Hooper's BFFSFilesystem handler
Other Amiga filesystem handlers may work but have not been tested. Reports are
welcome.
Icon Support
The --icons flag enables conversion of Amiga .info icon files to native Finder icons:
Folder and file icons from .info files are displayed in Finder
Supports Traditional, NewIcons, and GlowIcons formats
The .info files are hidden in directory listings
Volume icons are displayed on the Desktop
*** This feature is experimental and macOS-only. ***
Notes
The filesystem is mounted read-only by default; use --write for experimental read-write support
The mount runs in the foreground; press Ctrl+C to unmount
macOS Finder/Spotlight indexing is automatically disabled to improve performance
First directory traversal may be slow as the handler processes each path; subsequent accesses are cached
