Create bootable Amiga ADF disk images from executables.

This tool creates ADF (Amiga Disk File) images that boot and run a specified executable, compatible with AmigaDOS 1.2+ using the OFS (Old File System).

It was inspired by exe2adf (https://exe2adf.com/), but since that tool has no source code available, this tool was made.

Based on documentation from http://lclevy.free.fr/adflib/adf_info.html

• Creates bootable 880KB DD floppy disk images
• Cross-platform (Windows, Linux, macOS)
• Compatible with AmigaDOS 1.2+ (OFS filesystem)

cd src
go build -o gadf ./cmd/gadf

Or install directly:

go install github.com/sphair/gadf/cmd/gadf@latest

# Basic usage - creates demo.adf that boots and runs demo.exe
gadf -i demo.exe

# Custom output filename
gadf -i demo.exe -a mydisk.adf

# Custom volume label
gadf -i demo.exe -l "My Demo"

# Include additional files and directories (preserves structure)
gadf -i demo.exe data/ music/

# Include directory but flatten all files to root
gadf -i demo.exe -f data/

# Mix files and directories
gadf -i demo.exe readme.txt data/ music/

# Suppress shell window on boot
gadf -i demo.exe -s

-i <file>    Input executable (required)
-a <file>    Output ADF filename (default: <input>.adf)
-l <label>   Volume label (default: input filename, max 30 chars)
-f           Flatten directory structure (put all files at root)
-s           Suppress shell window on boot
-h           Help
-version     Version info

You can specify multiple files and directories as arguments after the flags. Directories are always processed recursively. Use -f to flatten the structure.

By default, uses a minimal bootblock that works on all Kickstart versions (1.2+).

The -s flag adds expansion.library code to suppress the shell window flash on KS 2.0+. This option works with KS 1.2+ (the disk will boot), it just won't suppress the shell window on older Kickstarts (the expansion.library call silently fails).

<volume label>:
├── <executable>           # Your executable
├── S/
│   └── startup-sequence   # Boot script that runs your executable
└── [additional files]     # Any additional files/directories specified
