About:
bchunk is a command-line utility that converts CD-ROM images, typically consisting of a .bin binary track and a .cue cue sheet, into standard ISO 9660 or CDRW-compatible images. It effectively parses the cue file to correctly handle track boundaries and metadata, ensuring the resulting ISO is a faithful representation of the original disc. This tool is essential for making legacy or proprietary disc images compatible with modern operating systems and virtualization software.

Key Features:

Converts .bin/.cue pairs to standard .iso files
Supports output to .cdr format for Mac OS compatibility
Handles multi-track CD images correctly via cue sheet parsing
Command-line interface for easy scripting and automation

Use Cases:

Converting legacy game or software CD images for use in emulators
Extracting data tracks from disc images for analysis or mounting
Preparing CD images for burning to physical media on modern systems

Alternatives:

ccd2iso – Converts CloneCD images (.ccd/.img) to ISO, whereas bchunk handles .bin/.cue.
iat – ISO9660 Analyzer and Tool, aims to unify multiple image formats, but bchunk is more specialized for bin/cue.
