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.
