What it is

bchunk is a free command-line utility that converts CD images and tracks. It accepts a .bin image, a .cue index containing track types and offsets, and an output basename. BIN/CUE and RAW/CUE inputs can produce ISO or CDR output. The -w option writes audio tracks as WAV files, while -s changes the byte order of audio samples. For MODE2/2352 tracks, -p handles PlayStation mode by outputting 2336 bytes from offset 0; -r writes raw 2352-byte data from offset 0. The README identifies the program as binchunker version 1.2.2 and describes compiling with make and installing with make install. Its changelog records fixes for a heap-based buffer overflow and a null access violation and crash caused by malformed CUE files. bchunk runs on Linux and macOS, is released under the GNU GPL version 2 or later, and has no GitHub releases listed.
