ecm-uncompress1

Usage

Overview

ecm-uncompress is used to recreate CD image files (ISO, BIN, CDI, NRG, CCD or any other format that uses raw sectors) from ECM files, by regenerating Error Correction Codes (EEC) and Error Detection Codes (EDC) striped by the program ecm-compress.

Because ecm-compress only discards EDC/ECC data for sectors where it's verifiably possible to recreate that data, the process is lossless.

Examples

ecm-uncompress foo.bin.ecm

regenerate the ECC/EDC data from foo.bin.ecm and save the resulting CD image as foo.bin

ecm-uncompress foo.img.ecm foobar

regenerate the ECC/EDC data from foo.img.ecm and save the resulting CD image as foobar
