UNECM(1)
NAME
unecm - regenerate error correction codes from ECM files
SYNOPSIS
unecm ecmfile [outputfile]
DESCRIPTION
unecm 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.
Because ecm only discards EDC/ECC data for sectors where it's verifiably possible to recreate that data, the process is lossless.
EXAMPLES
- unecm foo.bin.ecm
- regenerate the ECC/EDC data from foo.bin.ecm and save the resulting CD image as foo.bin
- unecm foo.img.ecm foobar
- regenerate the ECC/EDC data from foo.img.ecm and save the resulting CD image as foobar
