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
