NAME

cdpatch - CD-XA image insert/extract utility

SYNOPSIS

Insertion

cdpatch -i imagefile [-be|-boot|-d dir|-f|-le|-o|-r|-v]

Extraction

cdpatch -x imagefile [-be|-boot|-d dir|-f|-le|-o|-r|-v]

DESCRIPTION

Inserts or extracts files in-place into CD-ROM images in either .BIN or .ISO format. Properly handles CD-XA streams from Mode 2 CDs (video CDs, PlayStation CDs, etc) and patches EDC/ECC data as appropriate.

By default, cdpatch will attempt to insert or extract every file in the CD image, the same as if you’d specified -r .. The -boot option will insert or extract the 32KiB boot sector to a file named boot.

Some CD images may have conflicting sets big- and little-endian metadata as a platform-specific quirk or copy protection scheme; the -be and -le options can be used to override this.

Specifying both -f and -v will list all file system errors, while still ignoring them for extraction purposes.

When extracting files with -x, cdpatch preserves file modification times when possible.
