A command-line tool to recalculate the EDC/ECC fields of a Playstation game image that is in 2352 byte (RAW) sector format. Should work for almost all images that include audio tracks, but will always notify such a case with a warning.

Based on Neill Corlett’s EDC/ECC code from his cmdpack utility suite. Can be compiled from the C source with GCC.

Usage:

error_recalc imagename.bin 1

imagename.bin will be modified accordingly.

The optional second argument can be set to 0 in order to zerofill mode2form2 sector EDCs, as they may be optional. If omitted, it is treated as 1.
