EDCRE provides a solution to update EDC/EEC data to match any patching done to a data track of a CD image. This allows PSX games with EDC Protection to be patched and hacked successfully with programs such as PS1 DemoSwap Patcher and APrip using a clever workaround turned on by default. EDCRE is not limited to EDC Protected PSX games however, just specify the -z argument to enforce all sectors to be checked and fixed with updated EDC/EEC data if needed.
