Usage: Open your savefile, for example MemoryCardA.raw in a hex editor and update the gamecode and makercode according to yagcd 12.3.1 for the game you want to fix. And remember to update the tag on both locations, both Directory and Directory backup as explained in yagcd. Then open the file, still MemoryCardA.raw or whatever it's called in the Memcard manager (found under the Misc menu). That should correct the checksums. You don't need to do anything else after that, don't click Copy for example. Just close the Memcard manager and use the savefile in the latest revision.
