Actually, if you are on a Mac, you would use an shntool md5 checksum the same was you would a wholefile checksum. xACT will take the file and verify the shns for you. Or, edit the file and change shn to aiff and then save it and it will verify your aiffs for you after you convert them. And then, go convert them to flac to seed (hehe) and you can simply change the extension once again to flac and verify the flac files or simply generate the ffps for the seed and do a visual comparison of the shntool checksum and the ffps and you will see that they are the same!
