When some of us become proud owners of CopyNESs and start dumping games, how will we know that we got a good dump and not a bad one? I suppose that if you dumped a ROM that you were able to use in a NES recently a certain number of times and always got the same CRC32 or md5 Hash you can be assured that the dump is good. But how many times does it take? Is there an easier way to go about it?
