A proper copy is usually issued after it was found that there were errors in the original version. Often they
are minor and can be ignored, but if you want a proper copy, you will have to download the proper copy.
Another term you will come across is a repack. This term is often used when part of adverts are
inadvertently included in the original version or part of the story is missing, even the sound can be poor. A
repack version has eliminated these errors.
