The documentation points out why this is happening....

"Other" Rommanagers and Ziputilites don't do a full zipintegrity test. Winzip, for example, only unzips the files to memory, calculates the crc32 and compares this checksum with the one in the zipstructures if you do a "test" operation.

ClrMamePro tests zipdata and zipstructures. Your zipdata can be 100% ok while the zipstructures are bad. Bad zipstructures can cause major problems when you add or remove files from such a bad zipfile.

That's why ClrMamePro complains about them. It's a real pain if you see how many bad zipfiles are out there.

Solution: Rezip them. Unzip the files, delete the archive, rezip the files to a new archive.
