I've actually noticed with the ones I've found a download link for, when I try to extract it, I get an error regarding the FILE_ID.DIZ file. So if something's wrong with that, that could be why...?

Apogee used PKZIP's authenticity verification in their ZIP archives, which is a great help in identifying the files that come directly from them. However, this feature is known to not be fully supported with some modern third-party unzipping tools, and some of the extracted files may have odd system markings or not extract properly at all.

You can use DOS PKUNZIP to extract the ZIP contents, also I think Info-ZIP UnZip handles these files well too.

I see. Thanks. Also, that’s great there’s an unzipping tool for DOS. Super useful. 😄
