Describe the issue

As of this pull request ZSO support was implemented.
However, it does not work for me.

It states the following error:

<path to ZSO>: bad ISOFS.

with a return code of 111.

I'm also unsure what the point or purpose of this other pull request is.
Why require the .ISO to be next to it? That's completely backwards to the point of compressing these in the first place.

You're argument about 'Extract the ZSO to ISO first' in this comment doesn't sit right with me. Have hdl-dump do that if it's strictly necessary. It's not as simple as "extract" for most people's setups requiring to instead use something like OPL Manager to do so which is incredibly repetitive. And at that point, why is it necessary at all?

P.S., I did in fact have the original ISO next to the ZSO under the same filename during this call.

The full call command line is, ['.\\hdl_dump.EXE', 'cdvd_info2', 'H:\\007 - Agent Under Fire (Europe) (En,Fr,De,Es,Nl,Sv).zso']. The same happens under cdvd_info and cdvd_info2, which I'm unsure of why two commands exist.

Console model

doesnt matter
