I haven't followed all of this thread - so I may have missed something,
I don't believe the problem is anything to do with the line ".DSstore" -
that would be filtered out by the filter that excludes anything not a
ZIP file, and I don't think another filter is needed.
I think the problem is the section

That filter command should be
filter ROMlist with "*.zip"
I suspect it's currently filtering out everything, and so giving the
impression that everything stops.
