That's a very interesting problem you have. As an exclusively Delphi
programmer, I don't have anything to do with the DLLs but I do have inflate
code written in Pascal. I do not plan to publish it in its current form
since it is optimised for use in a self-extractor (Zipfusion - see website
address below) however, if you know your way around Pascal, you may find it
to be easier to work with than the DLLs.
If you think that this may be of help to you, contact me directly (but a
solution from Roger or Russell is likely to involve less work on your part
since my code cannot be integrated into ZipMaster).
