I've written some code and used the hex editor. All I get
is a few random numbers and symbols on the first few
lines then loads and loads of zeros. Is this what I
should expect or have I done something wrong? Here is the
procedure I've written.


It sounds like the zeroes are padding to make up the
required dataset length, the odds are the developers
used their own algorithms to store the data.

You need either solid data about the format or
some reference output to compare the dataset
with.
