This should work, but may not. It's not the preferred way to do this (see
below).

This will not work correctly.

Ok. It's pretty straightforward - both for the latter case, where this is
neccesary, and for the from-memory case (where it's preferred). Rather than
using ov_open, use ov_open_callbacks, and implement a set of callbacks that
work for your format (where 'format' might be a large memory buffer, or
it
might be a subset of a single file (your resource file).
The callbacks are documented and very straightforward, but if you can't
figure
them out feel free to ask for more specific assisstance here.
