the current problem is only the executable - we have either the fully patched exe that does not have GOG's music fix (will not play music), or the unpatched exe that has the music fix (plays music, but has bugs).
the music fix needs to be copied to the updated exe - probably by hexediting. I would do it myself, but I have no idea what they changed and where, so I'm pretty much screwed.
apart from the exe, the full patch has been ready for download for a long time (see my previous posts).
it's possible that I might find the edits when I get some more experience in hexediting - I think if I could create a dif when comparing the unpatched orig exe and GOG exe, and move that dif to the patched one, the problem would be solved.
and as much as I don't like to say this, GOG support has been all talk and no walk on this, promising a fix via support ages ago.. I understand Incubation is not really a top priority, but anyway, all that is required is that tiny little fix to the exe.
to make it short; this is the original, unpatched exe
(v1.50). this is the same exe with the GOG fix
(v1.50). this is the original, patched exe
(v1.52). the GOG fix needs to be copied over from exe no2 into exe no3 (creating a fully patched 1.52 exe with
the GOG fix).
