I started to patch this classic back in March 2012 already. Fixed the first
few parts and then more or less forgot about it. Restarted work on it a few
days ago, almost recoded everything and changed the patch to use real files.
Even though the code isn't that bad quite a few things had to be patched
and in the end I was quite fed up with working on the patch. Luckily
it's finished now! Specially the last part wasn't too easy to fix
as it uses lots of system routines which I all had to recode!
The "final part" mentioned in the last part doesn't exist, it doesn't matter
if you successfully complete the quiz or not, the demo will always restart.
Seems they either forgot to include it or there were other reasons
(deadline?) for the part not being present on the disk.
Enough said, enjoy this classic megademo from HD!
