Guess what I did this morning when I arrived at work. :) I remembered
this old demo from Norway and created a patch for it. Not that many
parts but they are all still enjoyable. I can't say the same about
the code though, it is rather chaotic "spaghetti code" which really
isn't nice to look at! But at least there were not many bugs that had
to be fixed. The replayers had the usual bugs, after part 4 there only
was trash on screen on machines without Kickstart 1.2 due to a "lazy
approach" to restore the copperlist (fixed address was used to set
copperlist), some timing bugs had to fixed as well and there were some
other minor things which had to be patched.
All parts were crunched with ByteKiller, I have relocated all decrunchers
and added an error check, if decrunching fails WHDLoad will quit with an
appropriate error message. I have also added ButtonWait support for the
loader screen, if enabled the next part will not be started until the
right mouse button has been pressed.

Enjoy the demo from HD.
