 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.
