 The patch for this classic demo was requested a few days ago on EAB. Took a
 little while to do as there were quite a few problems to fix and the code
 isn't exactly great. There were a lot of copperlist problems, mainly wrong
 DDFSTRT values which only worked on OCS machines. In one part the
 DIWSTART/STOP settings were completely missing, there were writes to
 read only only registers, ECS/AGA registers were accessed by accident, the
 replayers had the usual DMA wait and volume bugs and some blitter waits were
 needed as well.

 Despite the not too great code the parts are still enjoyable and there's a
 lot to see. The demo features an "auto mode", if you don't move the helicopter
 in the main menu for 15 seconds the demo will run the parts automatically.


 Enjoy the demo from HD.
