 Finally, the patch for this classic demo is finished too. Started way
 back in October 2011 it then stayed untouched on my HD for almost
 5 years until June 2016. I then fixed a lot of bugs and problems in almost
 any part (OCS only DDFSTRT/STOP settings, uninitialised copperlist buffers,
 ROM access and similar things) and more or less completed the patch. But
 didn't feel like creating the install package so it took another almost
 4 years to finally get that fixed as well. I also added support for the
 bootblock intro on disk 2 as well which meant I had to recode the scroller
 as it was done using graphics.library routines (ScrollRaster, Move, etc.)
 and also code a small routine to generate the data for the starfield as
 it was taken from the ROM in the original intro.

 Creating this patch was a lot of work but the demo fully deserved it!
 Enjoy this classic from HD.


 Stay safe and healthy everyone,
