 This install requires WHDLoad and RawDIC to be in the path.

 This patch should have been finished long ago (2010) but I somehow completely
 forgot about it. Some days ago someone asked if this patch had been released
 and since it wasn't for obvious reasons I restarted the patch from scratch
 as I couldn't find my old code anywhere. It was better anyway as I now
 made the patch using real files whereas the old one used disk images.

 Still an entertaining demo even though it doesn't feature any advanced
 code. Worth to mention though is that the "filled vector graphics" part
 uses matrices to calculate the rotations, not too common back in 1989!

 The code had a lot of small problems, specially the coppperlists were
 quite buggy. I also had to emulate/recode quite a few routines which
 used graphics library functions for drawing/screen setup etc. but that
 wasn't too hard to do anyway. 

 Enough said, enjoy yet another classic demo from HD, the loader tune
 by Felix Schmidt/Suntronic is excellent!
