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!
The demo can be downloaded here:
Have a nice weekend everyone, more patches will follow soon.
