The one to be "blamed" that I created this patch is Noname/Haujobb, he commented
this classic on Pouet recently which made me remember this nice demo and so
I immediately started working on the patch. It still is a very enjoyable demo so
many years later and it sure deserved to be patched! :)
The code is quite good for 1989 but creating the patch still took about 6 hours
as 8 main parts, the loader and the title part had to be fixed. Except for some
blitter bugs in one part no real major bugs had to be fixed though.
The loader part flashes the upper part of the screen if the current part has been
loaded and is ready to start, press left mouse button then to start the next part.
The title picture used a CPU dependent delay so it was shown for a very short time only
on fast machines, I have fixed this of course, the title picture will now be shown
for 3 seconds. If you are very impatient you can press the right mouse button to skip
directly to the loader part.
Enough words, enjoy this great classic from HD!
