This patch was requested a few years ago and now it's finally finished.
The demo uses quite a few graphics.library routines which took me quite
some time to properly emulate. When I patched Bronx Megademo2 a few days
ago I had a look at the patch for Gigademo 3 again, added the missing graphics
library emulation routines and finally finished it.
There were no special problems to fix except for a wrong DDFSTOP value in part 3
which caused the scrolling logo to be messed up on anything else than OCS machines.
There also were nice bugs in the line drawing routines in this part, registers
were used as .l without properly initialising them before.
Other than that there were just the usual problems such as CPU dependent delays,
buggy DMA waits in the replayers and stuff like that to fix.
All parts were crunched with ByteKiller, I have relocated all decrunchers
as usual and added an error check, WHDLoad will quit with an appropriate
error message if decrunching fails.
The demo doesn't feature the most advanced code, a lot of grammar and spelling
mistake but is still quite entertaining to watch. And "mod.echoing" by Banana
used in the loader part is a timeless classic which will still sound great in
Enjoy the demo from HD.
