Here it finally is, the patch for the first ever Amiga Megademo from Finland.
It was requested by Karpow back in 2009 already and I started to work on
the patch in July 2009. I had all parts patched after 1 day but there were
a few problems and I somehow more or less forgot about this patch and patched
a lot of other demos and games meanwhile. I always wanted to finish this
patch as I really like the demo but somehow never got around to doing it.
Yesterday, after I came back from the cinema (watched Fast & The Furious 6
with the better half) I suddenly had the idea to finish this patch, isn't
life strange sometimes? :) In the end this meant that I actually redid
most of the patch as I converted it to use real files now. I also fixed
an access fault in part 3 (disk mag), added 68000 quit key support and
also added an option to skip the rather long intro parts. To skip the
intro parts you can use the CUSTOM1 tooltype, following options are
CUSTOM1=1: skips the first intro (intro text and explostion animation)
CUSTOM1=2: skip the countdown that appears before the demo starts
CUSTOM1=3: skips both intro parts
I also had to add blitter waits as there were almost none in the demo.
The coder used the blitter nasty setting to avoid waiting for the blitter
but this only works on 68000 machines. The blitter waits are only added
on machines with a 68010+ CPU to avoid slow downs. You can force them on
68000 machines with CUSTOM2=1.
Well, I guess that about wraps it up, enjoy this very nice demo from HD!
Special greetings to Karpow, sorry that you had to wait so long but now
it is finally done! :)
Well, quite a big update this one, I have fixed quite a few problems.
Demo could freeze after the first part on fast machines, this has
now been fixed. I have also fixed a lot of copperlist problems and
the annoying graphics trash that appeared when the intros were skipped
is now gone as well. There also was the problem that the last frame
of the animation was shown while loading the next intro part, this has
now been fixed as well. Then there were problems with the scroller in
the greetings part, these were caused by a wrong blitter wait, on
slow machines this had no effect as the blitter was already finished
when reaching this part, on fast machines things were completely
different though. Took me quite a while to find this problem but it
now is fixed too.
The end part tune was replayed too slow on machines with slow chip
ram access, I have fixed this by adding a vertical blank interrupt
which is now used to replay the tune.
I have now also added ButtonWait support for those of you who want
to listen to the loader tune.
Thanks to Frequent/Ephidrena for testing.
