Starting:
--------
The demo comes with two different
starters on disk:
"omd.full"
Shows all effects old and new...
So if you have some time left
start this one. Runtime is almost
16 minutes...
"omd.new.parts"
If you fed up with the old
effects you can run this one.
Shows only the new effects.
Except of intro and endpart.
Runtime is almost 10 minutes...
Compatiblity
------------
Does not work on 1540, 1581 and
SD2IEC (i guess). These users
have to use the old version.
Tested on real hardware and seemed
to work so far...
Note:
-----
Do you know this?
Things you always wanted to
code but you never managed?
Because of different reasons
like:
-no time
-not at the top of the prio list
-job
-or too lazy?
Back when I (ultra) was 13 fast-
and irq loaders on C64 popped up
and I was totally fascinated
of this stuff.
Till then I only did a few
intros.. And I said to myself:
One day... I will code my own
fastloader.
And just 31 years later...
I finally did it :)
In 2007 I did a 1541 emulation
on a pic32 controller just to
get into the entire theme.
So it was a logical consequence
to write an own fastloader.
The fastloader is done since
7 or 8 years but I wanted to
fastload our vc20 demo "omd"
and that was a real problem
since there isn't enough
memory left to hold the fast-
loader in memory.
So the entire project went to
sleep for some years but one
day I had the idea. Why not
download the fastloader code
from floppy memory before?...
So I did...
The download needs 28 bytes in
memory this is even smaller
than the old loader ;)
New Features:
-------------
-Fastloader: On the fly GCR
decode (can be done faster I
know was enough for the vc20)
-5 new 4mat tunes
-6 new screens
-two new effects from 4mat
-the end part has been
totally rewritten by 4mat
-three new effects from ultra
-All screens of ultra have
been reworked to fade out clean
-Some of the screens got a facelift
-Samples and replay in the
checkboard zoomer was updated.
we recognised it's almost
not hearable on real hardware.
-Fixed bugs
In two screens we are using the
unconnected ram feature first
used by viznut...
Thanks:
-------
-must go to Viznut to his waves and
unconnected ram stuff.
-Krill I borrowed his head
moving routine...I'll write
one soon ;)
