Works fine on my A3000 under 2.04!  I have no idea what your problem is.  What
computer are you using?  Maybe try another disk (i.e. that one might be bad)?..

Oh my god... FOund an old Lords dude... Cool... I ran a board a while 
back, that used to distribute the demos from Venom, and thats how I got
yer demos (wasn't Lords an off break of Venom??)... It'd be cool if you
guys got back together on the Amiga... I'm just starting to get into 
Asm, maybe I could start a little something in the US... Hmmm.. 
I haven;t actually seen any demos from the US for the Amiga... Anyone
wanna try and get a group togther, cause I'm sure there's alot of people
getting tired of switching to PAL everytime to see a demo! Heh heh...
AH well... Just a thought.... 

Oh yeah, Rerveb, what was yer last guys demo? The last one I snagged was
Dreams I think (or something like that..)... Still have it somewhere...

how about a demo for a workstation?  I mean, with $15000 worth of computer

Has there ever been a demo coded in any other langauage?? Cause I wanna 
come up with a demo, but I don't know Assembly, nor do I have the time to 
learn.. I do know C quite well, and actaully got some decent speed out of
a couple vector (just lines though..Haven't tried prging the Blitter
yet...) boxes... 

Now.. I could use an algorithum for a Plasma... I would love to do one,
but can't quite figure it out yet... Maybe an example algurithim (and
a spelling checker?).. 

Also... What systems has HardWired worked on? Anyone get it working yet?
Will it work on a: A2000, 1M Chip, 2M Fast, 2 Floppies?

Ah well... Thats it fer nows......

Using sprites is the fastest and easiest way to do it.
For example, make a sprite which goes like this:

sprite0:
 dc.w $30aa,$3100      ;start at y-pos $30
 dc.w $8000,$0000      ; first star
 dc.w $32bb,$3300
 dc.w $8000,$0000	;second star
 dc.w $34cc,$3500
 .
 .
 .

(I'm not really sure that the second control word should contain the y
position +1, making a sprite one pixel high, you'll have to check that.)

The values aa, bb and cc should be some random byte values (so the stars
start at different x-positions). The code for moving them look like this:

movestars:
	lea sprite0(pc),a0

	addq.b #a,1(a0)
	addq.b #b,9(a0)
	addq.b #c,17(a0)
	.
	.
	.

...and a, b and c should be some small random values. This way to do it takes
quite much memory, you can of course change the movestars routine to make a
loop and reading the star speeds from a list, but that is slower. Anyway, a
few hundred bytes can be sacrified for the sake of speed.

Good luck, hope you can do it, as more american demos would be fun...

That doesn't matter, as a demo is good only for a few months (well, up to
a year sometimes), then there are newer and better demos. There are some
exceptions, "Classic" demos which never goes out of style.

Just writing programs in C doesn't make them portable to newer
machines. C programmers can do the very same mistakes as assembler
programmers. The only difference in portability between C and assembler is
that C programs sometimes can be ported to a machine with a different
processor, but since we're talking Amiga, that's off subject.

That is mostly true... however, I personally like a demo to work years

    Honestly, I don't know of any animation format that runs on almost
    any platform. And of the few animation formats I've seen or heard
    about, the playback routines are usually in assembler (except when
    they are in hardware :).

    Well, Imagine is pretty amazing. Hell, even Excel is quite
    amazing. It's a different kind of amazing to demos, though.

    It's like the difference between plasma and what the PCs seem to
    call plasma. The latter is a cheap effect, the former is very
    slick.

It _IS_ a joke... It was great fun at The Party '91 where it was released.
Imagine the competition where 1200 freaks watched all the demos on the big
screen and then an ANARCHY demo crashed!!! Everybody laughed their buts off
but ANARCHY got the last laugh (which is the best as you know). Great joke.

Well, no, I've never heard about the man, and I've never seen any of
his hacks (all my Amiga-heroes are european coders...) and around here
he isn't the counted as the "original Amiga hacker".
 I assumed that he was a beginner who wanted to learn how to code
(since he didn't seem to know anything about demo-coding) and tried to
give a few hints. I appologize if I was sounding too simple.

I have thought that this would be an excellent idea for a long time.
Some groups do attempt to switch to PAL automatically, for instance...
but the shame is that most do not.  And, much as I hate to do it, I
really won't hesitate to use SwitchInstall on someone's demo if it's
possible.

	I suppose I'll hardly be alone in responding to this...

	Copper is a very rough abbreviation of CO-PRocessor.  It's a very simple
processor with three different instructions:
	WAIT for a bit-masked video beam position (accurate to 4 lo-res pixels,
I think) e.g. wait for line 56, or wait for pos. (100,100), or even wait 'til the vertical
beam's position value ends xx100
	MOVE an immediate data value into any chip register
	SKIP the next instruction if the video beam position is beyond the position
specified in this command.

	By using SKIP followed by MOVE 0, COPJMP2 you can do loops.

	By the by, the blitter isn't just a display DMA handler, it's a general data
manipulator.  Three sources and one output of rectangular areaas of memory, shifts,
masks, and minterm logical functions.  It'll also perform fill operations as it's copying
data, or can draw lines.
	Rectangular memory means you define the size of the block, and the width
of the bigger block it's in:
	x x x x x x x x x x x x x x
	x x X X X X x x x x x x x
	x x X X X X x x x x x x x
	x x X X X X x x x x x x x
	x x x x x x x x x x x x x x

	Is a 4x3 block, address (Base+16), modulo 10.
	At the end of each line, the blitter adds the modulo value onto the address,
thus moving to the next line.  The bitplane DMA is done in the same way, allowing a
huge playfield, with only a small section visible.  Scrolling in O(1) time!

Well, glad that people still like it. I hope you have uploaded the version
working on 1.3 - the version which work on 1.2 only is the one that is

Actually, there used to be a lot of "demos" competition in the States also.
I remember a lot of "Dr. Gandalf's" animations... (among other things).  
Too bad not many Americans care about the Amiga enough to have these
kinds of competitions anymore... :(
