Step22: HAWK Mega demo – August 1990
Johnny-B and I worked almost during one year to create this production. We acheived something huge for us: A complete mega demo. A «mega demo» is a collection of chained demos. In this case the exact name is «Trackmo». That means the demos are launched directly from the tracks of the floppy disks.
The demo is divided into 4 parts, with intermediates parts (executed while loading and uncrunching demos, these are called «loaders»).
The name of that production is : «Flight over Fight».
The amiga disk can be found here:
Hawk_1990_Megademo_FlightOverFlight_1MoVersion.adf
1Mb of memory required to run this demo. See folowing link for 512Kb version.
Hawk_1990_MegaDemo_512KoVersion.adf
Here is the full demo video:
Sadly the WinUAE emulator is not perfect. The winter demo is not emulated very well. Here is a video on a real Amiga 500.
The full source and data are here: Demo_HawkMegaDemo.zip
Part 1
First part isterminator based on «Terminator» movie. We reproduced the opening title sequence.
Arts
The big letters are drawn using small parts of 16×16. You can see after the decomposition of the «tiles» and one result letter.
the «tiles»
Sample of a letter
I remember that we checked the video on philippe VCR. There was no internet and no DVD at that time 🙂
The color gradient is done via the copper list.
Source code
Here is the source code: PartI.s
There is a nice header in this one:

In a general way, I wrote better source code. I added some separators and the code is cleaner that my first demo.

Musics
Johnny B reprocuded the Terminator music. You can get the module HERE. 128 Ko. I like this one.
Part 2
Second part featured a remix of Prince BatDance.
Here is the original video clip:
Arts
The batman logo done by Johnney-B is really great.

Source code is here: PartII.S
I remember working on the rasters animation while beeing in holidays at my grandma house. It took me some time to get the correct motion. (a «raster» is usually moving colored horizontal bars). Ther bars are going backward in a kind of «3D» effect. As I had no idea of how to do «3D», this is big tricks.
The music replay routine have been changed to detect when the note are played and flashes the two logos. Variables of replay routine are directly used (named «MT_***»).The code for this is:
EQUA:
ADD.W #1,MT_COUNTER1
CMP.W #6,MT_COUNTER1
BNE.S FINFINFIN
CLR.W MT_COUNTER1
LEA MT_VOICE2(PC),A0
MOVE.W 2(A0),D0
AND.W #$0F00,D0
CMP.W #$0A00,D0
BEQ RAST_UP1
SUITE_EQUA:
LEA MT_VOICE1(PC),A0
MOVE.W 2(A0),D0
AND.W #$0F00,D0
CMP.W #$0A00,D0
BEQ RAST_UP2
Music
The music is also nice. He sampled parts of the batdance and recreate the song under soundtracker in only 368 kb !. Download the module HERE.
Part 3
«Shadow-of-the-beast» like scrolling. The musics and graphs were still very good.
Arts
The arts may be inspired from Unreal video game. The trees looks the same as in Unreal (but Johnny B redrawn them from screenshots I guess. There are not the same). You can see lot of great artworks from that game on the Frank Sauer page
Source code
Source code is here: PartIII.s
To create scrolling on Amiga it was very simple. You only have to use the video pointer and change the value (video pointer is 16 pixels accurate, decay register is 0 to 16 pixels. Using both, you can create a one pixel scrolling). Using video pointers is free for the main cpu. The whole scrollings in the winter demo is using no CPU at all. The video pointers are inside the copper list, which is very easy for synchronisation with the display.
This source code is the longuest I’d ever wrote. It is about 96Kb. The copper list is big because of all parallax scrolling.
At the beginning, you can see some snowflakes falling down. The farer small disappear when going behind the trees.
The logo at the end, is displayed using the «Extra half bright» mode. This special mode required a 6 bitplane to be setup. The total color is 64 (32 colors, and 32 others colors that are «half bright» of the first 32 colors). The amiga hardware have a limitation of 32 color register. This mode allow 64 colors to be displayed. You can see it in the demo with the «Hawk / Amazing world of creation» bouncing logo.
In the source code, you can also see the usage of a macro:
ET:MACRO ; Definition of «ET» macro
DC.W ?1,?2,1,1,?3,0,?4,0,178,?5
DC.L ?6
ENDM
ET 110,-210,4,1,-3,BOB1 ; Use ET macro.

Music
The music is a nice slow theme, using a pan flute, like «Shadow of the beast» (but that sounds was used a lot at that time., like the great Hans Zimmer theme of the movie «Rain Man»).
The module can be found here : stormy-monday
.mod (186 Kb)
Rain Main theme:
Part 4
This is end part.
Music might be «never ending story» by Demon aka Allister Brimble.
The end picture audio was taken from the game «Manoir de Mortevielle» from Lankhor. I’m sure the die hard fans recognized it.
Loaders
In that mega demo I coded a whole system of «loaders». When loading the demos, there were animation with texte and musics. The track loading was done in background as well as the uncompression of the demos. That was a real hard work. Amiga system was a real multitask machine. At that time, that was very rare for computers.
Loader 1
That first simple loader mention a genesis song, named "Land of confusion".
Arts
Musics
«NEWDIMENSION» by Zzzax / Time Circle.
Source Code
You can read source code here: LOADERI.S
Loader 2
Second loader. This one use a nice trick to inscrease the numbersof displayed colors. It displays two gradients, in an interlace way. It doubles the number of colors (check in the video, can not be seen on a screenshot like below).
Arts
Musics
«ZZZAX NO EG» by Zzzax / Time Circle.
Source Code

Loader 3

Musics
«EXPRESSION» by Zzzax / Time Circle.
Music is a cover of «Street hawk» serie music. Original music by Tangerine Dream.

New members
In the loader source code, I can see the «Skywalker» helped me for the loaders. I guess we sent some papers mails. He was coding some intros for Paradox at the time.
Hidden messages
Displaying the disk binary made some messages appear. We surely wrote some data in unused space of the floppy disk.
Here are the messages:
"THIS IS A NEW HAWK PRODUCTION. 1 MEGA WORKING VERSION … REMEMBER: RIP IS LAME !!!!!!!!! —————– HAWK —————–MEGA DEMO I FINISHED : 22 / 08 / 90 AT 2:05 AM LET’S GO TO BED -ORIENS -JOHNNY-B -KREATOR WISH YOU A GOOD TIME WITH THIS PRODUCTION. WAIT FOR OUR FUTURE CREATION. RIP IS LAME !!! 3614 RTEL1 BAL ORIENS TO CONTACT US."
We mention rip which is the action of extracting art or music from a production and reuse it. The funny part of that is that the loader musics are not from us, and we ripped audio sample from a game for Part 4!!!
Disks
Disks of the 512Kb version
To save the source code of all that works I used the most beautiful disks I had. Here they are:
I also stored all data on 5 1/4 disks: (I had two 5 1/4 drives on my Amiga)
Great games of that time
Shadow of the beast : This is an incredible released in November 1989. That game inspired our «winter demo» (part 3) (for the graphic parallax and the music style with pan flute).
Here is «shadow of the beast» game:
That game was really impressive. It fully used the A500 and copper capacity. The different speed scrolling gave depth effect (this is called «parallax»).
You can have read technical detail on codetapper website: HERE.
Batman the movie: We played that game while developping our Batman demo. The race parts were really nice. As I was working a lot at Johnny-B’s place, I brought there my A500. I remember that we were playing the batman race part with two amiga. No link between amiga, but it was like we were racing in LAN! Great memories.
Great demos of that time
