• Forgot the thumb... here it is.
  
  
  I was thinking of if this copper trick could be possible (only theory..):
  
  1. Set 32 $0180 background color commands in a row with copper on each line.
  2. On that, draw 5 bitplanes of 0000111100001111 etc and make that show columns in 31 colors with 4 pixels and 4 pixel background.
  
  The copper may only allow 55 colors to be set in a row..
  But then lat the copper set the 32 $0180 and then the next 16 colors $0182, $0184, $0186 etc.
  Thats 48 colors.
  
  The last 16 colors can be set by CPU simultaneously
  move.w d0,$dff1a0
  move.w d1,$dff1a2
  etc
  
  That could give 64 colors in a row.
  And int requires fewer commands to draw a color.
  So in the end a bigger area. Mabye in 4x2 ?

• Btw:
  No matter what technique used (HAM og Copper), what if the rotation itself is done by precalculated x and y skewing, like in Turmoil by Sanity, that skews Y and X separately AND only skewing the columns (and) that moved since last frame?
  That could free cpu time for a better y resolution?

• Impressive oldschool cometition!
  Good work, all of you who try this :)
  
  Its along time I have done Amiga demos and may not do any more..
  
  But I cant resiste thinking of 'how is this done'..
  
  Is any of these attempts using the technique that Flash Production did in
  "Danish Knowhow" from 1990?
  https://www.pouet.net/prod.php?which=27125
  
  There is a copper splitter on each 4 pixels.
  It uses 5 bpl with %00001111 masks to set all different bitplane 31 colors, and then it sets 32 background colors to see between the 4 px bitplane gaps.
  That makes at least 63 colors that way.
  
  Mabye this method is used now, so then please forget my comment :)
  But if not, it could mabye give some extra possibilities? Even adding sprites?
  Sadly I am not going to try, but mabye you can (re)use that old idea?

• demo Amiga OCS/ECS MØMB by Gunnars Farvebio [web]
• THE MAKING OF
  M0MB (A1200 version)
  
  After releasing Megademo 1, I was sure it I would not make any more megademos. Just a one-timer..
  
  But short after I got the idea to make a parody of Flash Production's "Digital concert" that should be a very long James Last remix music disk, just like these.
  It should have an intro, and the the entire James Last long play mix....
  But it didnt become that actually... I only made a short James Last sample module and lost interest...
  Meantime other ideas appeared.
  It became a megademo. It should have:
  Intro, techno part, traditional part, credit part and an end part.
  Obligatory stuff for a megademo ofcause.
  The techno part, which was also designed, directed, and EVEN contains musical contribution by Dr.Who, became most interesting part of the project.
  After watching Front 242 on "100 minutes" on MTV we got the idea of making such techno and adding child drawings on.
  That became "M0mb".
  This demo is actually an A1200 compatible re-release of this sub part.
  More info about this megademo when someone uploads it on Pouet :)
  
  What does "M0mb" mean?
  Dr. Who (my brother and only 'real' memmer of GFB. Al other are fictive (used by me)) had a dream. (Or nightmare..?)
  He dreamed that Depeche Mode had released a maxi single, and on the B side was a song called MØMB (With 2 dots above the 'B')... probably inspired by 'Behind The Wheel' where there are 2 dots above the 'T'.....
  Or was it JM Jarres' Zoolook maxi he dreamed about? can't remember.. have to ask him one day...
  
  Well, its 30+ years ago... If i remember more details, I will add them.

• At 7:29 there is a yellow that is green inside. 2 bpl for the outside yellow faces, and 2 bpl for the green faces. Thats 4 bpl :)

• demo Amiga OCS/ECS Karbad by Light
• By the way..
  Steel, you actually tried to participate with 2 parts..
  but sadly the sourcecode disc disappeared during the party..
  One of the parts, "Total bobcall" was remade for our second megademo. :)

• demo Amiga OCS/ECS Karbad by Light
• Our first megademo!
  We were so optimistic to believe we could finish half the megademo, including trackloader, at the party. That was an important lesson :) Always make the important/tricky things first in the process!
  Mabye Chain was considered swedish because there also is the (famous) swedish c64-group called Light.
  A funny story about that:
  At that Dexion party, we were in a classroom, working on the demo. We were quite unknown, but then 2 guys entered the room, and one of the asked if we had anything to do with the swedish group "Light"..
  We looked surprised and scared, because the one who asked looked a bit scary.. "No.. we a are a new formed Amiga group..."
  I feared troubles with the swedish cracker underworld or whatever could happen..
  But then that guy presented himself. He was "Fox" from Dominators. A really nice guy. He was very interested in our new productions, and he told us his whole scene-life story.
  
  Is that really 26 years ago... ? That must be nostalgy..

• I like the music, its great! Godt gået, Frank.
  And congratulations with the 3. place, Søren. :)

• demo ZX Spectrum Gm BiT
• The Spectrum has a bitmap with 8 pix per byte, like the C64 hires screen.
  But it is true that the color-screen is a character screen excatly like the C64, so you guessed that right :)
  
  This scroll princip should be easy:
  Draw (up to) 6 rows of sinus plots based on the 5 pixels font, and then do a logical eor/xor vertical fill of the whole screenarea.
