• 32b Atari XL/XE TV Noise Anthology by JAC! [web]
• 
  Maybe even some of those people whose did not think I've gone mad yet, will now starting thinking like that. But it just had to create it after all this positive reactions ... and to put the TV noise battle at a final ending:
  
  >>> TV Noise 2010 (i)nteractive <<<
  
  You can control the tuning of the TV set via the paddle in port 0. For those who are not old enough to know what a paddle is, see Wiki. And since hardly anybody will have one today, there's also youtube of course. And yes, it's still 32 bytes.

  Now could you try to make a fullscreen version so that there is no frame?

  
  Just run the 2010 version on the real headware. It does not have a frame and really loses the TV sync. The video is recorded from the emu because I have no camera, so you just cannot see it there :-)

• Yeah! I finally found the hidden part and ported it to my Atari 800, hehe. I love those things which give me inspiration ;-)

• This pack contains the complete TV Noise anthology
  So please do not take it serious, hehe.
  Those who neither have an Atari nor a TV set can use youtube.
  
  >> TV Noise 1987 <<
  
  It's Saturday night and I needed some distraction from coding so I surfed on Pouet.
  You wouldn't imagine what was going on there.
  Somebody wrote ".... who can't even code 10 lines of code".
  Somebody else wrote "Make it in 32b next time".
  
  So I had to do it - in 10 lines of code and 32 bytes ;-)
  
  This one is actually from 1987 when I got my first assembler book
  and found out that the Atari has a random register. Today I would
  say "it's not a release it's just an effect" - know what I mean...
  
  
  Code: lda #$40 sta $bc25 ;Move screen to $4040 sta 756 ;Move charset to $4000 loop lda $d20a ;Random sta $4000,x sta $4100,x sta $4200,x sta $4300,x inx bvc loop
  
  
  >> TV Noise 2010 <<
  
  On your B/W TV with real sync it looks and sounds like this.
  
  Code: loop lda #$c3 ora $d20a ;Random sta $bc25 ;Move screen beyond $c300 sta $d409 ;Change charset sta $d400 ;Overscan distorsion sta $d201 ;White noise asl $d200 ;Frequency lsr 710 ;Black background bvc loop
  
  
  >> TV Noise 2011 <<
  
  Broken DRAM on your 30 year old Atari looks like this.
  Since the DRAM is broken, I had to pack this one into 16 bytes.
  
  
  Code: loop lda #$c3 ;Ensure charset is in ROM area ora $d20a ;Random sta $d409 ;Set charset bvc loop

• demo Commodore 64 Cubase64 by Mahoney [web]
• @xernobyl It can do most effects at the same time. In the download archive there's a very good whitepaper which describes how it is done and what the limitations are.

• 32b Atari XL/XE Expanding Universe by JAC! [web]
• Thanks! And here are the lyrics, for those who are familiar with "ancient tongues".
  
  Code:* = $2000 loop inx ;Next double scanline wait cpx $d40b ;Wait for next double scanline beq wait stx $d012 ;Set missile 0 rainbow color and #1 ;Use lowest bit of previous line adc $00,x ;Carry will be set due to CPX sta $00,x ;ZP,x will wrap at $ff to $00 sta $d004 ;Set missle 0 horizontal position asl $d402 ;Reset DL low pointer to force blank line asl $d011 ;This will put "10" into bit 1 and ;0 because $d011 is trigger 0 bcc loop ;Carry is cleared due to ASL above
  
  
  The youtube is jerky as always due to the lame 30 FPS replay, so I recommend the use the real thing or and emulator. It took some time but the uploaded version now runs on both.
