256B Fullscreen Scroller

Mon, 17 Oct 2022 20:27:34 +0200

Here comes my contribution to the Sommarhack 2022 Online party…

Certainly not the most original screen in the world, but it is the first full overscan scrolling (without syncscroll), packed in less than 256b.

This program respects the general bytetros rules : 224b code + 32b header = 256b executable file !

Hi ! Here comes the remake from the screen “Let’s Do The Twist Again” by ST Connexion, released in the Punish Your Machine demo by Delta Force (Atari ST, 1991)

It was one of the very rare screens by ST Connexion (their first one since 1989), and is a technical masterpiece, featuring “4-bit syncscroller” for the first (and only time) on the ST, a technic that allowed to shift the screen by increments of 4 pixels, whereas a “classic” syncscroller had a 16 px accuracy.

Alien of ST Connexion did a series of articles about overscan in ST Magazine, a French publication, that were partially translated in Alive diskmag 9 & 11.

Wed, 24 Jun 2015 15:13:22 +0000

Here comes my Codef remake of the README.PRG screen from The Exceptions (TEX), released in 1987.

This demo was one of the very first demos on the Atari ST by the ST godfathers: The Exceptions, the crew that dominated the early years of the ST demo scene.

With this demo, the age of Atari ST demos began ! The Exceptions were the inspiration for a whole generation of demo programmers.

The budding rivalry with the Amiga can be seen in the dragon flaming the Amiga mascot.

I hope you’ll like it !
