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 !

Fri, 08 Mar 2019 15:15:49 +0100

A little return into the world of cracktros with this prod produced for Atari Legend…

4K 4-Bits Mega Scroller

Sat, 09 Dec 2017 13:15:02 +0000

This is a Mega Scroller, using the 4-bits hardscroll technique created by Alien/ST Connexion, but in just four kilobyte.

Yes, you read correctly: fullscreen, sync-scroll, parallaxed background, huge font and obsessing music, all of this in less than 4 Kb of code !

This screen was released during the SillyVenture demoparty that took place in Gdansk (Poland) on december 9th 2017.

(For more information, you will find explanations about the 4-bit sync-scrolling on the Atari ST Fullscreen demos history page)

128B Mandelbrot Set

It was released during the SillyVenture demoparty that took place in Gdansk (Poland) on december 9th 2017.

It was released during the SillyVenture demoparty that took place in Gdansk (Poland) on december 9th 2017.

Atari bytetros rules: 64b + 32b header = 96b executable file !

32B Sierpinski Triangles

Sat, 09 Dec 2017 11:14:58 +0000

This bytetro is a Sierpinski triangle pattern, drawn in less than 32b.

Atari bytetros rules: 32b + 32b header = 64b executable file !

32B Noise

Sat, 09 Dec 2017 11:10:58 +0000

The first 32b ever on Atari ST!!!

This is a revisit of the “noiST 64b” by Checkpoint, slightly improved to occupy less than 32 bytes…

A 26b version is also available (it is even possible to go down to 18b if you remove the palette change…

This bytetro was released during the SillyVenture demoparty that took place in Gdansk (Poland) on december 9th 2017.

Sommarhack 2017 Syntax Terror Big Border Revisited

Sun, 09 Jul 2017 11:17:04 +0000

Here is my contribution to the Sommarhack 2017 demoparty that took place in Grådö (Sweden) on july 8th 2017.

It was the winner of the “Syntax Terror Big Border Revisited” competition !

Back in 1990, Delta Force released the legendary Syntax Terror megademo for the Atari ST. The Big Border demo screen was coded by Chaos Inc and it’s main characteristics was the tiny 96*54 pixel screen size.

The rules of the compo were as follows :

The demo is limited to a 96*54 area, centered on the screen
No rasterbars outside of the 96*54 area
Must work on 512k RAM
Must work on Atari ST

Sync128B

Mon, 14 Nov 2016 12:01:29 +0000

Thoroughly stable rasters in only 128 bytes !

At the beginning of 1988, SYNC released a screen meant to showcase flicker-free rasters, named SYNC.PRG.

Here is my fullscreen tribute (working on Atari STF/STE), as a contribution to the Silly Venture 2k16 demoparty that took place in Gdansk (Poland) on november 12th 2016.
