A demo is usually a program coded for fun or/and for technical challenge, or/and to share a passion,
with design, digital art & music.
Most of my demo were realized for ATARI computers about 25 years ago
They belongs to a whole set : a big megademo which was never finished.
About to come one day 4 advanced Work In Progress demos :
– a music demo for Falcon (GFA + ASM + C (?)) with fire effect, 3D shaded, truecolor pics & effects, soundtrack, picture realtime distortion, rotozoom, etc.
– a big (GFA + ASM) demo called Reheat based on several effects from Japemo optimized with better design
– No extra crime a designed 128k Atari ST demo
– In the beginnings a 64k Atari ST demo
Mainly a matter of (quiet) time to find (continuous time, not an hour one month and another the following…)
So, my produced ‘finished’ Atari ST demos are :
GFA demo on ATARI 1040 STe 2011 for Sommarhack 2011 demo competition
(not ranked at that time because of bugs on real hardware / Hatari)
Code & Gfx : Hylst Music : DMA SC
Please take care : executable is not last version, link will be updated
LARQUORY DEMO
for Japemo (1999) revisited in 2011
coded in GFA – for ATARI ST
Code & Gfx : Hylst Music : DMA SC ?
(faster on STe….)
Hylst Vector Demo on ATARI ST (1994) GFA /ASM revisited in 2011
Code & Gfx : Hylst Music : DMA SC
With many of my GFA demo, i’ve encountered a lot of compiling bugs i could not explain. (well running interpreted but…)
I should work on it again cold-headed…
Hylst Dot Demo on ATARI ST / 1995 GFA /ASM revisited en 2011
Code & Gfx : Hylst Music : DMA SC
In 3 parts dot colors are so dark thats it’s hardly perceptible on (LD) video
Another easy modification without avoiding to use cls & bmove on whole screen to erase after each display several effects !! 😁
