Hi to ATARI & GFA basic mates :) This week-end, i share the last of the 7 compiled gfa demo / screens of Japemo unfinished Atari ST Megademo, another average demo i've mainly coded between in 1996-99 if i remember well, but one more time stopped because too many bugs / unable to compile it at that time) : Nfi DenTrO Arranged to be a little faster, with several bugs removed and compiled ~15 years after. Video recorded with Hatari emulator (STe) and upscaled to nearest neighbor with ffmpeg about 2-3 weeks ago. Low design, slow / heavy effects, far not enough polished / optimized, hasardous japanim old gfx, bugs, but a very nice chiptune music : Wonderland Speedway by DMA SC Very big & big sprites, bouncing-bumping-jelly raster like deco, animated hlines colourful waves raster like, animated atari zooming checkerboard, dis/appear fx, or fx, full picture vertical distortions, stars + night lines + bubbles, dotted object bouncing moving + 'voxels' waves, dancing colorful lines & rectangles, vertical scroller with ugly curves plotted, rough v disto / wave, unlimited bobs, 4 planes sprites moving + ascii text color waves , ... Japanim / manga style gfx. Kinda lazy demo Code & Gfx : Hylst Music : Dma-Sc Should run on ATARI STf 520.

This evening, i present you an ATARI ST intro i've coded in GFA between in 1996-99 if i remember well ( 22-26 years ago !! ) : LaRquOry demo Arranged to be a little faster, with several bugs removed and compiled ~15 years after. Better quality of video recorded this week with Hatari emulator (STe) and upscaled to nearest neighbor with ffmpeg. Low design, overall old (around 1996 and before) bad quality graphics, slow / heavy effects, far not enough polished / optimized, bugs, but a cool chiptune music by Frazer : i thought by mistake it was from DMA SC which is a very good chiptune composer, but i was wrong this time... Memory flies through age and more ^^ Coded as a screen for unfinished JAPEMO GFA Megademo. Star wars dot scroller, field of dots, 3d dotted landscape trip, sprite + vu meter + basic screxx, binary falls + bouncing message greetings display, parallax scroller with sprites wandering, plasma like in window, nested ascii waves of text, lines & dots waving, turning, dancing, vertical checker straight or crossed diagonal along vertical waves, kinda 'shades bobs' agitation, the tree moving on wind (not my code, just adaptation for fun), dragon wavin' smokes + 1bit horyzontal screx ,... Japanim / manga style gfx. Kinda lame / lazy demo though 8S ^^ Own production. Code & Gfx : Hylst Music : Frazer (not DMA SC, my mistake) https://www.youtube.com/watch?v=8WGzl4wu__s

After my old Japemo hasardous ATARI ST demos, it's time for my 10 years old 'only' gfa demo to be shared with you with a far better recording quality than old one :

∙∙ ∙∙ ∙·▫▫ᵒᴼᵒ▫ₒₒ▫ᵒᴼᵒ▫ₒₒ▫ᵒᴼᵒ☼)===>

MAXMUM VBL - GFA demo

¯\_(ツ)_/¯

for Sommarhack 2011 Online ATARI ST Demo Compo

A Gfa Demo for ATARI ST 1040

( 4 Mega tested, but should require only 700kb) or more / ST LOW )

But it seems it don't work on 1040. Dunno remember why presently)

Code & Gfx : Hylst

Musics by DMA SC :

Pocket Groove

Craufunk

Pre Midnight Piza

& 'ripped' sample at 22khz

Effects :

('basic' effects, but various, nothing especially amazing,

the goal was to do it for fun with GFA)

Raster scroller, disco effect, matrix effect, text wave, horyzontal starfield,

sprite+equaliser+scrolltext, snoweffect, zooming, rotating, distorting 2d/3D logo,

x / y bitmap distort, zoom y bitmap, 'mad' distortingx&y smoke distort, optimised effects, 2 kind of dotted flexiscrollers, fakeplasma, chesslines grooving, blob,

3d with late path 3 objects, dotfield swing, rotating & shading stars, " painting,

vectorbals with 3 objetcs, and border deform, circular dotted scrolltext, 3 stars rotating, moving, swing'in, unreadble screxx with deformation, mirror & zoom, greetings screen with dancing & wavin'sprite flexiscroller + few effects od distort and bump, raster screen with raster bars & sample, color scrolling, screen moving, ... .

13 pictures + few design gfx (yes ! At least ! i try to design my demo =p)

Few bugs that can occur one time and not next...

Rushed so effects with most bugs had to be removed, ... For a next demo...

Maximum Vbl... is not exactly realtime 😃

But i'll try to become better & better ! 😊

It's anything but extraordinary, but it's my style... heavy...

However, it required a lot of work & time so...

Hope it will please you 😊

4T4R1 ruleZ !

https://hylstlair.fr/wp-content/uploads/ZIP/MAXIMVBL.zip

Don't forget to copy DATA repertory with MAXVBL.PRG.

(It should use 600ko+ memory, + 20% only of effects uses Ste specific)

Many thanks to Nicolas Flandin (TOMCHI) and Lonny Pursell for their precious help in code / debugging / compiling at that time !!
