A 4KiB FullScreen & DigiSound & MegaScroller Atari STE intro
Released at Silly Venture 2022
(party version)
Code & Design:
Leonard / Oxygene
Music:
Virgill / Alcatraz
This 4KiB demo runs on Atari STE with at least 1MiB of RAM.
This tiny 4KiB executable contains a fantastic 25Khz, mono, 8 seconds
digisound loop! Tribute to the awesome Cuddly Demos Fullscreen by TCB.
Technical details:
------------------
The key feature of this 4KiB is the digital audio sound.
I came recently with the idea of using softsynth to produce oldskool
digisound loop, as in good megascroller time. The loop is in reality
a very small amiga MOD file, pre-rendered at the beginning. The music
is made using the great AkLang tool by Virgill / Alcatraz. At the very
beginning, samples are generated using the soft-synth (thanks to
Aklang2asm by Dan / Lemon.)
Then, LSP is running the music and a tiny Amiga Paula emulator is
rendering audio stream in memory. (LSP is my tiny & ultra fast MOD
player technology I originally made for Amiga)
When everything is ready, I just have to play a pre-rendered audio
sample using classic STE DAC. No CPU time required at all during
the demo :)
Then some generated integrated blitter+fullscreen code to display
Y dist megascroller, some emulated copperlist to X dist in fullscreen,
and finally pack everything in a small box using STrinkler and you're
done :)
Fun facts:
- When I came up with the idea of oldskool sound loop, I showed
a youtube version of TCB fullscreen to Virgill. And he did a MOD
file with AkLang in like a few minutes :)
- Thanks to Little_Rabbit for testing on real hardware! I didn't even
knew you had an Atari STE! Shaq-Fu rules forever!
