Chip&Dots by Oxygene
(party version)
A tiny 32KiB intro for Amiga 500
Released at 68k-Inside 2025 party
Code & Design:
Leonard / Oxygene
Graphics:
Mon / Oxygene
Atari ST Music:
BigAlec / Delta Force
This 32KiB demo is made for Amiga 500 OCS but should run on any other Amiga
Fun Facts
---------
- This intro has been made because of the "3d demo 3" breaking my previous
dots record. I was really impressed by Hannibal version so I scratched my
head for days to find another approach
- The YM2149 emulator used here is a PAULA only emulator (no CPU involved)
It could support one TONE+ENV voice (classic Atari bass-buzz) but also
a SID voice (but a single one)
- The TONE+ENV classic "madmax" buzz bass is done using an almost never
used PAULA feature. I'm using one PAULA voice to modulate the volume of
a second PAULA voice. This chip is great!
- During dots part, the YM2149 emulator is fully copper driven
(no CPU used at all)
- Full technical details in the ending scroller coming soon in final version
Thanks to
---------
- Soundy for testing on real A500 hardware!
- Shrinkler for packing all these tiny bytes
Enjoy!
