Atari 800 Winter Solstice Celebration Demo
- 23 December 2022
Every December, I try to make a little wintery demo to exercise one of 8bitworkshop’s platforms. This year, I chose the Atari 800 to test out the new native TypeScript emulator in 8bitworkshop. You can see the demo emulated here.
I revisted my Bally Astrocade “Happy 2020” Demo, which simulates falling snow. It uses pixel-level collision to simulate each falling particle, which creates neat little piles of snow and particles that ripple off the sides of obstacles.
Atari ANTIC Mode $F uses the GTIA chip to add additional modes beyond what the original CTIA chip provides. I used GTIA Mode 10, which is 80 x 192 pixels with nine different colors.
