Competition Entry This was a competition entry in 2024

I don't have as much time to code as I would like. but I didn't want to stay this year without presenting anything. Here is a little demo of unpretentious experimentation on dithering. Everything is not stabilized yet, but it looks pretty good at 60 Hz, even if it still shakes a little on real hardware (even more at 50 Hz). The demo is coded in C thanks to the sverx kit so there is ample opportunity to refine this technique in ASM. We see in the title that it is possible to generate the illusion of additional colors and transparency in the dragon's fire and a little in the lettering (same method as for the water cascades in Sonic on Megadrive). The music is a cover of heroquest that I wanted to include in the homebrew Grail of the Gods but which was cut during editing because it did not satisfy me. For posterity I included it in this demo. Press 2 to turn the effect off and 1 to resume it. Have fun.
