"Bloom 612" a 256 bytes #Dreamcast procedural graphics shown at #lovebyte2025

3x additive HAKMEM 149 algorithm (all integers) progressively scaled up which render a blooming 🌺

"Dreamelt" 128 bytes #Dreamcast intro shown at #lovebyte2025

This uses the HAKMEM 149 algorithm, it draws with a fixed color and has a screen clearing pass that decreases the framebuffer values continually which result in colors cycling along frames.

Also released a 64 bytes #acornarchimedes intro with the same algorithm although it doesn't have the screen clearing pass : https://www.onirom.fr/wiki/codegolf/archismall/

@gorplop right now I'm still working on getting like a 1440kB 3,5" FDD relese (version 0.1) for #i486-SX done but in theory everything should just cross-compile to #SuperH 4 / #SH4...

I just wanted to make something more practical to use than #Floppinux whilst also making something a bit more versatile than #mkroot.

@ZiggyTheHamster I've heard someone doing some #ReverseEngineering on the #Dreamcast's #Ethernet adaptor...

Sadly that's complicated by the proprietary nature of the connector and the obsurity of #SuperH 4 (#sh4)-CPUs...
