demoports

Demos have been a large part of my life. Each of the demos below is curated by me, to relive these moments when I was a kid, rushing back home from school and dial up one of the local BBS’s and hope that a new demo has landed. And then I would watch on repeat, how did they do that? how is it so fast? Games back then weren’t as fast, so how these wizards pull these things off?

Each of the demos here mean something to me, that’s why I chose to port these. The work was done mostly by Claude Code with Opus 5.5 and Fable 5.1 models. I review each one of them, and compared captures taken by various people on YouTube, to make sure it matches the original as closely as possible. Nothing beats the real hardware, this is not a replacement. But this is also not emulation, it’s rewritten to play at the right speed on your browser, mimicing copper effects and crtc quirks. The code will set these values, and an engine would render the graphics.

I’m tempted not to look at the code. Some of the things here are still magic to me, and I’d like to keep this mystery for a little longer.
