m64

Hi, I'm m64.

I love pixels. Started pushing them around on a C64 in assembly. Never stopped loving the low level. Now I write systems code in Zig — low-level networking, emulators, terminal graphics, the occasional game. When not coding, I'm soldering ESP32s or making chiptunes in trackers — on Game Boys, on the C64 with SID-Wizard (and now DUET), and on an M8.

init

Systems programmer in Vienna. C64 assembly → Intel assembly → C/C++ → Zig. I love building unusual systems at the intersection of low-level engineering and creative computing.

Most of what I make lives in the terminal — and a lot of it runs on movy, an engine that renders glowing neon at 60fps in a text terminal.

movy
Terminal pixel-graphics engine for 60fps neon animations and games (Zig). The foundation everything else runs on.

PIXEL LOVE
A terminal demo prompted into existence — 177×98 pixels at 60fps for exactly five minutes, every line of demo code written by Claude Code, on movy. 4th place at Assembly 2026.

sound

The other half of the 64 is the SID. I make chip music in trackers — so I built one, plus a theory lab that speaks its language, and a wiki on how all of this is done.

Chiptune Wiki
How chip music is made — SID, Game Boy and PC trackers: techniques, tools, theory in tracker terms, formats, history, people. An LLM wiki: sources in, cross-linked pages out.

0 3 7 lab
Is 0 3 7 the right chord on every note of the scale? No. Music theory in semitones, for tracker people — one file, in the browser, pastes straight into your tracker.

DUET
Impulse Tracker and SID-Wizard on one grid — two real trackers, one clock, one save button (Zig). The repo's private for now — hear it in the web player.

i/o

Electronics background — I like to play around with ESP32, STM32, and similar. Bridging circuits, code, sound, and pixels. The 64 is the Commodore 64: where the love of pixels and the low level started, and never left.
