m64 — projects

projects

Unusual systems at the intersection of low-level engineering and creative computing — mostly in Zig, mostly open source. A terminal graphics engine and the demo that ran on it at Assembly, a true-color video player, a Commodore 64 emulation stack, a tracker, a theory lab and a wiki for chip music, and a terminal game. From a 1982 sound chip up to neon at 60fps in a text terminal.

engine & graphics

movy — the engine — and the terminal-graphics work built on top of it.

movy v0.3.0

Terminal pixel-graphics engine for 60fps neon animations and games (Zig). A float framebuffer with a persistent glow buffer — bloom and neon trails for free — half-block rendering, headless-first. The foundation everything else runs on.

#zig #engine #terminal

movycat public

Full-motion video player for the terminal, in true RGB (Zig). A real-time decode → buffer → sync → display pipeline that even handles the hard parts: seeking across keyframes and pausing a live decode.

PIXEL LOVE 4th place

A terminal demo prompted into existence: 177×49 characters become 177×98 pixels at 60fps for exactly five minutes, in a text terminal. All demo code written by Claude Code in 782 prompts — on movy, the hand-written engine underneath. An AI's love letter to the demoscene. Binaries and readme on the page.

chip music

The Commodore 64, brought to Zig — emulate the CPU, then the sound chip, then play real C64 music. And then the rest of making it: a tracker, a theory lab that speaks tracker, and a wiki on how chip music is done.

zigreSID v0.5.0

Authentic MOS 6581/8580 SID emulation in Zig: load and play real C64 .sid music, render to WAV, and mix up to 256 live WAV effects into playback for game audio. Built on reSID + zig64.

zig64 v0.5.0

A cycle-accurate Commodore 64 MOS 6510 CPU core in Zig — CPU, RAM, raster timing, SID register tracking, and a disassembler. The metal under zigreSID. As low-level as it goes.

DUET v0.1.0-alpha web player

Impulse Tracker and SID-Wizard on one grid — two real trackers, one clock, one save button. The .it side from ITTECH.TXT, the SID-Wizard side reimplemented from Hermit's 6502 player and verified register-for-register through reSID; up to four SID chips as pattern columns. Repo's private for now — hear it in the web player.

0 3 7 lab live

Is 0 3 7 the right chord on every note of the scale? No. A one-file Web Audio app that teaches scales, chords and melody in the only unit a tracker needs — and pastes straight into OpenMPT, Schism or DUET.
