RETROCODES — the holdings of retrocodes, 26 pieces. Words of the house: shipped whole.

I — The Great Houses

machine-room
A Game Boy emulator: SM83, scanline PPU, four-voice sound, in 1,164 lines with no dependencies. Passes Blargg's CPU tests and renders dmg-acid2 pixel-perfect. Insert a cartridge.
2026 · ZERO DEPENDENCIES · HARDWARE-TEST VERIFIED

sculpture-hall
A 3D renderer with no GPU: matrices, near-plane clipping, z-buffer, perspective-correct texturing, written longhand. Walk the hall, or drop your own .obj onto the plinth.
2026 · ZERO DEPENDENCIES · ZERO WEBGL · 36 TESTS

NebulaStreams V2
Hybrid streaming server: torrent streaming, HTTP proxying, and a disk-backed cache.

One streaming player, four rooms: web, Android, desktop, and a shared watch-party.

A Spotify-style Monochrome client packaged as an Android app.
2026 · JAVASCRIPT · ★ 2

II — The Small Council

graph-graffiti
Draw text and sprites on a contribution graph in backdated empty commits. The studio behind the arcade wing, cleaned up and handed to visitors.
2026 · NODE · ONE FILE · ZERO DEPENDENCIES

arcade-cabinet
Space Invaders in the terminal. The invaders on the graph don't move; these do.
2026 · NODE · 385 LINES · ONE COLOR SPENT ON BULLETS

print-room
A poster press. Every visit prints a numbered edition from the collection's identity; the number in the URL is the poster.
2026 · ONE HTML FILE · EDITION OF ONE

the-vault
The storage basement, navigable entirely in markdown. The receiving books run to 27. This page says 26. Someone should look into that.
2026 · NO CODE · 17 ROOMS · ONE MISSING EXHIBIT

III — Beyond the Wall

North of the Wall, in storage: an emergency-line triage engine, an app that locks a phone against its owner's worse instincts, an invoice tool on its second payment processor, an intent radar for a noisy social network, and a reorder planner for shopkeepers.

STORAGE IS NOT EXILE · PIECES RETURN

IV — Send a raven

The realm is kept by one person. Every holding accepts issues and pull requests; that is how a raven is sent. New pieces appear without banners.

THE GATES ARE ALWAYS OPEN · NO TOLL
