Ship one downloadable .img that boots correctly on every supported Raspberry
Pi, instead of asking users to pick the right per-board image. Each board must load
only its own OS into RAM — never the whole file — so the per-boot RAM footprint is
identical to today's single-board images.
This document is a build-test-PR proposal for upstream SeedSigner OS.
Over roughly four to five hours of active work spread across a couple of days, Keith used Claude Code to port the game "2048" from an open-source Javascript implementation to a C/C++ version that runs on an inexpensive ESP32-S3 microcontroller. Claude wrote all of the resulting code. But the reality of the collaboration is more nuanced than that number suggests.
Claude was fast at producing working code — display drivers, build systems, CI pipelines, animation logic — generating in minutes what would have taken Keith days or weeks to do by hand. It could hold dozens of files in context and make coordinated changes across all of them. When the game crashed with a cryptic memory dump, Claude decoded the call stack and traced the bug to a specific line where a division by zero was happening inside the graphics library. This is expertise Keith does not have. It was also good at grunt work: converting font files, writing build configurat
OTFs have to be converted to TTF first.
