Factory DS

项目介绍

Factory DS is a Factorio-like factory game that runs on a real Nintendo DS: a 67 MHz ARM9 with 4 MB of RAM. The author had never written DS code before: he wrote the specs, the design and the balancing, and Claude wrote most of the C — his words, verbatim from his Show HN post. Technical highlights: a 2048x2048 world that is never stored (terrain is computed from x,y, only player changes kept in a hash table); night done by swapping the 256-color palette instead of redrawing; power grids and pipes computed per network with union-find; trains with schedules, block signals and pathfinding; redstone-like logic gates. A headless Mac build with a text interface let AI agents play ~470 test sessions and even helped balance the game. The ROM (English and French, 1.9 MB) downloads from the project page and plays on a flashcart or the melonDS emulator. Note: there is no GitHub repo and no in-browser demo — the game ships as a downloadable ROM.
