OpenAI Codex x ModRetro Chromatic: build levels, sprites and ROMs on a handheld
graceisford · x · 2026-11-11
OpenAI's dev account announced a collaboration with ModRetro, the retro handheld company backed by Lux: the Codex-edition ModRetro Chromatic handheld is now available on Supply Co. A ModRetro Chromatic plugin in Codex lets developers design levels, animate sprites, and playtest directly on the handheld, while Codex builds the ROM — a novel way of wiring coding agents into hardware game development.
