OpenAI and ModRetro Let Developers Build Game Boy Games With Natural Language at DevDay

OpenAI and ModRetro announced a major collaboration at DevDay 2026, enabling developers to create playable retro games using Codex, the AI coding platform, integrated into the Chromatic handheld console. The Chromatic, a Game Boy Color-inspired device with a custom LCD display and aluminum construction, received a dedicated Codex Game Studio plugin that allows developers to describe game concepts in plain English, test them with an emulator, and write finished titles to physical cartridges.
