OpenAI and ModRetro launch Chromatic Codex Edition handheld at $200

Build a game, then play it on the console

The idea is that owners make their own games instead of only playing existing ones. The workflow starts on a PC with the Codex app and a dedicated plugin, which is used to create the game. The result can then be tried out in an emulator that runs in the browser.

Once the game works, there are two ways to get it onto the hardware: transfer it directly to the console, or write it to the included cartridge and play it the traditional way.

Hardware and compatibility

The Chromatic is also compatible with Game Boy and Game Boy Color cartridges, so existing games can be played on it as well. The screen is a 2.56-inch IPS LCD with a resolution of 160 × 144 pixels, matching the classic Game Boy format.

The handheld was first shown at a recent OpenAI event, and the announcement now turns that preview into a product people can order. The $200 price puts it in the territory of a dedicated retro console rather than a casual accessory, and the writable cartridge is what sets this edition apart from a standard Chromatic.

For developers and hobbyists, the appeal is a short path from an AI-assisted coding session to a physical game running on real hardware. The sell-out suggests early demand is strong, and buyers who missed the first batch will have to wait until the restock on the 19th.
