OpenAI began selling the $200 ModRetro Chromatic: Codex Edition on November 9, pairing a retro handheld with a cartridge that users can flash with games made using Codex. The product page showed “Restock soon” on November 10 and listed November 19 as the expected restock date. Sales totals, available stock and whether that date will hold are unknown.

OpenAI began selling the $200 ModRetro Chromatic: Codex Edition on November 9, pairing a retro handheld with a programmable cartridge for games created using its Codex coding agent. The product page showed “Restock soon” the next day and gave November 19 as the expected restock date, though OpenAI says dates may change.

The edition is sold through OpenAI’s Supply Co. shop and includes a transparent-shell ModRetro Chromatic, one programmable Codex Cartridge and three AA batteries. The handheld has a 2.56-inch, 160-by-144-pixel display and plays Game Boy, Game Boy Color and Chromatic cartridges. OpenAI lists a separate carrying case for $35 and an extra Codex Cartridge for $50.

OpenAI’s advertised workflow starts with a plain-language game prompt. Users add the ModRetro Chromatic plugin in Codex, then refine scenes, artwork and game logic in GB Studio, export a ROM and test it in a browser emulator or on the handheld. To play independently of a computer, they can write the ROM to the included cartridge. ModRetro’s quickstart instructions also call for a firmware update and an activation code to enable Developer-Mode.

The product page said the device ships to the United States, Canada, Australia, New Zealand, Japan, the United Kingdom and the EU. OpenAI says warranty and support are provided by ModRetro, and its listing says non-defective items cannot be returned. Writing a new ROM erases the cartridge’s existing game and may erase its saves; the installer does not back up the cartridge.

A Prompt-to-Cartridge Workflow

The bundle makes a Codex use case tangible: a person can describe a game, work on its code and assets, and run the result on a dedicated handheld. OpenAI’s developer material shows Codex helping with tasks such as creating sprite sheets and editing collision maps, while the plugin includes a sample game users can remix. That presents the handheld as both a gaming device and a way to demonstrate the coding agent’s capabilities.

For buyers, the practical draw depends on whether that workflow is accessible and enjoyable. The device does not remove the need to install software, update firmware or work with GB Studio and ROM files. It does offer a route from a prompt to play on physical hardware, a different experience from simply testing a generated game in a browser.

From DevDay to Retail

OpenAI says this edition was first introduced as a DevDay exclusive and later returned with a new look. The source material reports that attendees received a DevDay edition at OpenAI’s developer conference on September 29, 2026, the same day ModRetro announced the collaboration. OpenAI’s developer forum introduced the retail sale with the phrase “By popular demand.”

The Chromatic is ModRetro’s handheld for Game Boy and Game Boy Color cartridges. ModRetro describes its FPGA-based hardware as playing original cartridges “with 100% accuracy”; that is the company’s claim. On November 10, its store listed a transparent Chromatic bundled with Tetris for $149.99, while other Chromatic and Tetris bundles started at $199.99. OpenAI’s listing includes a programmable cartridge but does not mention Tetris.

OpenAI has also published 13 Codex-made games for the Chromatic, according to the supplied source material. They can be played in a browser or downloaded as ROMs; the product page highlights a tile-matching puzzle, a dungeon crawler and a rhythm game featuring the Codex mascot.

Stock and Sales Remain Unknown

The listed November 19 restock date is an estimate; OpenAI says restock dates may change. The source material does not say how many units were available, how many sold or how many are planned for restock. It also does not establish whether demand will continue after the initial listing.

It remains unclear how much coding experience buyers will need to get from a prompt to a finished game, or how reliably Codex can produce games that run as intended on the device. The product materials demonstrate a workflow, but provide no independent performance assessment or measure of how much assistance users may need.

The Listed November Restock

As of November 10, buyers were directed to check Supply Co. for a planned November 19 restock. The date may change, and the supplied material gives no confirmed quantity or later availability schedule. OpenAI and ModRetro’s published setup guides and game examples offer the next available detail for people considering the device or trying the workflow.
