https://www.entropicengineering.com/defcon-32-statement> The specifics of what they requested in January were extremely difficult / almost impossible, but we had been working with Raspberry Pi as a Design Partner and had early access to the unreleased Raspberry Pi RP 2350, a chip that would enable exactly the kind of device DEFCON was requesting. Dmitry and Entropic had already been working on a GB emulator and were thrilled to be able to contribute our work to a project directly for and by the community.

> Despite the near impossibly short timeline to achieve 30k unit mass production, our team of 5 worked tirelessly alongside Dmitry. He handled all of the emulator software while we sourced components, designed all of the hardware, wrote production test software, and organized all circuit board manufacturing, prototype manufacturing, facilitated large volume production manufacturing and logistics, and general project coordination. Through this period, Defcon’s responsibility was the game-specific software, badge accessories (i.e.: plastic case and lanyard), and the printed circuit board artwork including the cat shape, colors, and silkscreen.

It appears that Defcon contracted with Entropic. Entropic was working with Dmitry.
