As seen at DevDay

First introduced as a DevDay exclusive, the ModRetro Chromatic: Codex Edition quickly became a standout favorite. Now, it’s back with a new look as our latest Supply Co. drop.

From an idea to a cartridge

You bring the imagination. Codex and the ModRetro Chromatic plugin help you build a game, test it, and put it on a cartridge.

  1. 01 / Imagine

    Start with a prompt

    Describe the world, the characters, and how you want to play.

  2. 02 / Create

    Build with Codex

    Add the ModRetro Chromatic plugin to help turn your prompt into a game.

  3. 03 / Refine

    Make it your own

    Work with Codex to shape scenes, art, and game logic in GB Studio.

  4. 04 / Build

    Ready, set, ROM

    Build a ROM: the game file you can test, share, or load onto a cartridge.

Three ways to play

  • On your computer

    Play. Tweak. Repeat.

    Try your game in a browser emulator. Tell Codex what to change, then play again.

  • On your Chromatic

    Get a feel for it

    Stream your game from your computer to Chromatic to test its controls, screen, and sound.

  • On a cartridge

    Take your game with you

    Write your ROM to a Codex Cartridge, then play it on Chromatic without your computer.
