The handheld Game Boy console has seen widespread popularity, with over a hundred million sold. It continues to be relevant as a retro-computing platform, and through emulation a Game Boy ROM can be run in the browser. However, despite being a well-defined, stable platform, there have been very few procedural generation projects that target the Game Boy. By leveraging existing ecosystems of development tools for the Game Boy platform, we construct a game generator that outputs playable ROMs. Paired with this, we seek to improve the ecological validity of game generation by building a generator that acts as a bridge to an active community of non-academic developers. The system interprets and outputs the same data artifacts used in the wild, allowing it both learn from andcontribute to development communities, as well as tapping into the corpus of existing design work.
