I replaced Animal Crossing's dialogue with a live LLM by hacking GameCube memory
How I replaced Animal Crossing's dialogue with a live LLM by bridging GameCube memory to a cloud AI, with no game code changes required.
I chose the RAM mailbox because it's deterministic, requires zero kernel/driver work, and stays entirely within the emulator boundary, with no binary network stack needed. The decoder could read raw game memory and translate it into a human-readable format, and the encoder could take my text with custom tags and convert it back into the exact sequence of bytes the GameCube understood. It receives a detailed character sheet (which I generated by scraping the Animal Crossing Fan Wiki) and focuses on writing dialogue that is funny, in-character, and relevant to the context.
