What happens when you point an AI coding agent at a classic NES game and say “build this”?
I wanted to push the limits of AI-assisted development. The challenge: recreate the original Legend of Zelda as a fully playable browser game, written entirely in TypeScript, using nothing but Ralph — an AI coding loop — to write the code.
The result? A working Zelda game built in just 2 Ralph loops. Two iterations from zero to a playable game with movement, combat, room transitions, enemies, and the iconic overworld. No manual coding. No copy-pasting from tutorials. Just AI and a prompt.
I documented the entire process — every prompt, every iteration, every surprise — in a YouTube video and blog post. Whether you're curious about AI coding tools, game development, or just want to see Zelda running in TypeScript, this is for you.
