Claude rebuilds Ocarina of Time's Kokiri Forest inside Valheim, zero code written

Any-Explanation3814 · reddit · 2026-11-10

A player had Claude spend 5 days building an importer that converts their own Ocarina of Time ROM into a playable Valheim mod covering Kokiri Forest and the Deku Tree — without writing a single line of code. The pipeline uses the zeldaret decomp, a Python N64 display-list interpreter, Cenemy ports, BepInEx for Zelda mechanics, and a clever self-testing loop where Claude launches Valheim, teleports, screenshots, reads logs and fixes bugs autonomously. Not yet public pending legal review.
