The Legend of Zelda: Ocarina of Time (USA 1.0): Patched The Legend of Zelda: Ocarina of Time (N64) for higher frame rates with Claude Code A fan patch called OoT HFR raises frame rates in The Legend of Zelda: Ocarina of Time (USA 1.0) on N64 hardware while holding game logic at the original 20 updates per second, and was built with the AI coding agent Claude Code on top of the Ocarina of Time decompilation project. The browser-based patcher at 64-bites.github.io/oot-hfr requires a legally obtained USA 1.0 ROM (MD5 5bd1fe107bf8106b2ab6650abecd54d6) and has been tested on FPGA N64 hardware, original N64 consoles and the ares emulator. Sword trails and some effects still update at 20 frames per second, and motion artifacts remain in water textures and animations such as the Biri jellyfish tentacles. Evidence at a glance Loading source evidence… What was done A fan patch for The Legend of Zelda: Ocarina of Time USA 1.0 that enables higher frame rates on N64 hardware while maintaining original game logic speed. Developed using Claude Code and the Ocarina of Time decompilation project. OoT HFR is a fan patch for The Legend of Zelda: Ocarina of Time USA 1.0 designed to increase frame rates on N64 hardware. The patch maintains the original game logic at 20 updates per second, ensuring the game speed remains consistent. The project was developed using Claude Code, an AI coding agent, and utilizes the Ocarina of Time decompilation project as a base. The patcher, available at requires a legally obtained USA 1.0 ROM to function. It has been tested on FPGA N64 hardware, original N64 consoles, and the ares emulator. While the patch enables higher frame rates, certain visual elements such as sword trails and specific effects continue to update at 20 frames per second. Additionally, some motion artifacts remain visible at high frame rates, including specific water textures and character animations like the Biri jellyfish tentacles. Reproduce it 1.
