The Legend Of Zelda: Ocarina Of Time's PC port is now available.
To avoid Nintendo's cease-and-desist, it's up to the user to extract the original N64 ROM (or download it from somewhere), so then it's on you, not them.
The software then extracts the necessary data from the ROM, and generates a version that is native to PC. It then adds HD graphics, ultra-widescreen resolution, keyboard support, modding support, force feedback and gyroscope aiming.
Text-to-speech, 60fps visuals, twin-stick camera controls, HD models and audio, texture packs, and support for Linux and Mac are in the works.
