How zeldaret/oot works

This repository is a work-in-progress decompilation of The Legend of Zelda: Ocarina of Time, not a PC port. Its runtime recreates the game’s boot and frame loop, gameplay and actor behavior, menus, graphics, audio, and platform services. The sampled sources show selected calls among audio scheduling, overlay loading, and the Wallmaster actor; other major game subsystems are represented from the repository tree and README, so their internal links are omitted where evidence was unavailable.

Main entry points: main.c Game Entry · audio_thread_manager.c Audio Scheduling · z_en_wallmas.c Wallmaster Actor · z_kaleido_manager.c Menus and HUD
