# Ocarina of Time 3D: a hash-checked 3DS decompilation

> Ocarina of Time 3D reconstructs source for the USA release of The Legend of Zelda: Ocarina of Time 3D through static and dynamic analysis. Its Windows build produces oot3d.axf and code.bin, with an MD5-based matching check; rebuilding romfs.bin and the full 3DS image remains future work.
