Static recompilation of Majora's Mask (and soon Ocarina of Time) for PC (Windows/Linux) - Zelda64Recomp/Zelda64Recomp
Zelda 64: Recompiled is a project that uses N64: Recompiled to statically recompile Majora's Mask into a native port with many new features and enhancements.
This doesn't contain the game code either. It takes a user-supplied ROM and converts it to an executable.
Nintendo do not own the code that performs the conversion.
