# n64dd: decompiling Ocarina of Time's Disk Drive code

> n64dd reconstructs the Nintendo 64 Disk Drive component found in an Ocarina of Time ROM as C and assembly. Its scripts extract a user-supplied NTSC US ROM, produce disassembly and build the component; the Makefile provides an MD5 comparison mode for output.
