Ocarina of Time: an early ROM disassembly and NTSC 1.0 memory map

zelda_oot assembles an Ocarina of Time ROM from game assembly and files extracted from a base ROM. Its Makefile checks the resulting image against an MD5 checksum, while included NTSC 1.0 notes map save data, inventory fields, and instruction addresses.
