Case study

Metroid: byte-matched NES disassembly

This disassembles Metroid for the NES. The ROM has eight 16 KB banks. Banks 00 through 06 swap into lower memory, and bank 07 stays in upper memory. The included build script assembles the banks with Ophis and compares each output MD5 with the original binaries.
