This spec can be used to disassemble raw stream of 6502 CPU machine
code into individual operations. Each operation includes an opcode
and, optionally, an argument. Register arguments are part of the
opcode enum.
This page hosts a formal specification of code_6502 using Kaitai Struct. This specification can be automatically translated into a variety of programming languages to get a parsing library.
