I'm not sure if that is true, some of the undocumented opcodes rely on analogue side effects of the digital circuits and so a pure translation of the netlist is not going to implement them correctly. You'd need to start emulating the analogue behavior. Though I'm not sure that all undocumented opcodes are actually that important.
