I can start by tackling the opcode list. I will do it the same way I did the 65C02 opcodes with the CSV generated list.

I'm working on the 65C816 opcodes sheet now. I'd like to make this Appendix D and push down the "official expansion cards" appendix.

Where should we put the X16 platform-specific considerations stuff? In the same appendix, or should we maybe make that Appendix D and the opcode reference Appendix E?
