This was very interesting, but is there some kind of formatting failure that prevents the actual instruction definitions (the syntax) from being shown alongside the explanations? Seemed ... oddly confusing. Even if these are undocumented "Black market" instructions, someone must have picked mnemonics?

Nice article! Do you have a board to experiment on or is this all on QEMU? I've been wanting to try one of the Banana Pi boards, but I think it's going to be _quite_ painful
