Emulating more instructions, up to 0xBNNN. Fairly boring, but necessary.
I also get confused over being unable to read, as is tradition.

Errata:
- I thought setting VF/carry flag before computations was OK, but that is not true if VF itself is used in the computations, and maybe in other cases. There will be an "extra" part after part 5 (the original ending...) as I found a better test rom and will rectify these mistakes then.
