Ah, not to say anything negative about your code,
since the number of opcodes is small,
the whole "if -elif" branch (which in a C++ emu would probably be a switch)
is okay because it's concise.
However, in a larger subset of opcodes,
it starts too look ugly and hard to manage.
I know there's a more elegant approach to this,
and I've thought about it a lot.
You have any ideas on this?
the reason I ask is because I'm writing a
CPU emulator that has ~57 opcodes
and 13 addressing modes and
I really don't want a giant if-elif branch.
I don't care if there's a slight speed hit
by making them classes or functions or something.
My goal is to make the code understandable
and pretty, not fast.  I can make it fast later
if I need to.  I'm not going to try to write optimized code
off the bat.
So if you have any idea on how to implement the opcodes
in a less-switchy way, I'd appreciate the input.
Thanks.
