Hrm. you can only do even/odd parity if you have 7 bits for the data bit.
(I think anyway...  I've never attempted it.)

Thanks for letting me know it works ;)
If you can think of any improvements just let me know...

Yes, those percent signs get annoying after a while.
Maybe someone could come up with some macros in an include file
that could make inline assembly very simple, where the macros would
translate to the proper inline assembly syntax.  Although it's not really
_too_ tough to figure out.

Sure, I'd love to take a look at it.  Is there a single player mode?
