gsword WIP:

Browse Source 
* Split out gsword and josvolly functionalit from base driver class
* Hooked up josvolly MCUs for communication between CPUs
* Added DIP locations to josvolly based on test mode
* Named unknown DIP settings after the location they control in main RAM
* Hooked up josvolly MCUs for communication, still preliminary
* Marked josvolly NOT_WORKING, simulation still present for reference

(nw) The MCU code only makes sense if there are a pair of them hooked up
together.  There are effectively two programs, selected by whether P27
is tied high (master) or low (slave) at reset.  Master and slave have
all corresponding P1 lines connected, master P20 connects to slave
TEST0, and master P21 connects to slave TEST1.  You can see commands
and responses pass between the master and slave, it's very chatty.  Test
mode seems to work, but game mode fails a check after a couple of
seconds and dumps status codes on the screen.  There's still something
missing in the MCU hookup, and I'd guess there's something attached to
the AY output ports, too.
