-Found a few more fixeight opcodes, by matching code in the interrupt routines with batsugun [Alex Jackson]
-Corrected fixeight V25 address map (the YM2151 and OKI6295 are at a different location than the other games) [Alex Jackson]
-Preliminary implementation of V25/V35 port output [Alex Jackson]

Interrupt macro service function not implemented.
Port implementation is incomplete: only input works
for now, and mode control registers are ignored.
Port implementation is incomplete: mode control registers are ignored.
Timer implementation is crude and incomplete.
Timer implementation is incomplete: polling is not implemented
(reading any of the registers just returns the last value written)
Serial interface and DMA functions not implemented.
Note that these functions differ considerably between
