parity instead of overflow
2013-05-08Set PV flag based on parity, not overflow for XORMike Pavone
2013-05-08BIT was setting the zero flag to the opposite of what it should have. This ↵Mike Pavone

2013-05-06Hopefully more correct implementation of the Z80 busack statusMike Pavone
2013-05-05Add a YM2612 stub implementation with just timers and status registers so ↵Mike Pavone
that games that depend on it can run.
