/* Alignment of HSYNC Interrupt */
In fact the only difference between T80 of opencore and real Z80 is that T80 run on rising_edge, and Z80 run during low state. Test past with little modification of sequencer forcing it do nothing during low state of z80, resulting a downclock (memory is too overclocked with this sequencer modification), perhaps using buffer on address bus and data bus could solve this detail... but as it runs for me it is not a problem.
