In fact the only difference between [[T80]] of opencore and real Z80 is that [[T80]] runs on rising_edge, and Z80 runs during low state. Test past with little modification of sequencer forcing it to 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.

Problem here : CPDR and CPIR has same implementation than CPD and CPI.
