Z80.NET Release Notes
---------------------
* v1.0.6
- FIX: memory access events were not fired when reading the address of the code to execute
when servicing an interrupt in IM2 mode.
- Z80ProcessorExtensions class removed, its methods are now part of (I)Z80Processor.
- Cleanup of some residual usages of Inc, Dec, Add, Sub from the NumberUtils class.
* v1.0.5
- FIX: ExecuteRet was causing IndexOutOfRangeException when invoked with SP=FFFFh.
* v1.0.4
- FIX: Conditional RET instructions were causing execution to terminate when
AutoStopOnRetWithStackEmpty was set, even when the condition was not met.
* v1.0.3
- REFACTOR: There were some helper methods in place to deal with 8 and 16 bit numbers arithmetic
taking care of overflows and short/ushort conversions. These are not used anymore,
since C# can handle all of this with the built-in arithmetic and casting operators.
They are still used in test code, though.
* v1.0.2
- FIX: Fixed the flags 3 and 5 calculation for the CP instructions.
Now the Z80Processor class passes the ZEXALL test except for the BIT instruction.
- NEW: Z80Processor.ClockSyncrhonizer can now be set to null in order to disable
clock syncrhonization, so that the simulation runs at the maximum speed
provided by the host system.
* v1.0.1
- FIX: Invoking ExecutionStopper.Stop from the BerforeInstructionFetch event
was throwing InstructionFetchFinishedEventNotFiredException.
- FIX: Flags calculation was wrong for ADD, ADC, SUB, SBC, CP, NEG and DAA instructions.
With this fix the Z80Processor class passes the ZEXDOC test
(https://github.com/KnightOS/z80e/blob/master/gpl/zexdoc.src).
