*
* Changes in 3.2
* - Fixed undocumented flags XF & YF of RRCA, and CF and HF of
* INI/IND/OUTI/OUTD/INIR/INDR/OTIR/OTDR [Sean Young]
* Changes in 3.1
* - removed the REPEAT_AT_ONCE execution of LDIR/CPIR etc. opcodes
* for readabilities sake and because the implementation was buggy
* (and I was not able to find the difference)
* Changes in 3.0
* - 'finished' switch to dynamically overrideable cycle count tables
* Changes in 2.9:
* - added methods to access and override the cycle count tables
* - fixed handling and timing of multiple DD/FD prefixed opcodes
* Changes in 2.8:
* - OUTI/OUTD/OTIR/OTDR also pre-decrement the B register now.
* This was wrong because of a bug fix on the wrong side
* (astrocade sound driver).
* Changes in 2.7:
* - removed z80_vm specific code, it's not needed (and never was).
* Changes in 2.6:
* - BUSY_LOOP_HACKS needed to call change_pc16() earlier, before
* checking the opcodes at the new address, because otherwise they
* might access the old (wrong or even NULL) banked memory region.
* Thanks to Sean Young for finding this nasty bug.
* Changes in 2.5:
* - Burning cycles always adjusts the ICount by a multiple of 4.
* - In REPEAT_AT_ONCE cases the R register wasn't incremented twice
* per repetition as it should have been. Those repeated opcodes
* could also underflow the ICount.
* - Simplified TIME_LOOP_HACKS for BC and added two more for DE + HL
* timing loops. I think those hacks weren't endian safe before too.
* Changes in 2.4:
* - z80_reset zaps the entire context, sets IX and IY to 0xffff(!) and
* sets the Z flag. With these changes the Tehkan World Cup driver
* _seems_ to work again.
* Changes in 2.3:
* - External termination of the execution loop calls z80_burn() and
* z80_vm_burn() to burn an amount of cycles (R adjustment)
* - Shortcuts which burn CPU cycles (BUSY_LOOP_HACKS and TIME_LOOP_HACKS)
* now also adjust the R register depending on the skipped opcodes.
* Changes in 2.2:
* - Fixed bugs in CPL, SCF and CCF instructions flag handling.
* - Changed variable EA and ARG16() function to UINT32; this
* produces slightly more efficient code.
* - The DD/FD XY CB opcodes where XY is 40-7F and Y is not 6/E
* are changed to calls to the X6/XE opcodes to reduce object size.
* They're hardly ever used so this should not yield a speed penalty.
* New in 2.0:
* - Optional more exact Z80 emulation (#define Z80_EXACT 1) according
* to a detailed description by Sean Young which can be found at:
* http://www.msxnet.org/tech/Z80/z80undoc.txt
