    NEC V20/V30/V33 emulator

    (Re)Written June-September 2000 by Bryan McPhail (mish@tendril.co.uk) based
    on code by Oliver Bergmann (Raul_Bloodworth@hotmail.com) who based code
    on the i286 emulator by Fabrice Frances which had initial work based on
    David Hedley's pcemu(!).

    This new core features 99% accurate cycle counts for each processor,
    there are still some complex situations where cycle counts are wrong,
    typically where a few instructions have differing counts for odd/even
    source and odd/even destination memory operands.

    Flag settings are also correct for the NEC processors rather than the
    I86 versions.

    Changelist:

    22/02/2003:
        Removed cycle counts from memory accesses - they are certainly wrong,
        and there is already a memory access cycle penalty in the opcodes
        using them.

        Fixed save states.

        Fixed ADJBA/ADJBS/ADJ4A/ADJ4S flags/return values for all situations.
        (Fixes bugs in Geostorm and Thunderblaster)

        Fixed carry flag on NEG (I thought this had been fixed circa Mame 0.58,
        but it seems I never actually submitted the fix).

        Fixed many cycle counts in instructions and bug in cycle count
        macros (odd word cases were testing for odd instruction word address
        not data address).

    Todo!
        Double check cycle timing is 100%.
        Fix memory interface (should be 16 bit).
