quick-and-dirty port of my Zymosis Z80 emulation engine to D.
code was built from scratch and not using huge tables to generate
huge sources (it's just one module with source size ~64KB).
it properly emulates all known Z80 quirks (including MEMPTR
register) and passes all 1335 tests from

sorry, it uses GDC @attribute(forceinline) feature, so you
need latest GDC to build it. it's not strictly necessary though
