No idea, I'm not a Z80 guy :) However, the CPC core runs in the 1k30,
the smaller of the two FPGAs, and is tuned towards performance and
features rather than 100% compatibility (though it runs the games that
I've tested). If someone was so inclined, they could put a cycle exact
Z80 core with undocumented opcodes in the 1k100 for better compatibi-
lity.
