A Z80 test-program for ZX Spectrum Computer can be found under:
https://github.com/raxoft/z80test
which performs 152 Tests on Z80-Emulation.
MAME 0.227 fails on two of these tests, as can be read here:

Maybe someone from the MAMEDEV-Team want to look, why those tests fail.

Just for completeness, these are the test, where MAME 0.227 fails:
Maybe only a slight problem coming from emulating a Z80 processor from a special manufacturer SCS instead of ZILOG according to:
https://worldofspectrum.org/forums/disc ... scovery/p1
and:

"SCF/CCF flags seems to be a little nightmare on CPUs that are not genuine Zilog."
