These days, this is not true anymore. I believe
MESS and MSKISS also pass in all ZEX tests. fMSX-based
emulators do not pass in the tests, since the Z80 core
of fMSX does not emulate undocumented flags.

Well, it's very hard to get it working :)
The algorithm is a CRC on almost all Z80 opcodes,
for a lot (and I mean A LOT) of random-generated input data.
It takes many minutes to run it entirely (IIRC, some hours
on a standard Z80 @ 3.57 MHz).

It's inside the YAZE package:
