Z80 Instruction Exerciser

From: https://mdfs.net/Software/Z80/Exerciser/


Frank Cringle's Z80 instruction set exerciser attempts to execute every Z80
opcode, putting them through a cycle of tests and comparing the results to
actual results from running the code on a real Z80. The exerciser is supplied
with Frank's YAZE (Yet Another Z80 Emulator). It is often difficult to track
down, so I have put it together here, as well as some conversions. The latest
release of YAZE is available at Andreas Gerlich's website.

ZEXDOC only tests officially documented flag effects, whereas ZEXALL tests all
flags changes, compared against test on real hardware. ZEXALL and ZEXDOC are
released under the GNU General Public License.
