Z80test fails

Haroldo64 opened this issue · comments

Hi, some z80 cpu tests fail

z80test-1.0.zip

as I see pair test failed for processing of undocumented flags, I saw it before but still have no idea how to fix, I have added some tests but without success

hi, could you see the source from Fuse ? It passes all z80 tests:

Untitled 2

Yes, I have checked them on fuse and on fuse they work.
Something to be implemented in z80 core emulation

May these Z80 core files be useful ?

zilogz80.zip

Z80 instructions and CCF/SCF XY and others flags aren't fully implemented, if it could be possible to use "fuse cpu source code" it would be better because it works well.

I use latest Z80 test from FUSE and it shows that I have only problem with F3/F5 with BIT n, (HL)

Hi, any news for a new release ?

@Haroldo64
if you about Z80 core incompatibility then there no news yet, I still can't find place where undocumented flags unexpectedly changed

I have fixed Z80 core and now all tests passed like in Fuse
