Possible bug in handy/handybug (0.95)

"stz" does not modify the Z bit => correct handled.

But after "stz" the "beq" is not emultated correctly, as if the Z bit was negated.

 

But I have'nt yet made a real test case.

 

Edit: *hmpf* I cannot reproduce the issue :( (or better :-), since we do not want a bug in handy)

STZ seems to reset the Z flag (and not set it, which is correct at least) in your example.

However, I do not see it in my version Handy GCC/SDL Portable Atari Lynx Emulator v0.5
Based upon Handy 0.95 WIN32 by Keith Wilkins.

This works as expected, also with other addresses for STZ.
