The version v0.37.0 of Xcpc has been released !

What’s new ?

This version includes the new Z80 emulation engine. The Z80 cpu emulator has completely been rewritten and contains no external code anymore.

This new Z80 kernel supports all documented and undocumented instructions and flags. It passes all (but one really minor) tests of the well-known and famous « Z80 instruction exerciser » (Zexdoc and Zexall). Some micro-bugs may be present but a lot of tests have been done. I have not observed any regressions and the cpu emulation seems to be better than ever, so I’m very confident about this new Z80 emulation engine.

A small bug has been fixed in the Gtk+-3.x user interface when lauching multiple instances of Xcpc; the GApplication object class requires only one instance of an application-id so I had to fix the code and connect the internal user-interface builder to the good signals.
