Internally, this software is made using C++ and WinAPI : both can be easily embedded inside a C# application. As a consequence, I decided to integrate the emulator as a plugin directly into Phactory.
So now once the final DSK file is built, it can be immediately launched under emulator, saving some precious time in the process of adding code / quick testing / adding back other code / etc.
PC-CPC usage is currently optional, there is an option in Phactory to revert back to external launch of WinAPE if required.
I still don't know where this emulator integration will end - Demoniak is currently adding new appreciated debugging features inside the emulator, so I wonder if these additional floating dialogs should be embedded as panels inside Phactory or let them untouched... more information about Phactory can be found here.
