Hi
-Pentagon emulation is experimental, but I’m trying to do my best I will try that demo
-sna specification is for formats Spectrum 48 and 128, there are no “Pentagon” sna files, as far as I know. But you can change a ZEsarUX setting to tell the emulator not to change the current machine and you could load sna in Pentagon
-drag and drop only works by default in Mac. You can enable it on other machines if you compile from sources and have the SDL2 libraries

-french? Who is speaking french? XD. My text was written in English. And I can also speak Catalan and Spanish. And I just understand a little little bit of Russian and Cyrillic writing
