I have compiled the Chips version of uae4all2 and now have a second Amiga menu in EmulationStation where I can automatically launch adf / adz files by using the df0 command line parameter and not going via the uae4all2 GUI at all. This works great for games with only one floppy drive (for example I have large number of coverdisks and public domain games, and older games).
How do I quit the emulator though? LCtrl + Esc doesn’t work. Neither does any other sensible keyboard combination that I tried
