I just realized, it's working ☺️. Somehow I just need to press the hk longer in mupen than on other emulators.

It's only select that doesn't work, as you might have the hotkey on it. We are working on that issue.

I’ve played to Mario Paper about 30min during my tests, and I haven’t had slow down problems.

me too no problem, no slow

hi, in the recalbox.conf file : ## Emulator special keys ## default -> default all special keys ## nomenu -> cannot popup the emulator menu ## none -> no special keys in emulators system.emulators.specialkey=default nomenu for disable the retroarch menu (hotkey B) none for disable all hotkeys (including save / reload etc...)
