@holmes Sorry, but unfortunately there is no workaround at the moment, the developers are working on a fix that will be made available in the next version, which should be released soon (but doesn't have a release date yet).
Did you try to switch snes emulator with your recalbox.conf file ? (this recalbox.conf version is for the 3.3.0 beta and this one for the 3.2.11) Try with snes9x core.
