With all pupnik.de links broken and no hope about RubyBox supporting N770 2007HE... Could somebody share this "mapper.txt" with me? Or point me where to find a working one that enables fullscreen toggle. Please. There is also many post about optimized dosbox.conf. Could somebody share one of them? EDIT: About Addison keyboards, I have no "/usr/bin/dosboxkbd" and if I create one with the xkbd command it does not work, I still have the classic layout. Where I can edit the dosbox xkbd command call?
