Great emulator, but I've run into a problem. I have a nexus 7 with stock ROM. I tried plugging in my ps3 controller via OTG . This setup works fine with dead trigger and a few other emulators....unfortunately not with fpse ... All it does is control the menu.... I try to map the buttons and it seems to go through but when I boot up game its not working .....triangle brings up menu and start seems to act as back button..... Any ideas how I can make this work??
