iv got a bartop setup and when i setup mame exit hotkey to a arcade button it returns to the displays menu but keeps the last mame game running in the background so when i launch another game its running both at same time... it only exits correctly if i use the esc button on keyboard but the key board will not be accessible all the time... im using floobs v05 all updated with pi3 and Xin Mo Controllers (arcade buttons) i ahve serched everywhere and cannot find a fix for this
