I recently hooked up buttons 5 and 6 to my jpac, I then configured those buttons via mame so it would register.  I decided to test it out on a game and turned out perfect.  Now the problem my FE is arcade maximus and no matter what I do I cant get maximus arcade to detect button 5 and 6 when playing a game.  I rechecked mame directly and it works but anytime I pick a game through the FE button 5 and 6 wont work!  Any ideas?
