Maybe I should put this here instead of in Audio/Jukebox/MP3 forum......

Hey everyone, after finally finishing my basement remodel, I am in the final stages of getting mame setup configured.
One question I have is, do I need to setup button configs for each game I have listed? I see there is a universal button setup, but it seems when I go into a game, the buttons don't work. Now if I load the game and go into the button config section for just that game, the buttons will work fine. I was hoping I could do a global setup so button 1 is button 1 on all games, button 2 is button 2 on all games etc etc. I can't seem to get that part to work....or would I not even want that since different games have different layouts?
Thanks,
Peja
