To be honest i cant think off any games where 7 or 8 buttons would be used except for Defender, i use buttons for this as i find it easier than a joystick, so for me it : up,down, thrust,fire,reverse, smart bomb and hyperspace. but also in saying that when not in MaMe the buttons also double as navigation for GameEx for example my right flipper button is fwd in GameEx and volume up in jukebox.
