Thanks for the replies guys

. Have any of you guys gone from straight to curved and then regreted it? Thinking about the number of buttons, I may go with 3 per player now. Would this cater for most of the old games? Are there many that use 4+ that are not fighters?

EDIT: Does anybody know of any files that I can use in Mame32 that show the number of buttons used per game? I have seen one for players.
