Oops, after reading my post, I realized why everyone only answered my trackball question. My original intent was to ask:
How many buttons do I need for trackball games? I've seen control panels with three buttons above the trackball...
How many buttons do I need for 4-way joystick games? I've seen two buttons usually.
How many buttons do I need for spinner games?
How many buttons do I need for top-fire games?
Also, if I need x buttons for a certain joystick, do you suggest I try to manipulate the console configuration so that I take advantage of using other buttons such as the player1 button as suggested.
Finally, I'm designing the configuration using Visio, but I was looking at some of the NEAT console overlays that people have made. I was just wondering if they use visio for this, or is it better to export the visio project into something let's say Illustrator can read.
Btw, I totally appreciate all the helpful suggestions I've gotten on this board. Being all the way out here in Hawai`i, nobody does these kinds of things and without you guys, this project of mine would be non-existent.
Mahalo,
Ryan
