for better or worse I've got the layout I am going with. The center lines are drawn an are 3 inches and 4 5/8 inches for reference. The joystick is 2 1/2 inches from each side. It is slightly biased toward the player since 3 inches is the center line. The two action buttons are 1 1/2 inches and 3 and 1/4 inches from the side. It will also sit on the 2 and 1/2 inch line as the joystick does. The start button is set in between the two action buttons and 1 and 1/2 inches from the back.
Hopefully this works because once I punch holes it is over, heh heh
Thanks,
Stephen
