How does everyone label the buttons on their CP? For me I am going to install 4 buttons (plus 3 others for 1/2 player and coin) for the classic games I play and these will map to the shift, control, spacebar, and alt key.
What is the standard mechinism to label these buttons so that others can tell which is needed for a game? Do you use 1/2/3/4 or the actual key name or just leave them blank and let everyone guess?
