My cabinet is an old Street Fighter II. So it just has the two sticks, and 6 buttons per player, and the 1 & 2 starts.. So to me, the most intuitive way to control it seems to be using the stick to move focus. I thought about the idea of assigning a button to be "A", "B", etc., but the problem with that is people that are unfamiliar with the machine won't know what is what. I'm not going to make a new CPO to add stuff just for the jukebox, it's kind of just an "extra".
