What you might want to do straight away is to reverse the O and X buttons, as by default the X button is cancel and O is action which is backwards for most of us. You can do it by going into the in-game menu system and going into "Config", then set the button layout to "Customize" and press right on the D-Pad then just move up/down and press a button for what you want, in this case just reverse X and O.
Assuming you want too of course, such as me I'm too used to have X for action and O for cancel.
