checked-yes =>Quick Switch: If you hold Z+[START] you will bring up the "Switch Game Pak" option without needing to go through the system menu. =>One Handed Controls: If you set the control option so that X and Y work as the [L] and [R] buttons, the C stick will become active, allowing you to use it as if it were the control pad. This means you can access all the GBA buttons using just your right hand.
