NetBattles with Navis
If you didn't know already you first battle a Navi for the story. Next time you fight the navi it is the same navi, no SP or EX. When you beat them again you get the normal chip. Next time you battle them the will be in EX form and when you win you get the EX battlechip. The next form is SP and in order to get the SP chip you have to get a high ranking. If not you only get the normal chip. From then on you always fight the SP version... Well to my knowledge you do... You will also keep record of your fastest delete time for SP navis.
