Pokemon X & Y has received a mandatory 1.2 update that is necessary for online play. Sources suggest that the patch nukes an exploit that let players view their opponent’s team before starting a match.
Serebii reports that the update requires 236 blocks on your console and will reactivate Rating Battles after Game Freak took them offline once the breach was discovered.
You’ll find the update on Nintendo’s eShop now.
