Nintendo has released a new 3DS patch for Mario Kart 7. It fixes a major glitch that was found in Maka wuhu, where racers online skip half of the course and get a huge advantage over the other players. This has been a major problem with many players around the world right now for those who don't know how to do it. Because of that, All Mario Kart 7 owners must update before they can play online. It's now available in the Nintendo eShop.
"In order to use online services, a newer version od this software is required. Download the newest version of this software from the Nintendo eShop or other supported software" ~Nintendo
Update: The patch also includes exploit fixes in Wuhu Loop and GBA Bowser Castle. (thanks to the Anonymous comment for bringing it up)
