Mario Kart 7 & 3DS Update
People who love playing Mario Kart 7
will know that there are certain shortcuts and exploits that players will abuse while playing the game. Well, now Nintendo has finally released an update that will alleviate the problem. The patch will eliminate the shortcuts in three tracks ("Wuhu Loop," "Maka Wuhu," and "Bowser Castle 1") for people playing the game online. In fact, downloading the patch will be necessary to play the game online beginning May 16 (people can still enjoy the game offline without the patch). People can find the update in the Nintendo eShop. Deleting the patch will require people to redownload it again.
Aside from the Mario Kart 7
update, there is also a surprise 3DS systems update. Update 4.1.0-8 is available now, and aside from the usual "enhancements and behind the scene improvements", this update will allow people to update the the system without the need of entering the pin number if parental controls are enabled.
