An exploit found in the Wuhu Mountain Loop course of Mario Kart 7 which makes it possible to skip around half of the course is to be left untouched, Nintendo has confirmed to Sticktwiddlers.

The glitch makes it possible for racers to drive off of the track at a specific point, to be returned to the track much further on. Those using the exploit are gaining an unassailable advantage when racing online against players unaware of the cheat.

However, Nintendo feels it would be unfair to update the game to remove the exploit.

"We are aware that it is possible to navigate a certain part of the track in Wuhu Island in a way that allows a large part of the course to be bypassed," said Nintendo spokesman Buddy Roemer.

"There are no plans to update the game to remove this shortcut as doing so would create an unfair advantage for the users of the original release of the game. Rest assured your comments have been added to our records for Mario Kart 7."

Mario Kart 7 does, however, remain one of the must-have titles for the 3DS, earning a deserved 9/10 in our review.

It looks like players are just going to have to accept that the exploit exists, hopefully telling competitors whether the cheat will be used in a race.

It's also interesting that Nintendo talks about creating an unfair advantage to players of the original game, suggesting it would have to release a new version of the game in order to fix the exploit. Does this mean that 3DS games don't support the patching process?
