Nintendo has deployed its promised patch for Mario Kart 7. It eliminates the ability to skip large sections of the race track on specific courses.
Fair online racing was previously made impossible by cheaters deliberately exploiting the game's glitches and repeatedly choosing broken levels to play on.
The patch mends the notorious Wuhu Mountain Loop glitch and provides similar fixes for the Wuhu Island Loop and GBA Bowser Castle 1 courses.
