Mario Kart DS Glitches

Arrows to Boxes?
You first need an action replay with the unlimited golden mushroom code (listed below) enabled. Then go into time trials and choose ANY track you want. As soon as the race starts press the L button rapidly then look on the touch screen and the little arrows will eventually dissapear. Wait a few seconds WHILE YOUR STILL PRESSING L and then you'll see boxes appear instead of little arrows!

Press L for Golden mushrooms
