I was just on my Nintendo 3DS playing on Mario Kart 7 and whenever I stand up playing, it doesn't feel the same as me playing sitting down. There is this glider thing and the keys are really sensitive. Whenever you press B, it cancels out the glider, like I was told on the Mario Kart Wii forums. Well, whenever my character is doing funny stuff, I also must be pressing something wrong like B. So there must be some way to clean the A button if it is so slippery. I also don't want it to be sticky either because the later part comes Kalimari Desert where you must be able to stop whenever the train crosses in front of you sometimes if you fail at the part to go up the ramp and off it, so there must be some sort of alternative to navigating on Mario Kart 7. My regular Nintendo DS's, the one I currently use, NOT the one all messed up feels fine, and the A button doesn't feel slippery at all.
