I get that you can't use the stick with all games but the R button in the least should work as a replacement for those with a broken R button (IE me). I've been meaning to send mine away to Nintendo to fix the R button but I'm too addicted to Tomodachi Life and Animal Crossing to go without a fix for more than 7 hours.
How am I supposed to Mario Kart? Nintendo, pls. I need my R button.
