I bought a new DSi on my trip to Hong Kong, and 3 weeks later, the R button is only responding about 1 out of every 4 times I click it. How should I go about trying to fix this? I speak no Japanese, so I don't know if the warranty covers me (I live in the US). Does anyone have any information on this and how and where I'd send it in if I'm covered? Also, if the warranty doesn't cover me, can someone point me in the right direction for repairing this problem? It kind of makes games, especially ones in the Castlevania series, unplayable. Any help is greatly appreciated. Thanks in advance! after some googling i found out about the blowing trick (wrap lips around the button and blow). This worked really well and my R-button is back to normal. Is this just a temporary fix, or will it eventually break altogether?
