I hope this is the right place for this. I've noticed lately that my gamecube controller doesn't work quite right on some gamecube games on the Wii. Specifically, Lord Of The Rings Two Towers and Lord Of The Rings Return Of The King. If I need the character to go forwards or backwards, I have to press forward or backwards really hard and often times at a slight angle before I get to straight forwards or straight backwards. Left and right seem to work just fine. But it's strange. As far as I can tell, the controller only works like this for these two games. It seems to work just fine for other gamecube games like Metroid Prime, Spiderman The Movie, and others. Any idea of what's wrong ?
