I think there may be some way to test whether or not Dolphin is accepting the input properly, so meddle around with settings until you know it is working properly. Hopefully you'll encounter something you know is wrong and will fix it. Also perseverance helps. Sometimes doing the same thing 10 times in a row will suddenly work.
