The shoulder buttons on the DS and DSi are prone to breaking down from dust and dirt collecting underneath them. You can try cleaning them out yourself by gently lifting the button up and blowing into is or by reaching underneath with a sharp object. If this doesn't fix any issues with the button or you're not comfortable with trying this, you must send your console in for repair.
My L button doesn't work either. I don't know how to fix it, but a specialist will have to do the job.
Put your mouth really close to the R button and blow hard. It really works, I fixed my button that way. If that doesn't work,send your DSi away to Nintendo and they should be able to fix it.
i really need to know
It is the right-hand 'shoulder' button.
try to blow in the DSi around the butten, for this use pressed air NOT your mouth.
Press the power button and the A button at the same time.
yes they can
sorry mate. you'll have to send it off to Nintendo
that's easy all you do and im not kidding it worked on mine is you cover each button one by one with your mouth and blow. its just like an old nes game. i don't know how it does it but it does. note you will have to do it again at times
The WPS button is something on your router, not the DSi itself. It is telling you to press that button (if it has one, not all do) and the DSi will await a signal it will send.
you take the r butten off and you r done or you can take it to a perfesonal
When you are in the Nintendo DSi Menu, Press either L or R to take a picture or Go into Nintendo DSi Camera and tap the button on the touch screen that shows Take Picture.
