My 2DS R Button is stuck since last month, I desoldered the button and it still always pressed (I really dunno have a clue about what's the cause/how the hell is it possible, but anyway...). Someone know if is possible to disable a button directly on firmware? Like intercept each button press coming from anywhere and nullifying then. And also if is possible to make a trigger to catch a combination like "L+A" and translate to R, to repair it's functionality partially. Well, thanks for any help.
