My DS lite is having some R button issues. It works probably around 1/20 times but I have to press down REALLY hard. This has happened to me before (with a launch phat ds) except it was with both L and R. I tried to fix it then and replace the case, but I had no idea what I was doing and the only guide I could find online was a spanish one and now my launch phat ds is in pieces[yeah, I still have them]). I'm wondering, since the problem is probably being caused by the spring, should I open it up and fix it? I don't want to lose this ds too. Is there a way where I can check if the problem is the spring or not without opening it up? Thanks in advance.
