How come Nintendo System have some problem with their system like GBA, GBA micro, DS lite and DSi have fault issue like system problem like a hinge on the DS and busted L trigger on DS lite, DSi and GBA micro? I trying to fix this problem right now. I figure it out it the Left control pad sensor is not working. What should I do? It totally useless now that I can't use the control pad on my GBA micro.
