Hi.
My GBA's R button mechanism seems to have stopped working. It's not the plastic button, it's the thing on the motherboard. I've tried cleaning it with isopropyl alcohol and q-tips and blowing on it but it hasn't worked. I thought it would be the R button itself but after that I now know it's the mechanism itself. I think I'm going to have to get a replacement R mechanism and desolder and resolder the trigger back on. Any easier way that this can get fixed?
