Recently, I took off my old consoles from their boxes with the intention to do some retro-gaming but found two problems which look alike: my gamecube controller has a problem where it's digital stick seems fixed to a direction (try to play metroid prime with that if you can) and my playstation2 dualshock seems to have broken something since triangle, x and circle doesn't work.
I fixed previously my old supernintendo controllers but since those two look a little more complex so I want some information before breaking them without return
