Hi, I'm actually making a gamecube portable and I'm having a weird issue with my controller. My controller works fine but after 15-20 seconds it stops working. I don't know from where it can come, I checked my solder, I resoldered all the wires and be very careful. Btw I can't go further than the language selection menu of the gamecube because I don't have any DD, I removed the port and wiating for Megalomaniac to get a wasp and a megadrive. Can it comes from the controller itself? Should I buy a new one? Thanks
