Couldn't find anything about this, so maybe it's not a common problem. All but the first controller port has suddenly stopped working, all at the same time. I just bought one of the Nyko wireless controllers and plugged in the reciever to the second port and left it there for about a day. I doubt it's related since destroying the system seems like a serious enough design flaw for QA to have mentioned. Neither the wireless or the original will work in any port saving the first, nor will the GBA link cable. The game will prompt me to plug in the cable even after I have done so.

Anyone got any suggestions? Hopefully it's just something stupid that I can fix rather than my system being completely hosed.
