My brother bought Super Smash Bros Brawl a couple of weeks ago, and ever since then the controls have been acting up. The game will interpret a single button press as multiple ones, and it will continuously go in and out of sprint. This has made the game unplayable in the campaign, but when I play against him in versus, the controls are working just fine. I don't know what else to do to fix this, I've tried cleaning the disk, replacing the remote's rechargeable batteries with regular AAs, and updating the Wii. The last thing I can think of is formatting the Wii, which neither me nor my brother want to do. The Wii has been sitting in storage for several months before, and the problem only persists with this game specifically. Is this a glitch, and has anyone else experienced this? And how in the world do I fix it?
UPDATE: During the pause screen, something caught my eye. The game controls would continuously switch between nunchuck mode, and then a different one without the nunchuck. So what I did was I blew any dust out of the nunchuck connector, and the problem lightened up by a little. It was then that I noticed that the connector was loose, and would keep wiggling in and out of the remote. So now the question is how do I fix the nunchuck connector?
