Hey guys, I love this site!!! You people make children's lives wonderful. I recently encountered a stack dump error problem. I have concluded that bad nunchucks locking themselves in a directional pattern will cause it to crash. Most directly. The illuminated "Afterglow" nunchucks. The plastic semi-sphere under the joystick comes into contact with a computer chip directly under it. They have a small .3 mm indentation but it is not enough and it appears to have gouged the side of the chip away. I unplug the "nun-suck" and everything loads fine!!!! No need to re-format!!!

Hope this helps!!!
