CALL NINTENDO!!
You'd think they would do nothing to help you, and try to get your $75.00 to fix it...
But I just dropped mine off at an authorized repair center for no charge!
Just a little tip...get a nice guy on the phone, tell him your problem (mine was it couldn't read games correctly), and he might just change your warranty to be longer, so it will be free.
I just wanted to let this be known, so no one (hopefully) will be forced to pay this wretched fee. BTW, I was only like 3 months over my warranty, so it could be different at later times.
