Thinking the external mic was broke. I sent my DS Lite into nintendo to get the Mic repaired. its back but the external mic doesn't work with my games on my EZFV 3in1. I don't know if it works on retail games because I don't have a game that uses the mic. however it does work with the headset. Any clues? Is there a setting to turn the external mic off anywhere? Should I call Nintendo or go and buy a game that uses the mic? Thanks for reading this! I wish i had another DS around to check this with the cart I have.
