Yeah mine did that to.
Now to fix it you may lose all of your codes but your Ar recognizes your game.
1. Get the code for your game. Its written under unknown game.
2. write that code down somewhere and turn off the council. (The whole game)
3. remove the game but insert the Action replay. And go to add new game or something of the like. the button you use to add codes takes you there.
4. punch in the game code that you wrote down in step 1. after punching in the name of the game.
5. once it is added to the game list shut off council again.
6. reinsert game disk and action replay. It should recognize your game now.
7.your codes are gone. which sucks. (or maybe its because I messed it up to the point that i reset my code list) I reccommend finding and copy/pasting the codes you had in a word doccument of some form and saving in the computer as you go just in case. E-mail it to yourself so you can acess the saved codes anywhere. sorry for the inconvenience. when mine went out i tried to fix it with the game was in the AR and all I got were blue/red stripes pulling a freaky. Thats why its hard to fix. The manuel is vauge around troubleshooting.
Sorry for your troubles have a nice day.
