If your Action Replay still doesn't work I suggest you buy a new one.

yo i know exactly what to do
you know how there is that one code that is the (M) code... well it needs to be in there and it cant be in a folder. i dont know what the code is but you know that your action replay will work when it says that there is 1 code already activated in the action replays start screen so if you dont have the (M) code by its self and on your action replay it wont work

how to reset the Action Replay DS OK we have finally done it!! YEAGH!. Here is the trick for those like my son and I that are trying to get the darn thing to reset. All you have to do is Hold down A&B first while the unit is off. Keep holding A&B buttons then be ready to press the Start & Select button just after you turn on the DS. Wait for the White screen to Appear after bootup, then press and hold the Start & Select buttons while still remaining to hold the A&B Buttons, before the words appear. Another words after health and saftey screen a white screen will appear that is when you add the start & select buttons along with the A&B Buttons. The white screen will stay on for 10 seconds. If it does not stay on the white screen foe about 10 Seconds, it did not work. Otherwise ours did not work until we jumpped the gun on the Liscense screen. Hope this helps someone. :)
