I did what the answerWhat if your action replay ds v 1.60 says theres no free space to download a new game on to your action replay when theres nothing there but when it ended loading and it still won?

Answer 1

You corrupted the data on the AR when you turned off the DS while it was trying to write. Now you have to reset the AR. To do that, make sure the AR is connected and the DS is turned off. Hold down A+B and keep holding them down while you turn on the DS. Just before the message that this product is not endorsed by Nintendo, and while still holding down A+B, hold down Start+Select. Keep holding all these down until the Enter Game Card screen comes up. It's tricky to keep all the buttons held down, so you might have to try it a few times before it's really reset. You'll know if it's reset because you'll be able to copy a code over to your AR.
