What does debugging a tamagotchi do?

Im improving it. I just did it myself actually, and it works really well. You take the back off like your going to change the battery. Take out the battery and unscrew the 4 screws at the sides. Split it in half and below the battery you will see a circle and above it will be written debug. Rub it with a led pencil for half a minute and put it back together. Get a new egg and when it hatches keep pressing A to scroll through the characters you want. Press c to go onto hyper speed mode and press c again to stop. In debug mode, you will NOT have access to the internet. Hope i helped!
