How do you add code or get the codes to work??? I've added codes from the internet, and it doesn't work at all. There's like 4-5 extra zeros at the end of each code and you can't delete them?? Does this sound right? I'm trying to use it on Leaf Green, Fire Red, and Ruby. Exact same one I have here: I'm sure someone seen this before at least got to have one. Help me!!!
