Apparantly, my parents will make me late for the party. Anyways, I sorta get what you are saying, but in a way I don't. When I first did a code, I did the code I'm trying to do now (get a shiny Ralts), and getting 99 masterballs. It says that the code wouldn't work if I do two at a time. Now, I do the mastercode and the code for the Ralts. But it still doesn't work.
[EDIT]
Okay, this time I'm really leaving. My parents are already starting the car. Bubye, talk to you tomorrow! :classic:
