Unless you are some obsessive freak, you will not want to watch the credits for five minutes everytime you beat the "Elite" Four (except maybe the first time just to check it out). Well, if you notice that just before your pokemon are entered, the screen will say "Saving, don't turn off the power". So, after it does that (I usually wait until it shows all six guys just in case) turn the game off and then back on, or reset it, whichever takes your fancy. When you turn the game back on or it finishes reseting, you will be back and Pallet Town, with five minutes to spare.
