Yes, you will, unless you have another Pokemon version like diamond, pearl, or heartgold. If you do, use another DS (a friend's another family member's) to trade over all the Pokemon that are important to you. Then, after you do this, restart the game.

hold L R Start and Select I keep trying that, all that happens is that the screen goes white, and then I have to restart the game any more suggestions?
Impossible!
by restart? new game on the main menu? or if you mean soft reset, L+R+Start+Select. I try to reset using the buttons, L+R+Start+Select, all that happens is I have to rebegin the game from where I last saved. Presently I am playing Soulsilver, but I also own Heartgold as well. How can I refresh my screen, without having to rebegin from where I last saved?
heartgold & soulsilver.
finish the game
