Copying saves to retail DS carts

I recently started playing Pokemon SoulSilver, and decided that since I love the game so much I want to buy the retail cart to support the devs. However, I've gotten 3 badges and don't really want to start over. Is there any possible way to copy my save to a retail cart after I buy it? I have an Acekard 2 an an Ez Flash 3-in-1 if that matters at all.Thanks!

Well, I thought existing homebrew programs would work. But apparently they don't work with Heart Gold or Soul Silver. I don't know why, the developers must have changed something with the save files on those carts.http://forum.romulation.net/index.php?topic=36479.0
