How would I back up cart saves and transfer R4 saves on to the cart? I give up waiting for the R4 to work with Pokemon BR, so I don't wanna waste money buying my own cart... My friend has a US Diamond cart but how would I take the legit save data from his cart and put it on my PC? Then how would I be able to transfer my R4 save data to the cart? Finaly - what would I have to do to overwrite his save on mine on the cart when I'm done? Thanks , sorry for sounding so confusing :/. All I have is the R4 and the cart, by the way. Do I need more?
