Hi, i have a R4 cart, with save files for both pokemon pearl, and pokemon white. I want to be able to transfer my pokemon from pearl to white, and i don't know how to do this, whether i will need 2 emulators, or emulators with wifi, or wireless capabilities... on the actual ds it is done though wireless communication to a second ds, but how can i make this work on an emulator, and which emulator(s) would best do the job?? Thanks very much Megan
