I'm currently updating my windows 7 to windows 10. I use the Drastic app to play HeartGold Rom and White 2 Rom and us you can imagine, I want to transfer my pokemon from HeartGold rom and White rom. I tried using pokegen to do that, but for some reason it didn't let me save the file anywhere. Now that I'm gonna use Windows 10, what do you suggest in order to transfer my pokemon. PkHex from now on?
