I have a Supercard DSTWO and a 3DS XL, I'm gonna buy Pokemon Black 2 for PokeTransporter and I want to know if there's a way to backup/restore save files using a flashcard only, savegame manager ds worked with my DS Lite but I had to give it away, I tried savegame manager but it keeps giving me the same error ''Flash 0KB'' (my guessing its the automatic cartridge detect, so it doesn't allow for hot swapping I guess)
