I'm a complete beginner in doing anything with flashcards. All I know currently are the following: I have a Midnight Purple 3DS, it's firmware is 4.0.3-01u (Just bought it today.) The only flashcard I could find that works with this firmware currently is a: R4i Gold 3DS I have no idea where any trusted sites would be to buy one from. (I'm in the US, I really don't want to pay/wait for China to US shipping.) All in all, just throw links at me and I'll figure it out, Googling these things didn't help, just thread after thread after thread. Thanks in advance!
