Hello. I was just wondering if anyone can point me in the right direction. I've ordered a nintendo 3ds that supposedly comes with 4.2E/4.5E firmware. I want to be able to play roms specifically Pokemon platinum, pokemon black and white and majoras mask. Is there a way for me to currently be able to do this without paying for a flashcart? I don't mind cfw. If so could someone point me in the right direction to a guide and what will I need. Many thanks for your help.
