I'm purchasing a 2ds, but need some answers. 1.) Can I run Roms without a flash card? 2.) Will a 3ds hack work on a 2ds, or are they different firmwares? 3.) What firmware will it come with? 4.) If I hack it, will I need a flashcard? Thanks so much! I never got into Nintendo hacking as its just so advanced. I'm good at the ps3 scene and PC.
