So, I got a Midnight Purple 3DS from GameStop. I used to have a DS Lite on which I played Pokemon Black. However, I never had an internet account for purchasing any games/Download Play, and have only connected a few times with local DS systems such as my sister and my school friends.
Upon receiving my 3DS, I put in my Black cartridge (this was before inserting any SD Card or my new Omega Ruby cartridge). It worked perfectly fine. I need to know, now that I have both an SD Card and Omega Ruby, whether it would still work. I am considering moving my team to PokeBank and I don't want to mess up any of my save files.
