Hey guys. My new 3ds is set up with... reinand? I believe. I use a gate way card i think. Someone helped me by walking me through step by step so I'm not as knowledgeable as i should be. I know i used a regular micro sd card instead of buying a pre-made one offline, at least. Anyway, that's working absolutely fine. However there are a bunch of ds games i want to play as well. I was told i needed to get a flash card. The thing I'm confused about is that i don't know if using a flash card will somehow screw up the set up i have now. Would i just switch out the memory card with the flash card when i wanted to play ds games? Any clarification would be greatly appreciated!
