Hi Guys, I bought a new 16GB sdhc for my new 3DSXL, the manual seemed to say I could just pop it into the system. I did; and the system recognized it. This was last week. The blocks are showing up and I haven't seen any issues - however I seem to be reading in various places that I should have formatted it first. Do I need to take it out and format it; or is it fine? Any help would be appreciated.
