I bought a plain (non-special-edition) Nintendo 3DS XL, turned it on, and followed the initial setup instructions. Once it was all set up, I removed the preinstalled SD card and inserted a fresh 32GB card I purchased for this purpose.
It wasn't until nearly 24 hours worth of play time later that I discovered (by putting it in my computer) that the original SD card had data on it, in the
Nintendo 3DS folder. More than 20MB worth.
Now, I didn't download any games prior to swapping cards, I finished the initial setup (connect to Wifi, etc.) and immediately powered it off and replaced the card.
So what am I missing? What data comes on the preinstalled SD card?
