Nintendo 3DS SD card filesystem

Here's a page describing the SD card filesystem used by the Nintendo 3DS. (I found this because my son's SD card was corrupted, to much wailing and gnashing of teeth - unfortunately, Nintendo is kind enough to have encrypted everything on the SD card using a 2048-bit AES cypher, so I can't really do anything to restore his Fire Emblem characters.)

This, again, is an interesting instance of "how to recognize information in data". Just filed for later reference.
