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.

HNN mulls over directory structures
