Just explain the general layout of your SD card. No need to include everything, just give a general idea. The root of my cart consists of two (unhidden) folders. One is titled "Emulators/GBA" where I keep my emulators, and inside of that folder is a folder called "GBA" where I keep all my GBA roms. All of the roms for my emulators are in hidden folders on my root. My other visible folder is titled, "Homebrew, etc" where I just have homebrew games and applications. Nothing special. Moonshel is in the normal place (I'm using a cyclo, so I don't have to worry about that). All of my NDS roms are on my root, so once you scroll past the first two folders, you can see all my my NDS games. I'm tempted to make a NDS folder, but idk.
