Root Directory
In the root directory there are three entries which are of relevance to the PSP. The first is the file memstick.ind which just seems to be
a indication that the stick is formatted (it is not specific to the PSP). The second is the directory psp which contains subdirectories for
the different types of data used by the PSP. These are game, music, photo, and savedata. Not all subdirectories may exist if no data of
the corresponding type is stored. The contents of the subdirectories are detailed in the following sections. In addition, there may be a
mp_root directory in the root. This directory is for storing video, and should contain only a subdirectory called 100mnv01. See the final
section on this page for more information.
22.1.1
PSP Subdirectory
22.1.1.1
Game Subdirectory
The game directory is for PSP software to be run directly from the memory stick. The Files are in
PBP format (see Fileformats Section)
22.1.1.2
Music Subdirectory
The music directory contains audio tracks for the music player. MPEG layer 3 files can be used as
long as their filenames end with ".mp3". ID3 tags are supported and will be displayed by the player. It is possible to create subdirectories
to put the tracks in, but only one level of subdirectories is supported.
22.1.1.3
Photo Subdirectory
This directory contains picture files that can be viewed in the photo viewer. The files should be in
JPEG format, and the filenames should end with ".jpg". Like with the music directory, one level of subdirectories is possible.
22.1.1.4
Savedata Subdirectory
This is where the data saved by games goes. Each game creates a subdirectory with the product
code of the game (e.g. ILJS00002) to get a private namespace, and then adds the following files to it:
ICON0.PNG
A still picture icon in PNG format (24 bits per pixel, 144Œ80 pixels (standard); 300x170 (maximum))
ICON1.PMF
An animated version of the same icon, file format currently unknown. (Optional.)
PIC1.PNG
A full-screen background picture for the file manager in PNG format (24 bits per pixel, 480Œ272 pixels) (Optional.)
SND0.AT3
Background music to play in the file manager, ATRAC3plus encoded in a WAV file. (Optional.) must not be larger than 500kb,
and not longer than 55 seconds.
