The folder will be created automatically once you subscribe to your first RSS Channel. PSP/SYSTEM/RSSCH: You can find RSS channels that you have subscribed to here. I won't be covering them here, instead I'll just give a brief overview. These are the basic folders, but there are actually more folders that can be accessed on the PSP. In the BROWSER folder, you will find files that store your browser history, as well as bookmarks. ISOCACHE.BIN stores the names of the ISOs available on your memory stick, allowing them to be displayed faster in the GAME menu. SYSTEM: In here, you will find a file ISOCACHE.BIN and another folder, BROWSER. Each save data is stored in its own folder, with the game ID as the folder name.

SAVEDATA: As the name implies, this folder stores all your saved data for PSP and PSX games. Like the MUSIC and PICTURE folder, the PHOTO folder also accepts one level of sub-folders. You can choose to put your pictures in either this folder or the PICTURE folder. PHOTO: This folder can store picture files as well. Portal pages are just HTML pages that have been put together for viewing on the PSP.

Homebrew in GAME will be executed using the kernel set in the recovery menu, while homebrew in GAME150 and GAME3xx will be executed using 1.50 kernel and 3.xx kernel respectively.ĬOMMON: You can use this folder to store portal pages for your PSP. GAME, GAME150 and GAME3xx: These folders are reserved for homebrew and PSX games.

Now let's get back to the MP_ROOT folder: As far as I know, they don't affect the operation of the memory stick with the PSP. You can either leave them there, or delete them. MEMSTICK.IND & MSTK_PRO.IND: These files are created when you format your memory stick with the PSP. I advise you leave this folder alone and just use the folders in MP_ROOT. VIDEO: This folder is supposed to be able to play videos, but if you've converted your videos to MP4 format using software like PSP Video 9 or 3GPConverter, they won't work in this folder. I've already covered installing plugins in a previous post, so refer there to learn more. Seplugins: Plugins for custom firmware go inside this folder. PSP: This folder contains homebrew, saved games and browser data. This folder supports up to one level of sub-folders, just like the MUSIC folder. The PSP can only read JPEG, TIFF, PNG, GIF and BMP formats, so make sure you have converted your pictures to these formats before you attempt to view them.

PICTURE: You can place picture files here for viewing in the PHOTO menu on the PSP.
