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. This folder supports up to one level of sub-folders, just like the MUSIC folder. PSP: This folder contains homebrew, saved games and browser data. Seplugins: Plugins for custom firmware go inside this folder. I've already covered installing plugins in a previous post, so refer there to learn more. 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 advise you leave this folder alone and just use the folders in MP_ROOT. MEMSTICK.IND & MSTK_PRO.IND: These files are created when you format your memory stick with the PSP. You can either leave them there, or delete them. 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. GAME, GAME150 and GAME3xx: These folders are reserved for homebrew and PSX games. 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. Portal pages are just HTML pages that have been put together for viewing on the PSP. PHOTO: This folder can store picture files as well. You can choose to put your pictures in either this folder or the PICTURE folder.

Like the MUSIC and PICTURE folder, the PHOTO folder also accepts one level of sub-folders. SAVEDATA: As the name implies, this folder stores all your saved data for PSP and PSX games. Each save data is stored in its own folder, with the game ID as the folder name. SYSTEM: In here, you will find a file ISOCACHE.BIN and another folder, BROWSER.
