You can restrict the PSP from playing UMD (movies or games) with a certain rating, for example, restrict children from playing games for over 12s. This can be done by accessing the Security Settings option from the Settings menu. The default code is 0000. Please remember that if you set the code and forget it, there is no way of resetting it.
Files can be imported or exported using many digital storage formats, including external hard drives and USB drives (FAT 16/32 format only). If you have a launch PS3 model, you can also use a selection of memory cards, including Memory Stick Duo and Memory Stick Pro Duo, SD cards, Compact Flash.
Simply insert the memory card/device and wait for the PlayStation 3 to detect the media. Select the item you would like to copy and press 
to bring up the option menu. If the item is not copy protected, you will be able to copy it to the external media.
Firmware 1.00 to 1.50
Homebrew for Firmware 1.00 to 1.50 can be loaded directly from the PSP XMB. Homebrew games should be placed in the “PSP/GAMES” folder of the Memory Stick. Some games may require certain steps in order for the game to work, please see individual games for more details.
Firmware 2.00 to 2.60
Homebrew om Firmware 2.00 to 2.60 can be loaded in two ways, either using the TIFF Exploit by loading a image from the XMB or by using the GTA Save Game Exploit. Both these methods allow the use of a EBOOT Loader that again loads games from the “PSP/GAMES” folder of the Memory Stick. Not all homebrew games are compatible with these firmware versions.
Firmware 2.70 to 2.80
With Firmware 2.70 to 2.80, homebrew can be loaded using the TIFF Exploit. If you are using 2.80, there is no EBOOT loader available, and as such, only a limited number of games are available. If you use Firmware 2.71, you are able to load homebrew directly from the XMB using a hack.
To backup your PS3 savedata to an external device, go to Game > [Saved Data] and press to bring up the menu. From the menu, select [Copy] and choose the destination. Data can be imported back to the PlayStation 3 if needed. It is recommended that you backup any important data.
Please note that not all savedata can be backed up. Depending on the model if your PlayStation 3, you may need a USB Memory Card adapter to copy data to memory cards. Copy protected data cannot be copied to external media either. For these games, your savedata is locked to the PlayStation 3 console and cannot be backed up in any way.
The PSP can be purchased in a variety of packs, these include:
The Base Pack includes only the PSP, the battery pack and AC charger. The Value Pack comes with everything you need to get started including everything from the Base Pack, plus 32MB Memory Stick Duo, Pouch, Cleaning Cloth, Headphones and Remote. The Giga Pack comes with everything fror the value pack, except the 32MB Memory Stick is replaced with a 1GB Memory Stick. The PSP Entertainment Pack (only available in certain territories) comes with everything from the PSP Giga Pack, but is bundled with movies that can be downloaded on to the Memory Stick.
Before you can use a Bluetooth device with the PS3, you must first register the device with the system. You can do this by going to Settings > [Accessory Settings] > [Register Bluetooth Device] and select the device you want to add. Simply follow the on-screen instructions to add the device to the system. Currently, the PS3 can only handle the following Bluetooth devices:
Bricking occurs when some code is executed on the PSP that alters the Firmware to an unusable state (i.e. it formats the flash on the PSP). This means that the PSP will not function properly and therefore make the device unusable.
Bricking in the PSP may occur when using homebrew that alters the flash, such as using downgraders, custom firmware and other flash altering programs. Current downgrader/daters are 2.0 to 1.5, 1.5 to 1.0, 2.5 and 2.6 to 1.5, 2.71 to 1.5, 2.80 to 1.5, 3.03 to 1.5. It is wise that if one comes across one of these so called downgraders to look for some form of proof.
To remove your custom wallpaper and return to the default XMB background, simply go to [Settings] > [Theme Settings] > [Wallpaper] and select [Original]. This option will remove your custom wallpaper. If you would like to replace your wallpaper, rather than remove, simply find a photo you want as your wallpaper and press to bring the on-screen menu. From the menu, select [Set as Wallpaper].
If you like to restore your original wallpaper, you can simply select [Wallpaper] from the [Theme Settings] menu and your previously stored wallpaper will be used. There is no way to delete the wallpaper from the system, you can only replace it or choose not to use it.
Homebrew is a term frequently applied only to video games that are produced or “home-developed” by consumers on proprietary game platforms (like the PSP); in other words, game platforms that are not typically user-programmable.
Folding@home is a feature under Network on the PS3 Home Menu. It is a distributed computing project that is run by Stanford University. The goal of the project is to research protein folding mechanisms in the hope that this will lead to medical treatments for related diseases. You can help out by allowing Stanford University to use your PS3 when is it idle. The power of the PS3 means you contribute a significant amount of CPU time to the project. More information can be found at http://folding.stanford.edu/.
