Audio Plugins
Several plugins are available to enhance the audio playback capabilities of the PSP. The MP3 Player Plugin for the PSP, for instance, allows users to listen to MP3s through the PSP's speakers, while simultaneously playing games. The PSP Audio Boost plugin increases the volume levels of the PSP, which can be beneficial if you are using the device to view online videos or listen to music regularly.
Visual Plugins
If you have trouble seeing your PSP screen at times, you may benefit from the installation of a PSP brightness plugin. The PSP Bright and Brightpad plugins increase the PSP's default brightness level and provide controls that allow you to manage the brightness of your PSP screen so you can increase or decrease the brightness when needed.
Customization Plugins
If you would like to make changes to default settings on your PSP, you can do so with customization plugins. The DayViewer plugin for the PSP allows you to set the date and time information on the PSP in any format that you want and the CXMB plugin contains custom themes you can use to transform the look of the screens and menus on your PSP.
Extra Features
Add new features to your PSP with a plugin that contains additional tools. If you would like to take screenshots of your PSP screen while a game is in progress, the PRXshot makes it possible. If you want to experience your game play in 3-D, you can download the PSP 3-D plugin, which works with a number of PSP games, including "Star Wars Battle Front 2," "Gripshift," "Prince of Persia - Rival Swords" and "Metal Gear Solid Ops."
