What is a PSP Pandora battery?

• What is the difference PSP original battery and the Pandora battery? Also, can I use any usb cable or do I have to get the PSP usb cable?

• Answer:

  the pandora battery is a psp battery thats been modified (as the previous poster said). the psp battery contains a memory chip. this memory chipped is programmed to activate the memory stick, before the psp boots up. by activating the memory stick, it then can over right the files that are stored on the internal memory of the psp. when you modify the battery to run the coding, then this is now considered a memory stick. there is also another way to make one called a hardmod. the hardmod requires you to open up the battery, and cut a pin. this pin then stops the psp from booting up, and forces a mem stick bootup.
