Custom firmware allows you to do things on your psp that you wouldn't normally do. Like playing gameboy games on your psp. Made by psp hackers its your choice whether you trust them or not. If you do the best way to get it is to use a Pandora battery only available at www.pandorasales.com. It only works with psp 1000 and 2000
Right now there isn't. If you want to get custom firmware for psp version 6.20 you need to downgrade to custom firmware using a Pandora battery.
No.
New version comes out is the best version but i should be custom firmware because without custom firmware you can not play free games in PSP.
I'm not sure what you mean by "the mod" but I think you may be referring to a "custom firmware". If so, you can safely format your PSP's memory stick without removing the custom firmware. This is because the custom firmware is stored in the internal PSP flash memory, not on your memory stick. If you want to remove the custom firmware, you will need to just install an official firmware onto the psp. The easiest way to do this is to put in a PSP game that comes with a firmware upgrade and choose that option. Then I would recommend having the psp do a Network Update.
Custom firmware is needed to do it, and if custom firmware is installed on the PSP in use, a plugin can be installed.
Custom Firmware is illegal<-----EDIT:Thats not what he was asking, please asnwer the question
No, you can't.

No. If you have psp 3000 it will but any other psp it will work.
custom firm ware is a modification of the psp that lets you use cheats,put ps1 games in the psp ,and much more. you can get custom firmware by makeng a Pandora battery and a magic memmory stick.(for psp 2000,and older)......for psp 3000 you have to get hue or somthing like that .
