When you format your PSP does the mod get deleted from the 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.

Where can you get Pokemon Shiny Gold for PSP I really want this?
All the video's you've been seeing on youtube with shiny gold on psp, or the forums you've been reading about people with Pokemon shiny gold on psp are all about people who have custom firmware on their psp's. You see there are two firmwares. The official firmwares created by sony, and custom firmware's created by hackers such as Dark Alex. There are many ways to go about getting custom firmware, which is essential if you want to be able to play emulators and roms such as shiny gold on your psp. First check around and see if there are any downgraders for you psp's current official firmware (I'm assuming you're on official firmware) If your psp is too high a version and their is no exploit or downgrader for your current version then you'll want to invest in a Pandora's battery and memory stick. These two tools have the capability to downgrade any psp firmware to 1.5 so that you may then upgrade to custom firmware. So to you or anyone looking to inquire about custom firmware just remember search engines are your friend and you're going to have to do a small amount of research to fully understand just what custom firmware is and how to obtain it. I wish you the best of luck.
