[Guide] The Flash Files' Functionalities

[xploren]

EDIT (August 8th, 2008): This guide is outdated. Unless you're on 3.00 or lower (maybe a little higher?), this guide will not help you.

Many people forgot which files handled which function on the PSP, so I decided to make a guide with all of the flash files' functions and jobs. Some files will indicate that they are removable from the flash.

NOTE: Statements with a “…?” or a “[?]” are not confirmed.
NOTE2: Some files are only for a specific firmware and every other firmware versions after it. Those files are marked with a “[!]” with the firmware version it started in.

I am temporarily only adding the flash0:/vsh/resource files. I will add more files later on, as I am still working on the guide. I hope this guide was helpful to many!
