Ultimate flash0 Free Space Guide
v1.25.5
The contents of this guide will consist of information NOT listed in most other free-space-guides. This involves manual work on flash0 so I highly recommend keeping a backup of the file in question.
Useless files you can delete without concern of feature loss or the need to backup:
Spoiler!
dir: flash0:/vsh/resource/system_plugin_about.rco
description: copyright credits slideshow displayed from System Settings -> About PSP.
if: you don't have an attatchment Camera or don't have plans to get one before the next CFW upgrade
dir: flash0:/kd/usbcam.prx
dir: flash0:/vsh/module/camera_plugin.prx
dir: flash0:/vsh/resouce/camera_plugin.rco
if: you don't have an attatchment GPS device or don't have plans to get one before the next CFW upgrade
dir: flash0:/kd/usbgps.prx
if: you don't have an attatchment MIC or don't have plans to get one before the next CFW upgrade
dir: flash0:/kd/usbmic.prx
if: your CFW is 3.73 or below
dir: flash0:/vsh/module/update_plugin.prx
dir: flash0:/vsh/resource/update_plugin.rco
Fonts:
Spoiler!
If you A. don't speak or use japanese or korean fonts in the XMB and / or B. are on CFW 3.80 or above:
Relocating movable and / or customizable components of the XMB to flash1, flash2, or ms0: DO NOT TRY FLASH3, it is NOT mounted during any mode on any firmware.

If the file you're looking for is not on this list, that's because it hasn't been tried yet. Try it yourself and report your findings! Make sure you have your backup (which you will read about shortly) before trying anything though.
List of files which can be relocated:
flash0:/vsh/resource/01-12.bmp
flash0:/vsh/resource/13-27.bmp
flash0:/vsh/resource/impose_plugin.rco
flash0:/vsh/resource/system_plugin_bg.rco
flash0:/vsh/resource/system_plugin_fg.rco
flash0:/vsh/resource/update_plugin.rco
List of files which cannot be relocated:
flash0:/vsh/resource/opening_plugin.rco
flash0:/vsh/resource/system_plugin.rco
flash0:/vsh/resource/sysconf_plugin.rco
14. Click "File" and "Save As" to get your modified vshmain.prx
MAKE SURE YOU MADE A BACKUP OF YOUR ORIGINAL vshmain.prx (step 7)
Put your modified vshmain.prx in:
flash0:/vsh/module/
15. Cut & Paste the files of the file-paths you changed to your Desktop and connect flash1, flash2, or ms0, whichever you selected, to usb.
16. Create the file structure in which the file you're moving originated (or to resemble the custom file path if you decided to make one) in the drive you chose to relocate the files to. Drop the files off of your Desktop into their corresponding folders.
17. Reboot your PSP. All should be well.
18. In the event something does not work:
A. Replace the modified vshmain.prx via Recovery Mode at flash0:/vsh/module/ with the backup vshmain.prx from your desktop.
B. Return the moved files to their original folders.
if you meet every step of this guide, you will have 4-6, possibly 7mb free on your flash0 WITH 1.50 kernel subset installed.
on slims, the freespace numbers may get pretty big ;) please report them if you try it.
Don't do anything stupid :thumbup:

seeing that you have a phat psp, 4-6mb, up to 7. if you don't have kernel 1.50 installed, you could be seeing a number as high as 10-11mb
that is IF you do everything this guide has to offer.
(see blue text at bottom of original post)

Well, when i originally posted this, it wasn't completed, so the blue text wasn't there. But that is a MASSIVE amount of free space.

I didn't follow everything, But i deleted (on CFW 3.90M33-2, without 1.50 kernal installed) Camera_Plugin.rco and ps3scan.rco and replace the 3 font files and have 5.96MB free space. Very very good guide.

people have their own needs for flash space. for some, it may be experiments/developments, others (such as yourself) gameboots and cintro's, and i.... well, i have some sensitive files which i need to keep out of reach of some people in the house. brilliant eh?
i, unlike some other people, know what i'm doing, and know what is / isn't dangerous. therefor, flash0 is my playground.
myth: will the nand wear out after being written on excessively?
not at all, unless you write to it insanely more frequent than you would to a memory stick.
