PSP Tutorial: Easy Home Screen Customization!

Ive finally done it! After long hours of asking, Ive finally found how to get the custom Home Screens working for the PSP. (Almost as good as geting free psp game downloads too!)

WARNING: I AM NOT RESPONSIBLE FOR ANYTHING THAT MAY HAPPEN TO YOUR PSP! USE AT YOUR OWN RISK!
This has been tested on a 3.03 OE-C PSP and a 3.10 OE-A’ PSP. Everything up to 3.40 OE-A should work, but I havent personally tested them. (others have reported success however)

With that out of the way, we’ll need some files:

Download the Imposer GUI Set here: http://www.sendspace.com/file/14d5d6
NOTE: Once youve extracted the files where you want, move the file imposer.exe to the C:/WINDOWS/ folder for the GUI to work properly.
Also, here are the RSC and the PRX to extract the bitmap images: http://www.sendspace.com/file/ab9gfk

PART 1: Extracting Bitmap Image
Heres where we get the file that we will use to replace all the images and lines from the home screen. I’ll be showing you with the PRX, but it works the same way with the RSC.

1.
2.
3.

This will leave you with a bitmap image with everything you need!

Part 2: Editing the Bitmap Image!
Easiest part. Just edit everything within the red boxes. Dont go on or over the red lines or you WILL Semi-Brick the PSP. Those are the only real guidelines, and these are the images that will appear on your home screen, so make em as you want! Also, the little box in the bottom left corner? Thats your background color. Fill it with whatever you want your color to be!
Note, when saving your final images:
The PRX bitmap must be 332×166, unpacked 24bit BMP.
The RSC bitmap must be 552×546, unpacked 8bit BMP.

Part 3: Injecting/Moving the Files!
This is where we take the modified Bitmap image, put it in the PRX your using, and drop it on your PSP!

1. Make a copy of the impose.prx you used earlier. Lets rename it 1impose.prx
2. Start up the Imposer GUI again
3. Input is 1impose.prx, bitmap is your modified bitmap image
4. Click the output button. Now in the “file select” window, highlight 1impose.prx and hit open.
5. Hit okay, and a file called 1impose.prx.prx should show up. Rename it to impose.prx
6. Plug in your PSP and open up Flash0 via Recovery Mode
7. You have 3 choices here. If you drop the impose.prx in your:
i) Flash0/kd/ folder, all your commercial UMD’s will have custom Home Screens
ii) Flash0/kn/ folder, all of youre homebrew will have a custom Home Screen
iii) Obviously, you can put the same impose.prx in both folders for UMD’s and Games to have custom Home Screens.

Voila! Fire up your PSP and see how it looks!

And here are some examples of what can be done with this:

That can be accomplished with this BMP:

Or this: (My first try using my method… I have since lost the BMP)
